need interface to CDC Keystone (92185) tape drive

by elson＠pico-systems.com

Hello, I was referred by a member, Peter Wallace. We are trying to recover some programs from 9-track backup tapes. I have a working 92185 drive, and had salvaged a SCSI - Pertec formatted interface converter off the back of a Cipher 990 drive at work. The Cipher 990 was total crap, hardly ever worked. The SCSI converter actually worked for a while, I was able to read a few blocks of tape (without a proper program to handle the format, I just did stuff like sudo cat /dev/st0 on a linux system, and got info that looked like the first couple records off a tape. Then, the converter died, it stopped passing its internal self test. But, I had proved the 92185 drive is OK. So, now I'm looking for a way to read these tapes. The best solution would be an off-the-shelf SCSI - Pertec converter, which were made some years ago, but will be hard to find on eBay or such. Another way is to find the SCSI interface board for the 92185, but I've never found one to buy. Another way is to get my Vaxstation running again, the hard drive blew, so it would take some effort to get that back up. I have a Dilog DQ15 controller for it, and if that won't work, I probably have another tape controller, too. Another problem with the VAX is I'd have pull all the data off the tape over a serial interface, it was last running VMS 4.7 without TCP networking. Anybody got any goodies in the basement, any good ideas of how to interface it, etc.? One other choice is to build my own FPGA Pertec interface. The formatted Pertec interface is about as simple as you could imagine, but I'd need to add an SRAM buffer to the FPGA to handle up to 64K byte blocks. Jon

AFAICR, you can not > simply install the RA70 in the SA72. Hum. Correct me if I'm wrong, but isn't the SA72 the box that holds up to 4 RA7x drives? Same physical size as one RA90? If so, then no, it don't hold 4 RA9x drives. Also, the RA70 works just fine in it, as do all RA7x drives. RA70 is somewhat unique, though, in that it was designed to also be usable without any front panel at all. So there are dip switches on it that can be used to set the unit number.

Unidentified Emulex card from 1991

by dennis_mailing_lists＠conus.info

Hi. I got unidentified Emulex card from, probably from 1991. It is 16-bit ISA, it has two connectors male DB-25 and male DE-15F (like on VGA cards, but male). It is probably multi-port card, but I'm not sure. Here detailed photos: Label: http://yurichev.com/non-wiki-files/unknown-emulex/emulex1.jpg Component side: http://yurichev.com/non-wiki-files/unknown-emulex/emulex2.jpg Back side: http://yurichev.com/non-wiki-files/unknown-emulex/emulex3.jpg Connectors: http://yurichev.com/non-wiki-files/unknown-emulex/emulex4.jpg Does anybody here know what this is and whether it's possible to get manuals?

Preferred image format for HP single-sided 3.5" floppies?

The 765 works just fine with 128 >byte sectors in FM mode. So Chuck ... do you know exactly how this works (as opposed to how it is documented)? 128 bytes/sector is a special case in the 765 (at least it is documented as such). According to the NEC documents, for the sector read and write commands, if you give it a value of 0 for 'n' (6th byte of the command = Number of bytes/sector), the actual number of bytes read/written is determined by the 9th byte written 'DTL' (DaTa Length). The docs don't go into much detail, and I haven't fooled with it much - I just set DTL to 128 when I am reading or writing 128 byte sectors (n=0). A few questions which are not clearly answered by the docs: under "READ DATA" "When N=0, then DTL defines the data length which the FDC must treat as a sector. If DTL is smaller than the actual data length in a sector, the data beyond DTL in the sector is not sent to the data bus. The FDC reads (internally) the complete Sector performing the CRC check, and depending upon the manner of the command termination, may perform a multi-sector read operatiohn. When 'N' is non-zero, then DTL has no meaning and should be set to FF hexidecimal" under "WRITE DATA" there is mention of N=0 or DTL ... but DTL is shown as a part of the write commands, and generally described as "DTL - Data Length - when N is defined as 00, DTL stands for the data length which users are going to read out or write into the sector". The read description seems to imply that the FDC "knows" the actual length of a sector, and only reads the number of bytes specified, while calculating the CRC over the whole sector. - How does it "know" the sector size ... the 'n' field in the ID header is the only place in the sector data that defines the size. - Does it assume the sector is 128 bytes? - or Does it actually read (and check CRC) on a smaller sector? -What is the actual behaviour during write? - Does it fill the remainder of a 128 byte sector with some value? - or Does it actually write a smaller sector? under "FORMAT TRACK" (in the chart notes) "(3) In MFM mode the FDC cannot perform a read/write/format operation with 128 bytes/sector (N = 00)" This implies that 128/MFM simply doesn't work - not even for format (which you indicated earlier actually does work). Is this a fairly reliable assumption? Does DTL have any effect on 128/MFM reads or writes? You mentioned that 80 bytes get transferred instead of 128. Does changing DTL make a difference? Or is it always 80 bytes? Dave -- dave12 (at) Dave Dunfield dunfield Firmware development services & tools: www.dunfield.com (dot) com Classic computers: http://www.classiccmp.org/dunfield/

All the machines and parts are located in the UK and at this stage I'm interested in expressions of interest. Please bare in mind that the machines are for pickup from the UK and would probably be impactical to ship.

DEC LP20 backplane wiring diagrams

by RichA＠vulcan.com

We have been trying to get working an LP20 printer interface on our 2065. We discovered just today that the issue we have had with bad control signals was not due to bad boards, but rather was due to the fact that the bottom 4 segments of the Unibus backplane into which the control card plugs have no (0) wires wrapped around the pins. We have the LP20 schematics, but the wiring diagram *for the backplane* is not included. It also is not to be found on microfiche, although there is a reference to it, with document numbers. We are specifically looking for 70-11427, 54-11704, and 50-11703. If anyone has any of these documents, please let us know ASAP. Otherwise, a young EE is going to have to spend time with the complete set of LP20 schematics and a spreadsheet program to generate a wire list and re-wire this thing by guess and by $DEITY, a process that will take several weeks with no guarantee of correctness of result.

Hi Liam, I am not sure if it does make much sense to address these polite "concerns" by the other chap... :) If the person making this statement can make boards for EUR 20.- each we'd be delighted to buy from him. For sure such price would be possible when making 100,000+ boards. We do runs of 100, we have to pay for electronics recycling (WEEE) registration, we pay tax, etc. I am sure hobbyists only doing a few boards can get around such things, we can't. We can't get even near this figure. For the record: the board is EUR 90.-; EUR 100.- is with cables we also have to buy to resell them. The donations asked for are for the preservation project, maybe it would have made sense to read the donations text file enclosed. And yes, even MS Office has student and pro editions available, I don't see anything wrong in charging companies that can afford to pay more. They keep it free for private users, at least for our product.

>On another mailing list that I am on, someone was expressing the >desire to retrieve data off some old BBC Micro floppies to see if it >would be possible to get some of the software running on a Raspberry >Pi. They do not own any machine with a floppy interface. My BBC's don't have drives, and I don't have any software disks - so I don't have a way to test this ... but ... According to the all-knowing google, the BBC disk system used an Intel 8271 and later an WD 177x controller - the 8271 does IBM 3740, and the WD is certainly capable of it (so hopefully they kept the format the same). So it seems to me that there is a reasonable chance that these disks could be read with ImageDisk - granted he'll need a DOS/floppy capable PC (or a friend with one), but it might be worth a try.

Seemingly complete DG S/230 16 bit Eclipse system

by chris＠mainecoon.com

On ebay, item 230754098992. The seller is somewhat clueless about what he has (it's an 80s machine, not 60s) and is probably missing a zero from his estimate of what the thing weighs, but otherwise it looks complete and in good condition save for a couple of rack filler panels that look like someone drove into them. From the photos it looks like two 1600BPI drives, a couple of 8" Fuji SMD drives with some sort of emulating controller and three IAC-16s or equivalent. No affiliation with the seller, save for the fact that I'd be bidding on the thing if I could figure out how to get it from VA to CA. -- Dr. Christian Kennedy chris at mainecoon.com AF6AP http://www.mainecoon.com PGP KeyID 108DAB97 PGP fingerprint: 4E99 10B6 7253 B048 6685 6CBC 55E1 20A3 108D AB97 "Mr. McKittrick, after careful consideration..."

Things available in Minneapolis?

by jules.richardson99＠gmail.com

Hi all, Just wondering if anyone knows of any vintage equipment available in the Minneapolis area? I'll be heading down to Bloomington this coming Saturday for a few days, and - for once - will have a van with me which will have a bit of free space inside (normally on such trips it ends up full to the gills with other stuff :-), so I could potentially pick something up on the Sunday or Monday to bring back with me. I am actually picking up a QX-10 on the way down there, but I think I'll have a bit more room for something else so long as it wasn't too big/heavy. cheers Jules

Hey Tony, no it can't. Jean did not use "the technology". He got the information from us and never signed an agreement, NDA or whatever. If you look at the current rel. 2 of KF 2.0 b9 for the Mac you will find that I already made a quick fix to the definition of derivative works (threw out the formats). This will be refined even further.

Apple 1 programs

by sellam＠vintagetech.com

I just re-discovered a directory on my server that has Apple 1 or at least 6502 programs in hex dumps and also object code that was apparently "assembled" using a PHP script I guess I wrote at some point in the past that I also found in the directory. I've long forgotten from where they came, and what they are doing there, but while they are there I figure other people should download them, especially Apple-1 tinkerers.

Discferret broken?

by cb＠kryoflux.com

> I will answer in brief. Hi Dave, so do I. now I think I understand the issue. It's about the (old) open source discussion and daring to ask for money. I really don't feel like arguing against that. What I know is that people deliver good work when they are motivated. I see no evil in the fact that people get paid because this can be a very good motivation. It also enables you to spend money for things that make the product better.You also can spend the money to train programmers so they use latest techniques and don't do beginners faults. I don't speak for everyone involved, but: I scan artefacts with a commercial scanner software, I process images with Photoshop, and I use TotalCommander to organise files and put them up on the FTP. This does not mean the images scanned and archived are less preserved. I would not want to exchange a single tool. I enjoy using them every single day.

Sure this might cut into the profits > of some, but if the goal is profits (or even amassing a large private > collection), then you're in the wrong business. > To give you a brief sum up of what has happened since 2001: The project / org was founded by a programmer (Istv?n F?bi?n) that was so upset about only pirated, obfuscated copies of his games being in circulation that he tried to submit the games to some project that would care about storing true and unmodified original mastering data. There was none, so CAPS (The Classic Amiga Preservation Society) was born. F?bi?n developed a toolchain that would allow for using an Amiga 1200 (which has a special floppy controller; actually none) as the ingestion device. This data would then be processed and stored as IPF files. Over the years the toolchain and the number games preserved grew. The project was renamed to SPS (The Software Preservation Society) as it became evident that other platforms had the same (no mastering data being preserved) problem. It also became evident that the Amiga as the ingestion device won't be around forever. It is a dying platform. Hence other technology was inspected but no solution satisfied our needs (capturing unprocessed flux changes as delivered by the drive). By 2008 the project had spent more than EUR 50.000 on buying games; most of this money was donated by project members. Please consider: There are a few games you care about personally, but you pretty quickly reach the point where you have acquired all games that matter to you? In 2009 we picked up the Cyclone20 project by Rich Aplin. Rich and me worked for Cachet back in the day and Rich was the inventor of the original Cyclone (a duplication tool that would force feed data read to the target drive). Rich had lost interest so we decided to develop the proof of concept to something usable. It took us about 1,5 years to redesign everything and to move from prototype to production status. Just for the record? until then we only had gotten very few donations for SPS which were spent on - you might have guessed it - buying and preserving games. The digital assets produced are given to libraries, museums and back to the original contributors. Some of these also share the images. Something we can't do ourselves without jeopardising the project. When KryoFlux was ready we decided to sell it trough a company, to protect ourselves (things can go wrong, people can try to sue, etc. - you don't want to risk your personal life for a hobby) and to give this thing a legal basis to build upon. When you sell hundreds of boards, regardless of your margin, you better are registered for electronics recycling and you better pay tax. The money earned is intended to pay for the expenses, but also help establish SPS as an NPO, and of course? help buying more games. In Japan, gamepres, run by one of our members, was already accepted as an NPO. Because of this, KryoFlux was never made because we thought it was a cool thing to sell, it was and still is the tool we needed and we made it happen after several others said they could / would, but never did. I have no idea when I really spent an evening on playing a classic game? > Concerning SPS, I think the fact that only game dumps are accepting is > rather telling. There is a load of software, for Amiga and other > platforms, which is at least as important to preserve. The other day I > talked to a former Amiga game developer, who mentioned that Digi-Paint > was used heavily in game development.

But when you are a group of five or less, you have to focus on something. Games came with high profile protection techniques. These can't be stored by standard sector dumps. It was therefore decided to focus on the most precious stuff and hope that others would do the more easy part. But we always took dumps of apps when we could get them, and we still do. We e.g. have various versions of DPaint. A quick look in the archive shows we have 2-5, physically and digitally. > I may be wrong about this, but in regards to preserving this stuff, > personally I'd trust an open, helpful group like BitSavers much more > than a private group interested in selling their products. Maybe the above helps explain things? It's odd, but things become really complicated once money is in the game.

Displays (Was: COSMAC Elf 2000 - TIL311 displays)

by rickb＠bensene.com

I love the TIL-311's. I used them to make a display for a microcode ROM dump fixture for Wang 700-series calculators. Having the latch, decoder, and LED display all in one package made the whole thing a lot easier to build. Plus, the display just look cool. Desktop electronic calculators used just about every kind of display technology there was beginning with the Burroughs (and licensees) Nixie tube. Here I list some of them, and some examples (some of which can be found on the Old Calculator Museum website, http://oldcalculatormuseum.com). Nixie tubes were extremely popular in the early days, beginning with the first electronic calculator (Sumlock/Anita Mk 7 & 8), and lasting into the mid-1970's. The SCM Marchant-I "handheld" electronic calculator used Nixie tubes...the only "portable" electronic calculator that I know of that did this. There were also the unusual Nixie-like displays, where a number of digits worth of Nixies were combined into a single tube (Lago Calc LC-816). Small vector CRT displays were used on some early desktop calculators (like Friden 130/132, Friden 1160-series, SCM Cogito 240SR, Victor 14-32x series, and HP 9100A/B, with a few others) , and were very cool. Canon's early electronic calculators (Canon 130, 161, 130S) used edge-lit plastic panels with grain-of-wheat incandescent lamps to light the plastic panel from the edge. The panels had dots etched into them in the shape of digits to catch the light and project it out as numerals to the user. These were abandoned when Canon switched to Nixie tubes, as the edge-lit panel displays were simply too expensive, and tedious to repair when the lamps burned out. As Nixies started to wane in favor of less-expensive display technologies, lots of manufactures went to Burroughs Panaplex panels, which were less expensive, and easier to interface. Lots of machines (of few of which are Wang 600, Commodore US*1/US*8/US*10, Victor 1800-series, Friden 1203) used these panels. A few machines also used tube-type versions of 7-segment gas-discharge displays, such as the Passport CA-850(clone of APF Mark I), and Sperry-made multi-digit gas-discharge modules (Commodore US*14, Tektronix 31). LEDs came on board on some desktop machines (MITS 1440, HP 9800-series), but ended up really being the display of choice for the new up-and coming handheld machines, until VF, and later, LCD displays usurped them. There weren't all that many desktop calculators that ended up using LED displays. VF-style tube displays also took over in desktop and some handheld machines as the reign of gas-discharge tubes and panels came to an end. There was some interesting VF tubes, most notably, the Japanese Iseden-made Itron tubes that had a unique segment rendition to make digits look more "handwritten". These were first used on Sharp's QT-8D calculator, which was the second (though the first successful) electronic calculator to use a MOS/LSI chipset for all of the calculating logic (with the much earlier Victor 3900 actually claiming the title of first, but there were some major problems with the machine that led to low production figures, and many of the machines being recalled). These displays were different enough to make them engaging. Sharp used them on quite a number of desktop and "handheld" (EL-8, EL-8M) machines. Alas, the days of these displays is pretty much gone. LCD and VF panels have replaced them all in calculators, as well as all kinds of other stuff like kitchen appliances, gas pumps (for a long time gas pumps used really large Beckman gas-discharge displays), instrumentation, copiers, audio equipment, and just about everything else that needs a display. Though not used in any calculator that I'm aware of, the Burroughs "Self-Scan" displays, which were gas-discharge dot-matrix displays that used fancy manufacturing techniques to build the shift register that held the state of the dots into the display elements themselves (essentially a planar version of an old Dekatron tube). Data would be clocked into the display and it automatically shifted as the dots were being shifted in, and when static, no refreshing was required. These were used for in displays for early electronic point-of-sale cash registers that would display information about the item as well as the price. They were also used a lot in some early portable data terminals (with a few lines of perhaps 20 characters each). They were also quite popular in Computer Numerical Control (CNC) controllers for displays showing the status of the machine. They significantly reduced the complexity of making a device with a flexible alphanumeric (or even simple graphic) display. These, too, met their end when VF and later, LCD dot matrix displays replaced them. Displays have always been an interest for me, and dovetails well into my calculator fixation. Rick Bensene

> So you're making the claim that the file formats are fully open, > fully documented, and anyone can extract the data at any time, > regardless of the status of KryoFlux Ltd? Hi Dave, yes - that was the intention of putting the source up there. The old licence will be tidied up more and more, but again, to make something available now, the IPF source was released with a very short and permissive licence. I would also like to point out that there's a very informative third-party website around that's run by Jean Louis-Guerin. He's helping with seeing things from the user side. You tend to become blind for the obvious when you do things for a long time. http://info-coach.fr/atari/hardware/devices/kryoflux.php There's much free info there, and it also has another document on the STREAM format produced by KryoFlux. Someone mentioned he'd regard the file format as documentation (which would then be covered by the licence), so here's an independent source: http://info-coach.fr/atari/hardware/devices/kryoflux/kryoflux_stream_protoc… You might want to take note of the fact that this is independent stuff and we've encouraged Jean to release whatever he wants to release.

This applies to all data ever read with the unit.

more on strange PCB "short", fixed!

by mcguire＠neurotica.com

I've fixed the short problem. It was my mistake. It wasn't a bug in PCB (thank heaven) but PCB's short detection/highlighting code sent me all over the place looking for it. I'm not sure if there's a better way to handle that or not. Basically a component on the other side of the board, an 0805 resistor, was supposed to have one of its pads connected to 3.3V. Instead it was connected to GND. Tired eyes and a tough deadline is what I blame. :) For some details (which I actually started typing as I narrowed this down, before I found the problem, so it'll read weird) see below. Thank you, everyone, for your suggestions! -Dave I deleted the 3.3V and GND planes, and narrowed it down to an 0805 resistor. One of its pads is highlighted in orange. If I delete that resistor, the short goes away. When I put it back (by placing a fresh 0805 from the library and giving it the same refdes) the short comes back. One pad of the resistor is connected to GND. It goes nowhere near 3.3V. I've deleted and redrawn the traces going to that resistor, checking for the short after every move. I've narrowed it down to one of that resistors pads; the one that gets highlighted in orange. That's the one that connects to GND. If I delete the trace that connects that pad to GND, the short goes away. BUT!! I've delete the GND plane, and the via w/thermal that connected that trace to that plane. It connected to another resistor's pad, which was erroneously connected to the GND net, when it was supposed to be connected to 3.3V. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Fast Eproms CY7C291 Data?

by holm＠freibergnet.de

I want to bould my own PDP11 some day but in an other way as other people here :-) I want to build an Bit Slice CPU out of AM2901 Chips to emulate the PDP11 CPU. As a prt of the design I'LL need some very fast Proms for the microcode and I've found the AM27C291,TMS27C291 and CY7C291 Chips, they are fast and big enough (2Kx8 and 25-35ns). I'mm looking now for a data sheet from the CY7C291 that describes the programming algorithm, getting a datasheet is easy on http://www.datasheetarchive.com/ but there is this sentence in the text: "Programming Information Programming Support is available from Cypress as well as from a number of third party software vendors. For detailed programming information, including a listing of software packages, please see the PROM Programming Information located at the end of this section. Programming algorithms can be obtained from any Cypress repesentative." Ok, so far so good. I don't know of what end of which section I schould look for the programming information, since I don't know from where the datasheet was scanned from. I've contacted Cypress itself some time before..to make it short: they failed. The sold the entire Eprom bussines years agao (forgot to which company) but wheter cypress nor the new company has the required information or want to share them. So please: Maybe someone has this old databook from cypress and could look "at the end of this section"? I got the algorithm for the TMS in a datasheet, but according the german company "Conitec" that makes programmers (have a GALEP-III from them) that seems to be not the same on the CY7C291. The guy there couldn't program my samples I've sent to him. Any help? Regards, Holm -- Technik Service u.

Browsers for OS/2 2.1?

by cclist＠sydex.com

On a whim, I installed OS/2 2.1 on a P1 system last night (Hint: it helps to have a multi-boot setup with a network-capable OS on one partition--saves a lot of floppy work). I could get MS Lanman for OS/2 working okay, but then I ran into a problem--it seems that FreeTCP and most browsers for OS/2 say "Warp 3 or later". And getting a browser-suitable TCP/IP stack seems to be no small issue. IBM Web explorer seems to want Warp as well. Lanman has a TCP/IP stack of sorts, but it's undocumented and apparently used only for NetBEUI protocol. The only TCP/IP program that uses it seems to be the "ping" packaged with Lanman. Has anyone ever gotten a browser to work on 2.1 over an ethernet TCP/IP connection? If so, how? Thanks, Chuck

An interesting claim: Olivetti made the first ever PC,

by stevew＠ka6s.com

Well - I'm going to vote for Calculator - though I learned to program on one of these back in the early 70s. I wrote a couple of simulators for them to learn Fortran - and still remember a few details. 1) The machine had a total of 120 instructions if you used up the upper registers with instructions (so it WAS possible to carefully do self modifying code if you were so daring.) 2) When you used needed those registers - it would be 60 instructions. The machine was very useful as a training vehicle for preparation to run into things like the Altair with 256 bytes, etc. I look upon the P101 with a lot of fondness! Steve

old == worthless.

by robert＠irrelevant.com

Bl@@dy ebay sellers... I bid on, and won, a Tandata TD4000, complete with what looks like a matching branded monitor. Cost me the grand sum of 99 pence - nobody else wanted it. Called yesterday to arrange collection, got "oh, we got it out for you and it looks like it was broken when we moved house". How broken? "a crack, and there's a cable missing." told them no worries, would still have it, should be able to fix it. "but my husband has put it out to be thrown away". Told her to go check if it was still about, I did still want it! Got a call back today, "it was put with some old PCs and they've all been taken away this morning.." Would they have done the same if it had been an iPad? Or it it had sold for more than a pittance? I'd certainly have paid more! The problem is, old == worthless, and if it's worthless (reinforced by it selling for almost nothing, even though that's all they asked for) then it doesn't matter. OK, it's not like it was a set of backup discs from Prestel itself, just a terminal to access it, but it's still galling. (The other, I'd drive to the other end of the country to kick down their door if I thought it would put me on the trail of them!) Sigh.. Anyway rant over. Wonder if I can justify leaving them a Neg...

Discferret Broken?

Jonathan, I think you misunderstood what this is about. Before I go into detail here, it does make sense to see how "the technology" is defined: "The program's object code, source code and documentation are collectively referred to as the "Technology"". Please note that there is no reference to the file format itself. It just clearly states one thing: You can not take a piece of our software and use it to make another piece of software, except for the exclusions listed. It does not say you can not invent something on our own or work with a CatFerret or DiskWeasel or whatever device comes to mind. It is also correct that you could not take the capsimg.dll and put it into a competing product. You can of course write your own code, or you could - if it's not a commercial thing - just take a look at our source distribution. It comes with a different (adapted MAME) licence! Please take a look yourself: http://www.kryoflux.com/download/ipfdec_source4.2.zip This was released to make sure the format is a) fully documented, b) portable and c) data is not buried. The reasons for the tight restrictions of the original (old) licence were e.g. some companies selling game compilation CDs of questionable origin, which usually did not give credit or pay royalties to the legitimate copyright holders (=game devs). We did not want to support such things. Not being able to use IPF for these (or extract the data with our enabler) meant ADFs were used, which usually sported cracker intros or similar, making people aware of what they had bought. > This is one of the most deceptive licenses I've ever read; the top > preamble implies it gives the user great freedom but instead it almost > totally locks everything they've done and can do down to "a SPS product > defined by SPS".

No, you are not (I think). Unless you take parts of our product to enhance a competitive product, all is fine. In other (unpleasant) words: If you make your own and don't steal, I don't see any problem there. > No wonder none of the organizations you sold your CTA analyzer to want > anything to do with Phil's product, the license expressly forbids them > from even considering it. Absolutely not. If they were using this very same licence (which they don't, as it excludes commercial use) they could of course use other products. They just could not put parts of our product into the other.

Discferret broken?

> If this is how you think about others who are trying to preserve data and history, I don't think you should be involved in preservation at all. Thanks for making up my mind in regards to your product. Dave, to be honest, going back to your very first email... I really looks like you had made it up right from the beginning. I have no clue what preservation and the right to do it or not has to do with one's right to stand up against a competitive claim that has proven not to be an issue at all. I also don't know what either product has to do with preservation per definition apart from ingesting data. Preservation is much more than reading some bits, it's making sure the data you have is authentic and valid and can be recreated physically and in emulation any time.

Put on the hip waders

by aek＠bitsavers.org

http://www.ebay.com/itm/220970605899 This ICBM COMPUTER is one of ONLY 10 that were armed and ready to fire at Russia or anyone else if necessary during the cold war arms race. These are credited for stopping the soviet union from placing nuclear missiles in CUBA in 1960 to 1962. They were decommissioned by the strategic are command and the hard drive and memory banks were erased. This is the first personnel computer that could run with commands on its' own. The movie Dr. Strangelove was a scary horror comedy about these missiles and the people that might push the button, and not be able to stop if needed. -- This this is clearly a dangerous munition, so I've reported it to eBay. I would suggest others do the same, for the safely of our children and our precious bodily essence.

On Programa P101

by bdamer＠digitalspace.com

In concurrence with Rick here, I was interviewed last year by some Italians making a documentary about the Olivetti P101 trying to shoehorn their claim it was the first "personal computer". I categorically stated that it was simply a programmable calculator and not a computer. I noted to them the features of the 1962 LINC (OS, languages, removable storage, interactive programming/display, peripherals) which was described by Alan Kay and Gordon Bell as "the first personal workstation" or "where the experience of personal computing was first possible". Seemed to fall on deaf ears. Did their documentary ever come out? bruce ever the CC lurker

No, because the moment you would be able to put data into an IPF, you would also have the tool to extract it again, you would not use parts of the free distribution to do that. And you would of course have your original data in the first place. As outlined in another reply this mainly addresses companies releasing bogus compilation CDs which we did not intend to support. And apart from that: Our source distribution comes with a different (adapted MAME) licence! http://www.kryoflux.com/download/ipfdec_source4.2.zip This was released to make sure the format is a) fully documented, b) portable and c) data is not buried. > It most certainly would cause me to include them out of anything I > might do as an individual.

Wanted: TRS-80 8-Megabyte drive

by eric＠brouhaha.com

I have a TRS-80 Model 16 with an 8 Megabyte drive, but unfortunately the drive is a secondary, not a primary, so it doesn't contain a controller and I can't actually use it with the Model 16 at the moment. Does anyone have an extra 8MB primary drive they'd care to part with? Or the controller board from inside an 8MB primary drive? (Or, for that matter, another secondary?) The Model 16 (or Model II) with the original hard disk interface[*] will ONLY work with 8MB drives, and not with the later 5, 12, 35, or 70 MB drives. Similarly, the 8MB drives will only work on the Model II or 16 with that original interface, and not on the Model I, III, 4, etc. The pinout and signals of the cable between the interface card in the computer and the controller in the primary drive is different than all of the later ones. Both the old and new TRS-80 hard drive interfaces use a 50-pin cable with signals similar to those used by a WD1000 controller, but neither are actually directly compatible with the WD1000 or each other. Radio Shack added some functionality beyond what the standard WD1000 has, and changed the pinout. Thanks, Eric [*] The original Model II/16 hard disk interface can be recognized by the red power distribution strips under the DIP ICs.

KryoFlux power rail (was: Re: Discferret broken?)

by cb＠kryoflux.com

> > Though I was not specifically responding to the concerns over KryoFlux, > I would refer not to the input protection response, but this one: "and > there's lack of protection overall, especially in the power supply.". Like ZoomFloppy KryoFlux does not need external power at all. It is a bus-powered device. However, we added the option to feed in external power (just in case). There are two options for this power rail: protected (the user feeds 7-9 volts via the low voltagee connector or +12 via the molex, both are exactly regulated to +5V for the +5V rail and secured with a diode) or unprotected. Users are advised not to use the unprotected rail (needs changing a jumper) unless they know what they are doing. >> > I would really like to avoid the impression something is broken. It's >> > not, it's working. > I think it would be helpful to address the power supply protection > concern. Rightly or otherwise, prospective customers could conjecture > that this might impact or damage their precious disk drive mechanisms or > electronics. As I said... it's bus powered. And protected with voltage regulators and diodes. How much can you do with 500mA and +5V? I don't see any risk for the drive attached. Of course you can always be more protective, but at what cost? If you look a popular electronics you will find that there are some things you simply rely on. Like the correct voltage coming out of the USB port, a switching PSU or the correct polarity of a PSU. I found a friend's SNES dead because it simply has no protection diode. He'd attached a replacement PSU and soldered the connector himself? Wrong polarity. Oops. I am not saying that completely leaving that out was a wise idea, but it works for them. I am pretty satisfied with what we have. In other words? an airbag is fine. Putting the whole car in some kind of styrofoam makes driving a hassle. > > I took my position from > "http://forum.kryoflux.com/viewtopic.php?f=3&t=3#p1230.

You would need the Analyser to create IPF files as this is beyond the capabilities of DTC. IPFs are not the result of a conversion process, instead it's an auto scripting feature that will, for most disks, describe the mastering data. The rest needs manual adjustments. > I do have to handle feedback and questions for such a product, and I > understand it's a pain at times.

IBM, DEC and a backache

by silent700＠gmail.com

So once again I heed the call of classiccmp in distress and once again the mini-truck was packed to the brim and riding low. We cleaned out a storeroom of a small college last weekend and finally got everything unloaded last night - everything that would fit, that is. Had to leave some TRS-80s behind (always painful) but fortunately they were scooped up later the same night by another local collector. Here's my haul: https://picasaweb.google.com/102190732096693814506/March1Haul The incomplete inventory: - 5x IBM RT systems: 3x 6150 towers, 2x 6151 desktops - some variances in name and badging amongst all these which will have to be explored - 6x IBM RT monitors: 4x 5081 "Megapel" displays, 2x 6154 "Advanced Color Graphics Display" (I don't know which, if any, of the RTs have the necessary Megapel card) - 2x IBM 6157 Streaming Tape drives, one apparently NIB - IBM 8228 Token Ring MAU, NIB - IBM RT 8-port serial cards and break-out boxes, some boxed - DEC half-rack - DEC PDP 11/23 Plus system to be inventoried soon - quick check shows 11/73 CPU upgrade and Emulex SCSI card - Emulex PE02 Medley drive - Boxed DEC VT220 terminal (not sure if it's unused or not) - Boxed DEC LK201 terminal keyboard - IBM RT keyboards, not enough for all these systems - Various IBM RT docs, some in box - Various ISA cards to be ID'd later I already owned an RT desktop (6151 of some sort) and a small monochrome display which, if I went downstairs to check, would probably turn out to be a 5151, so I'm marginally familiar with RT stuff. But now that this load has appeared, more opportunities are opened...especially when it comes to graphics. It will take some weeks to ID all this stuff and figure out what's what, but I'd love to see the "Megapel" system in action. There are a few disks in the documentation box but I don't believe there is an OS. Anyone know if there are images out there? I think these things use regular PC floppy drives so hopefully the disk format is writable with the tools out there. Or, did the OS come on tape instead? If I read the right FAQ, RTs used ESDI drives. Imaging these drives will be a priority. I have an ISA ESDI controller (somewhere) that I could possibly put into a Linux box. I have no idea what filesystem early AIX used or if there is a way to mount it in another Unix. If the RTs work (or at least one does,) I could dump to tape or some other removable media instead. Despite the size of this haul....no mice. And of course, like the keyboards, IBM RT mice are proprietary, or at least the connectors are. I'll have to check the FAQs and such out there to see if anyone has adapted a PS/2 mouse to it. If these did have the graphics boards, I'd expect to have seen mice with them. But thanks to their size and relative uselessness, those mice were probably the first things to get tossed out :( Now on to the PDP...haven't dug into the cards inside yet but I do see an Emulex SCSI board, so that is automatic win. Can anyone ID the PE02 drive? I can't tell if that's 1/4" tape or what? Google isn't helpful. Taking on that half-rack is the reason for my post for the free SA600 rack (no takers yet on that, btw.) Despite what the realtor told me, the basement is a finite space. I am trying to find more info on what these machines did. I was told the PDP was used for students learning Pascal. Stuffed into its case was a printout with instructions on booting it into UNIX, so that's probably what it ran. The RTs did some sort of administration task at the college, so I am expecting to find AIX on them rather than AOS, the "Academic Operating System" that was used on some RTs in educational settings. I've found the RT FAQ and pcrt.info (which looks like a spam site) so far....any other RT experts or resources will be appreciated. With some luck and work, VCFMW's on-site server may be running AIX 1.x this year ;) -- jht

Free DEC SA600 Rack - Illinois

by silent700＠gmail.com

Thanks to the recent adoption of yet-another-DEC-halfrack, a DEC SA600 rack needs to go. Here are some pics: https://picasaweb.google.com/102190732096693814506/DECSA600Rack The cable frame and the SDI cables on it are no longer here. It's a bit of an odd rack, having held the massive RA90 hard drives in its previous life. I believe once those brackets are removed, normal rack holes remain, but I can't be certain. As seen in the pics, I cleaned it of most of its rust and it looks pretty good. Purists will want to repaint it. Local pickup only in the NW Chicago suburbs. It's about 5' high and weighs a lot more than it looks like it should. Be prepared for a battle getting it up the stairs. -j

Minor ImageDisk update has been posted

by dave12＠dunfield.com

Just an FYI : I've posted a minor ImageDisk update to my site (It's been a while!) Nothing major: - Added IMDA (ImageDisk Analyze) utility to examine a .IMD image and suggest drive types and settings that can be used to write it (a lot of people seem to have trouble with this) - Added a couple of batch file to automate presetting a .IMD comment from a text file, and extracting/editing/replacing the .IMD comment. - Enhance DMK2IMD to detect and provide a work-around for images with bad address marks apparently produced by some emulators. - Update .IMD file format specification to provide for representing disks with non-standard sector sizes or mixed sector sizes within a track. - Minor documentation and help files updates. I've also posted a raw binary floppy image (suitable for XDISK, Winimage etc.) to create a 1.44M bootable ImageDisk floppy that: - Has USB mass-storage and CD/CVD support. - Allows you to set a RAMdisk size when it boots, and runs from the RAMdisk after boot - so you can boot from a floppy and then read/write images to and from the RAMdisk (and USB mass storage). - Has tools to move files to/from the RAMdisk via: Network** (FTP, TFTP, DDLINK) Serial or LPT (DDLINK, XMODEM) **Over 100 network drivers are on the disk. - Can be used for a bootable CD/DVD. This might be useful to anyone who doesn't want to dedicate a DOS partition. -- dave12 (at) Dave Dunfield dunfield Firmware development services & tools: www.dunfield.com (dot) com Classic computers: http://www.classiccmp.org/dunfield/

Surface mount wasn't invented when it was written. The bit about the joint being mechanically sound refers to wires soldered to tags, lugs etc, where strain or vibration could cause the solder joint to break if the wire wasn't mechanically fastened before it was soldered. For devices built for use in vehicles or industrial environments I think the argument is valid, for office environments probably less so. Also, I am under the impression that heavier surface mount items would be glued down as well as soldered? Obviously, whether the solder will hold or not depends on the weight of the item being soldered and the stresses the device is subjected to. I recently bought a signal generator off the 'net which arrived non-working, because a large (about 2 cm diameter by 10 cm high) electrolytic capacitor had broken loose at one of the solder joints. It was only held by the solder joints. Another problem I have seen, which relates to surface mount devices, is that the instrument cluster on my car (a 1996 BMW) goes dead every now and then, only to come alive again after a moment. A number of people have reported that this appears to be due to bad solder joints on the PCB, which has a number of surface mount devices. /Jonas

EDN 4th Annual Microprocessor Directory, Nov 1977

by chrise＠pobox.com

I've been going through folders, files, listings and other things I received from the estate of a local OP who passed away several years ago. He had saved this EDN article from the November 20, 1977 issue titled "EDN's Fourth Annual Microprocessor Directory". I scanned it including the ads because it's kinda fun to see what was selling back then. You can see a little about the GI CP-1600 which was recently discussed on this list too. https://docs.google.com/open?id=0B6A73VHTVh23eWdNRUxHRkVUbXlDZHBRMGJRbmRkdw Chris -- Chris Elmquist

Discferret Broken?

Christian, if there's no anti-compete clause in the license, then please explain what exactly clauses 3.a.v and particularly 3.a.vi do. Also, for third party/open-source IPF stuff (other than the potential for GPL software to be used commercially, already expressly forbidden by 3.a.v), clauses 3.d.i and 3.d.ii would also seem to expressly forbid it? 3.d.ii seems to imply that it violates the license to even convert an IPF to other formats, which makes IPF images entirely useless as a general preservation format because of the legal minefield they're stuck in. This is one of the most deceptive licenses I've ever read; the top preamble implies it gives the user great freedom but instead it almost totally locks everything they've done and can do down to "a SPS product defined by SPS". I'm going to stay far, far away from any products Kryoflux LTD./SPS puts out unless you seriously rethink your licensing, since by contributing to the Discferret project I'm apparently already in violation of it.

PDP 11/04 w/RX01 and spares available, Cambs UK

by witchy＠binarydinosaurs.co.uk

Folks, I know a few people who'll be interested in this, given my recent need to find a new home (again) for me and my collection I need to shift more DEC stuff, in this case a PDP 11/04 with boxes of spare core etc and a complete RX01 floppy drive. The machine's PSU is toast (and set to 110V, beware!) which is why we got it at work in the first place, but that's all that's wrong with it. Shipping isn't an option unless you've got deep pockets I guess, so collection from Cambs in the UK, postcode CB6 please.

I understand the technique, and for a straight stairway, I think it would work just fine. In the 100-year-old house I was doing this in, there's a landing and a 90 degree turn to the left in the middle. The top of the rack would hit the wall while the bottom of the rack was still 3-4 stairs from the landing. Oh... and there was a stained-glass window at the landing as well (not broken by me, but later, when someone was moving a mattress, the window did not fare well). The rack had to go up the stairs nearly perfectly upright, except for the middle of the stairs, when it had to be tipped back about 10 degrees to clear the sloped ceiling. Again... I will never repeat that experience solo. I almost ended up at the bottom of the stairs under the rack. >> Is there clearance between the side of the H960 and the grey sides for >> the M6 bolt heads, or does your rack lack the hang-on metal sides? > There is plenty of space.

It didn't fit my car... :-( Gotcha. I remembered that some racks had the cluster of large pop rivets and some were welded but I wasn't sure which were which by model number. I spend more time in front of the machines than figuring out how to move the empty racks up impossible inclines or into impossibly small automobiles. A VW Microbus, BTW, can haul two H960s if you drop the rear seat and remove the middle seat - you just slide them in one at a time and load the middle area where the bench seat used to be with all the CPUs and disks you just removed from the racks. Easiest time ever. *That* works solo. Second easiest move was a VAX-11/750 in an Astro Minivan with no middle seats. The only hitch was the swivel chair mounts were taller than the casters, so the bottom of the VAX hung up on insertion and removal. Even so, it was still possible (and safe) solo. An 11/750 is mostly air and not as heavy as some things of similar size (like tape drives). -ethan

Discferret broken?

Hi Brian, > * I do cost reduce solutions. However, I feel designs should "do no > harm". In other words, the cost reduction might create units that > do not function, but they should never adversely affect the target > vintage equipment. I can assure you that our choice of parts does not harm anything. Unless you actively want to damage the unit (try hot plugging the drive; I still do this all the time), I don't see an issue here. Ask ten architects about how to build a house and I am sure you will get varying results. I would really like to avoid the impression something is broken. It's not, it's working. > * As a fellow enthusiast, I share David's concern over the closed and > guarded nature of the KryoFlux Analyzer. I don't buy the arguments > in the FAQ.

We have two separate products for this, one is KryoFlux with DTC (the disk tool console) that will completely satisfy many private users. The other is our Analyser that will aid a preservationist to verify authenticity and integrity of data ingested. This is aimed at institutions. We might change that in the future due to many requests, however, we still have to figure out to make sure it's understood as an IDE and that you need to understand how disk coding works, otherwise it's useless. Someone not familiar with C++ also won't have much fun with an IDE for that. If you would have to handle all the feedback and questions, you might see this in a different light. It helps discouraging those that have no serious interest, users that really want it usually just contact us and we arrange for something. As a side note: Everyone is free to come up with their own format or do their own Analyser, no one is forced buying into our solution. > * I disagree with Christian's "audit" response.

There's nothing to clear up, and it does not demand a response. I am not aware of any issues, except what I heard via a mailing list from a competitive developer. To me this is not a trusted source of information. I am in contact with our customers directly. As I said in another reply: There is no NDA involved, no contract, nothing. If someone is scared working with a competitive product that maybe has to do with the quality of the product or the demeanour of the person representing it. If I was to damage a project's reputation in public, such created scenario would for sure fit pretty well. > * I agree that you're paying someone not to develop a solution, but to > *NOT* do something else.

That's very well worded and hits the nail on the head. It happens that our "hobby", preserving software, is very costly because it's hard to find a game (or application) in good shape for a decent price these days.

The computer, with the exception of the power supplies, was entirely wire-wrapped.

Well, that is technically a reimplementation of the original Zork for the PDP-10. It is not the same as Zork 1-3, although there are similarities. The original Zork was way too big, when Infocom was founded and they wanted to release Zork for microcomputers. So they split Zork into three parts. Zork 1 is pretty much most of the original Zork, but without parts on the other side of the river (if I remember right). Zork 2 is parts of the other side of the river, and then lots of totally new stuff that does not exist in PDP-10 Zork. Zork 3 is more new stuff that don't exist in PDP-10 Zork, and then also the endgame, which I remember as being pretty much straight off the same. Johnny

Cosmac Elf on breadboard

by jonas＠otter.se

> I wonder, which one is more reliable, wire-wrapping or soldering on a > vero/stripboard? I fancy learning wire wrapping but it's expensive. IIRC wire wrapping is supposed to be more reliable. I certainly remember that it is supposed to be easier to see whether a wrapped joint is good or bad than it is to see whether a soldered joint is good or bad. For a soldered joint to have maximum reliability, among other things the parts to be soldered must be solidly joined before soldering, and not held together by the solder. It is not hard to learn to wire wrap, certainly not with an electrical tool. You more or less just do it. I have never tried wrapping with an unpowered tool. I doubt that would be much more difficult, just harder on your hands. /Jonas

DEC and Osborne Infocom Games

by rickthornquist＠gmail.com

All - Since everybody has been so helpful with my previous queries, I have one more... In 1983/84, DEC came out with their own versions of the Infocom games. They were in DEC's 'Digital Classified Software' line and were for the Rainbow and the DECMate II (and perhaps other systems). They came in large gray sleeves that were different than the usual Infocom packaging. Here's an example: http://yois.if-legends.org/vault.php?id=553 I've been having a heck of a time finding someone who still has these things. I'd very much like to scan the covers to use with the book. If anyone has any of these, I'd appreciate hearing from you. Also, I understand there was a version of Deadline that came with the Osborne. If anyone has this I'd like to hear from them as well. Thanks! - Rick

Zane, Ethan's list of PDP-11 games agrees with mine. Note that the PDP-11 games would have come in Infocom's regular packaging, not the DEC gray sleeve packaging. Stefan, I have a press release which mentions that Infocom was going to do games for the Professional, but I haven't actually found any nor are any listed in their catalogs. - Rick

Discferret broken?

Hi Tony, > I beleive that for the Diskferret I can get sources for everything (of > course soembody might write closed-source softwre to work with it). For > your device, which parts can I get the soruce for, and which can I not > get it for? Are there any file formats involved that are not fully > docuemtned? You get the schematics for the hardware (PDF) and you get the software (binary). Both are free for private, non-commercial usage. You also have access to our own formats, STREAM (as documentation) and IPF (storing the mastering data, created by us; comes as fully documented source and you have the forums with more information as well). That means you have full control over the data you ingested. > No, I think you misunderstood me here. I was talking aobut modifying > the hardware to talk to other types of drives, other devices even. Not > hadnling unusual ewncoding schems on devices (such as flopy drives) > that are supported by the hardware. You can of course modify the hardware you built, or ours, as needed, as you will know where the signals go to. You would however need to work with us, to make us support the new formats. Nevertheless this would mean going beyond what it does now and what it was designed for. > That is correct (well, actually, I can't be sure becuase I don;t know who > is in yor organisation)/ You would for sure have noticed, as the team working on KryoFlux is pretty small (Istv?n, Kieron, two porters (Adam, Alex), me). I still hold on to my opinion that if someone does not know someone else, how can he make statements about them or their work ethic? > That is not what I am doing at all. I feel that money is not a motivator > at all (or at beast a very minor motivator) for good programmers and > designers.

I interpretted your > original message as implying that you clained your device was better than > the Diskferret becuase it was commercial amd you employed commerical > progrmmers. My ecperience suggests that is faulty reasoning. Then why do people get paid in their daytime job? I do like my daytime job, I get paid for it. But how could I afford leaving it for a week, working for free, to make something happen? This has grown beyond a hobby. We already support the formats we ever needed or wanted. We do enjoy doing this, but I don't see why I would assign someone to reverse and implement a format (take Emulator I+II for example), which takes a lot of expertise and manpower, to e.g. support a commercial studio that wants to recover sampling data from their old floppies. These people pay for the unpaid leave from daytime work, we make it happen, and private users enjoy the updates they get for free. I see no evil in this. > I fail to see how an open-source program cna be discontinmued. Ok, let's call it stalled then. I've "heard" the following pretty often: "Look, there's only one main developer, and he's so busy. Maybe if you would donate..?". I think it's really overestimated how many people would have the knowledge to continue with such a project. And how many of them would want to work on this? There aren't many floppy controller projects around apparently. Does that ring a bell? > Does this design inovle any programmed parts (microcontrollers, FPGAs, > etc)? If so, do you relase the code that goes into them? If not, then > presuambly I buy them from you, and toy do 'make a cent from me'. We don't have any. KryoFlux is so versatile and simple by design that all the magic happens in the microcontroller. The firmware is uploaded into RAM each time you use it, you don't even notice. It's included with the software distribution as a firmware.bin. No flashing needed. > > That is preceisely what I don't want or need. I want the information to > solve the problems myself. The reason is simple, you (and your company) > will not be around for ever, waht happens when I have problems in 10 > years time? If this was the case you'd have to write your own software for the board you have, but maybe USB would also not be around anymore to attach the board. I can't look into the future, but you would still be able to access the data ingested because the formats are documented. What I can say is that we don't have plans to let it fade into oblivion, so my understandig is that should we ever decide to not continue with the project, we'd pass it on and / or open it up or even make the latter happen before. We just don't have any intentions doing this now as this would discourage those that can help funding it. We're obviously not as exposed as a top notch browser or similar that would get large donations >from companies, financially, or by assigning engineers to it. As a sidenote: Even if you only had the binary and some STREAM dumps in the future, you could still decide to run it in emulation, like I do today for my Amiga stuff. Why you would want to do this: KryoFlux has a hardware independent, deviceless mode. It is able to "replay" any STREAM file and treat it like the data was coming in from the hardware this very moment. Because of this you can always use the software to transform any STREAM dump to a sector dump of your choice. > >> > Again, you never worked with us.

If you browse the net, you will find many comments on KryoFlux by Phil and maybe none on his solution by me/us. We really try to avoid this.The reason is we don't comment on competitive products as, being professional or not, your view is always biased to some extent. I call doing so bad style. I believe in word of mouth and others doing the comparison. If you'd come to my house and you continuously make fancy statements and suggest things (and have done so in other places in the past) it might happen you get thrown out for not behaving politely. We therefore make use of our householder's rights as needed. This also applies to our Facebook wall. > 2) Is there any truth to the comments about a 'conflict of interests' if > somebody wants to devleop both for your device and the Diskferret? Suggestions like that (the original statement, not your question here) would you get thrown out of my house for sure. Why would any large, big, mighty institution be hindered by us to look at a competitive product? Why would they let us hinder them? If they could get something better that would be completely free, why would they want to take the solution that needs to be paid for? How could I stop them from using publically available sources? This makes no sense. It really helps looking at this >from their point of view. I did not comment on this (and other statements) because I was under the impression that such a statement speaks for itself.

If we could afford doing this because this would be funded somehow, we'd love to give it away for free, with GPL and all kinds of stuff.

Yes that's because both of them will require you to sign a contract that will not allow competing beverages to be sold. You also depend on them because the finance some of your interior. We don't have NDAs, and I don't see why we'd need those. We don't sell by telling stories about someone else, or by hindering someone to look at the competition. We sell because we care, and because we deliver.

programmer for 8755

by kfergason＠gmail.com

Can anyone point me to a reasonably priced programmer for the 8755? Lots of programmers but none seem to program this chip. The one I have found is pretty expensive, as in out of my range ( a couple of Elnec at $1k and more). Was the 8755 that different? Thanks in advance, Kelly

There was this product called RTEM, which allows you to run an RT-11 environment under RSX. But that might not work under P/OS. Besides, that is more complex than the RT-11 runtime system under RSTS/E. >> > ANY GAMES for DEC Professional series ? > I don't remember for certain, but I don't think so, at least not > packaged games that were advertised for the machine.

There might have been a few around the time when P/OS was recently announced, but I doubt they sold many, and I would very much doubt you'd have much luck finding any of those today. There is atleast a Chess program for the windowing system for P/OS that DEC released. Johnny

That said, Infocom never released anything for RSX. They only did an RT-11 version of their games as far as I know. > ANY GAMES for DEC Professional series ? Any? Sure. ZEMU should work just fine under P/OS for one (well, maybe you need to change one thing or two, and recompile it, but it I think that the actual basic task, with no shared libraries and stuff should just work as is as well). Apart from that, I know I saw some weird graphic game for P/OS when I worked at DEC in the 80s, which I've never seen since, but which I'd like to find out more about. If I remember right, it was sortof a grid base, on which you had a robot which you moved around, and which fought others things. I'm very fuzzy on the details, since it was so long ago since I saw it, and I never played it myself, only watched other playing it. Looked cool though. You might find some stuff in the DECUS library, and as long as you are satisfied with text based stuff, almost anything for RSX will work as well. Johnny

DEC Systems available

by snhirsch＠gmail.com

I had someone lined up to take my DEC systems, but it fell through. So, here we go again. Any interest in: Alpha UP2000+ system Large tower case, 2 x 700MHz. 21264 CPU, 512MB of memory. Onboard chipset is succumbing to electro-migration and will not drive more than one bank of memory - thus the 512MB (board can take 2G). Has Tru64 installed on an internal SCSI drive. Alpha PC64 system Medium tower case, 1 x 266Mhz 21164 CPU, 256MB of memory. Has Tru64 installed on internal RAID array. DecStation 5000 Bare-bones system, but worked the last time I fired it up (10+ years ago) VaxStation 3100 I know very little about this unit, but believe it's operational. 2 x Multia These are little mini-format machines using the 21066 CPU @ 166Mhz. I have (somewhere) a 266Mhz. upgrade motherboard also - unknown whether it functions. Other odds and ends: A couple of Alpha motherboards, misc parts. I'm located in Burlington, VT. No reasonable offer refused, I need the space. No, I will not ship them. I don't have the time to deal with packing and/or any associated shipping damage issues. Life is too short. Steve --

SA600 cables

by ethan.dicks＠gmail.com

Hi, Jason, If nobody comes to claim your SA600, I would be interested in a few of the SDI cables if you would take the time to remove them and drop them in a box and mail them (just let me know what you'd want for postage and time). I have a couple of RA70s and I'd love some intracabinet cables to hook them up to a controller. I'd most likely be installing them into a BA123 I have in the dining room - it came to me empty, so I get to build it up however I want. Of course, I hope you find a taker for the whole thing - it's a nice cabinet but too far for me (and I'm more of an H960 guy anyway) -ethan

short DEC racks

by chrise＠pobox.com

Speaking of DEC racks, What is the model number of the short rack that this 11/34 is shown mounted in? http://museum.dyne.org/index.php/File:P5182215.jpg And then just below the RL02 and above the 11/34 is a filler panel. How does that filler panel attach to the rack? I have this same rack, with 11/34 and two RL02 in it and I have the filler panel but no means to attach it to the rack. I can fabricate something but am interested in The Right Way(tm) it was done originally. There is a groved slot on the back of the filler panel that runs the entire width. It appears that this snapped onto a bracket of some sort that was bolted to the rack. Any ideas? Thanks. Chris -- Chris Elmquist

might be landing an HP9K C8000

by spectre＠floodgap.com

I had root to K250 and L3000 PA-RISC systems back in the day (and a C3600 which the biology department used for visualization) and learned to loathe HP/sUX, but I found my pack of 11i CDs in the closet and got nostalgic for the old architecture (wonder what would have happened if Hombre had actually succeeded). I've got a line on a couple C8000 systems at what I consider to be a fair price, fully loaded. While I did a lot of work on the big iron systems, I don't have a lot of knowledge about the workstations. Anyone know any gotchas I should watch for? -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- Let us live!
