Intel μscope 820 from 1978 found - for 8085 microprocessor

by innfoclassics＠gmail.com

I just picked up an intel ?scope 820 with a date code of 1978. It came with the 8085 module and cables. Looks complete with manual but I have not tested it yet, I probably will. It was originally designed as a diagnostic tool for the 8080A. Unfortunately I did not get that module. It is in a plastic black carry case with the manual, 8085 overlay, 8085 module with a ZIF socket for the 8085 and a cable from the module that plugs into the original 8085 socket for the board under test. AC powered. To quote from the manual: The ?scope 820 is most easily described as three instruments combined into a single convenient test instrument. A minicomputer front panel. A microprocessors anayzer. A substitute program memory. I am planning on selling it so if you are interested please make offers. It is very clean and not abused at all. I would bet it has had very low use. This is the first time I have seen one of these even though we used to buy truckloads from intel in the early 1990s. Please contact me off list at paxton.hoag at gmail.com for offers or more information. I supose I should scan the docs, there are only about 35 pages. Paxton Astoria, Oregon USA

reasonable price for a working VT05?

by legalize＠xmission.com

What's a reasonable price for a working VT05 in good working order and cosmetic condition? By "reasonable price" I don't want to hear stories about how you found one for $5 at surplus 10 or more years ago. Its irrelevant. So before you go on about how these things used to be commonplace and cheap/free, let's just inject a little reality into the discussion. They don't come up on ebay with any sort of regular frequency; in several years of running a standard search for DEC terminals, its never come up once. VT52s/VT78s rarely show up anywhere, while VT100s are fairly common. I'm not even aware of many collectors that have one; I know the Wofford Witch project has one, but I don't think Henk in the Netherlands has one (he has a VT55 link, but no VT05). The Computer History Museum appears to have two in its collection, but that's no surprise considering they've received a lot of stuff from Gordon Bell (as I understand it). -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

Emulith V1.2, the ETH Lilith emulator, now also for windows.

by jos.mar＠bluewin.ch

I prepared a new release of Emulith, my emulator for the ETH Lilith hardware. New features : - Usage of the FLTK toolkit instead of of Xlib. - Windows port. - Landscape/portrait modes - normal/reverse video. - file transfer to / from host system - diskimage make & split tool. - partial floppydisk support. - Speed display. Basic CPU emulation remained unchanged and, as before, sourcecode is supplied. Interested parties can now download from my FTP site - The Emulith windows package : ftp://jdreesen.dyndns.org/emulith/emulith_v12.msi - or the Linux package : ftp://jdreesen.dyndns.org/emulith/emulith_v12.tgz - for OS-X : no package yet as I do not own a Mac. However i expect very little issues in porting to the Mac. Volunteer can contact me. and a set of 5 diskimages ftp://jdreesen.dyndns.org/emulith/disk.tar.gz Enjoy, Jos Dreesen

VAX cables for the cost of postage

by jim＠photojim.ca

Hi all, Yesterday I had a failure of my router (it wouldn't reboot after a UPS was reset and it took me basically all day to get it running - but I did get it running!). Since there was a ton of hurry-up-and-wait, I took advantage of the opportunity to clean my basement computer area quite a lot, and made a huge pile of stuff. Most of it isn't of any particular interest to people here (unless you have an itch to own an external Supra modem with a rotating LED display :) ) but I found a box of VAX cables that might well be of interest. Included: A very long (50'?) MMJ to MMJ cable (male on both ends) A fairly long MMJ to DB25 female cable, homemade by someone, connected to a standard DB9/DB25 modem cable. I haven't tested it. This can be the console cable on a VAX (I have one just like it on my VAXstation 4000/60). Two MMJ female to DB25 male cable adapters. You have to self-wire them but the wiring is included. Unopened. Labelled ATI-G25M6-DEC. One MMJ female to DB9 male cable adapter. I inserted the pins on this, but I'm not sure if it's right because it didn't work for me. Hopefully if I did screw it up, you can rewire it easily enough. Two RJ45 female to DB9 male cable adapters, as above, pins uninserted. Two RJ45 female to DB25 male cable adapters, as above, pins uninserted. I think I figured I could put these to use in this project, but I'm not quite sure what I had in mind. :) Obviously, they'd be useful in making inexpensive CAT5-based serial cables. (Presumably they'd be good if you wanted to make a cable for Sparcstations or such, since Sparcs seem to have reverse gender serial ports. I seem to have gender bender adapters for mine though.) A weird DEC cable, DB25 male on one end, and what I think is QBus female on the other (3 rows of pins, 17/16/17 - DB50?). I'm guessing this will be a huge score to someone, just not sure what it goes with. :) Cost: Free. You pay shipping from Canada (to check postage costs, http://www.canadapost.ca, from postal code S4R 1A1). I'll have to formally weigh the package, but I'd guess about 2.5 kg. It's in a standard #10 envelope box that originally held 500 envelopes. To make it fun: - I won't pick a recipient until whenever I check my email first on Sunday (so figure noon CST/1800 UTC as a rough guess, although it might be earlier or later). - If only one person wants them, they win no matter what. :) - Each interested person gets one entry to the random selection. - Canadians preferred, and get an extra entry. But if you're outside Canada and will pay postage, and really, really need this stuff, an exuberant email convincing me of such will make me treat you like you're Canadian. :) (You may also owe me a draught ale from a local establishment, if I ever end up in your city.) (Particularly exuberant Canadians may get three entries, at my discretion.) - Correctly answering the trivia question below gets an extra entry. - Promising to give me an account on a VAX you are running gets you an extra entry. :) (I promise not to abuse it.) (And you don't have to give me an account unless you are awarded these bits, of course.) - Don't answer the trivia question in-list. :) Please reply to me directly, and not on-list. The trivia questions: If you live in Canada, or are a Canadian citizen, answer this one: What is the newest Alberta telephone area code? If you live in the United States, or are an American citizen, answer this one: What state(s) in the United States have land area north of the 49th parallel? If you do not fit into either of those categories, answer this one: Palm trees can be found growing where in Canada? (Hint: the answer is not "indoors", although this may pedantically be true. :) ) Good luck :) Jim

When I connected the power cord, after a few moments there was a loud pop, followed by another before I could pull out the power cord, smoke rose from the PSU. This sounded just like when I had once accidentally made a 110/240 mix-up. The question is, could it be that I had not made the switch to 240 correctly, or could this just be down to the age of the PSU? Regards Rob

8088 vs. 80c88

by les＠hildenbrandt.com

There was also the NEC V20, which was pin for pin compatible with the 8088. It was a CMOS part. There were a few instructions that the V20 executed in fewer clock cycles than the 8088 (multiply comes to mind), causing some motherboard vendors to install a V20, and the sell a 10mhz motherboard as a 12mhz motherboard. The truly great feature of the V20 was the 8080 emulation mode. When a special opcode was executed, the processor switched to 8080 mode, a very fast 8080. I made several CP/M (80) systems using a V20 processor, with a small prom to put the v20 into 8080 mode. I could then switch back into 16 bit mode to implement a ram disk. Les

UK101 update

by lproven＠gmail.com

I have just, this afternoon, finally received the rest of the Compukit UK101 I was talking about last August, which aroused some interest - I received half a dozen direct emails and a few IMs about it, too. I now have the UK101, in a metal case resembling a rather enlarged Dragon32. I also have the original instruction manual, complete with receipt stapled in the back - 26/9/79, I believe. ?252 and change, including VAT, for an 8KB 8-bit machine. :?) I also have a bare (uncased) CRT monitor for it, in its original shipping box. I believe I may also have a demo software cassette tape - I've not yet tried to remove the monitor from its box. My plan is to put these on eBay and donate any proceeds to the Bletchley Park museum. Does this seem reasonable? They will cost a fair amount to post, although I am prepared to do that and I am a reasonably competent packer, not of the "chuck it in a box, add some polystyrene peanuts and hope" variety. Personal collection would be preferable, from South London, but for several potential purchasers I imagine this would not be viable. -- Liam Proven ?

Powering up a 20-year old MicroVAX II

I have just collected a MicroVAX II which has been in storage and has not been powered on for 20 years. This is my first machine of such an age, unfortunately I am not particularly knowledgeable at the electronics level (I studied circuits academically 25+ years ago and can solder a bit, but that is as far as it goes). I know I will need to treat it carefully in order to get it working again. I plan to open it up and make sure I clear out any debris etc, but beyond that I need advice from those with the experience and knowledge that I lack on how to go about powering it up carefully.

Our hobby on MSNBC.com

by evan＠snarc.net

http://www.msnbc.msn.com/id/29264722/ MSNBC today posted a slide show about vintage portables. Myself and CHM curator Chris Garcia are quoted. Also, pictures were supplied by myself, Bill Degnan, and Erik Klein. The slide show is pretty much accurate. It's "the truth" but not necessarily "the whole truth" because of a few other products and technical nuances. Anyway, speaking for myself / MARCH / InfoAge Science Center, we're happy to have the mainstream press.

Randy Cook, TRSDOS, and Datapoint

by frustum＠pacbell.net

It is fairly well known that Randy Cook developed TRSDOS 1.*, 2.1. and 2.2 until he and Tandy had a falling out over the rights to the code. Randy even placed an easter egg that caused his name to be printed out in a copyright message. For TRSDOS 2.2 tandy found the code and patched "RANDY COOK" to read "TANDY CORP" (a three byte difference). Randy developed VTOS, and according to Tim Mann, LDOS was developed by disassembling VTOS 4.0, fixing bugs, and building on top of that. LDOS was eventually licensed by Tandy to be TRSDOS 6.0. OK, the new piece, which I didn't know, was that Randy Cook was an employee of Datapoint when he got the contract to write TRSDOS. He left Datapoint do to consulting work, and everyone assumed he meant on datapoint business. Apparently Datapoint claimed that Randy took DP's code and or "technology" and used that as the basis of TRSDOS. There was a either a lawsuit or a threat of one, but my contact says he wasn't privy to that and so it is hearsay coming from him. I am not familiar with the DP OS (was it really just the Databus language, or was there an OS layer akin to TRSDOS?) Can anybody here compare the two and find threads of similarity?

EPROM erase times and lifespan

by ian_primus＠yahoo.com

Working with EPROMs, one must have an eraser. I built my own a while back, using a germicidal UV lamp tube, a flourescent fixture, a sealed box and a programmable timer. It works well, and I typically can erase an batch of eproms in like three minutes. At least, when I was working primarily with 2732's and 2764's, I could. Now, I've been needing to use higher capacity chips - and these seem to take longer to erase. Five minutes isn't enough for some. AMD 27C010's seem to take closer to ten minutes to erase. My eraser has a drawer that can accept about a foot of eproms (I used a 12" tube). I could probably cram more on there, but I try to keep them centered under the light. So, if I stick a dozen chips on there, of varying sized and types, and 'nuke' them for five minutes, I'll go and blank-check them, and some will be blank, others will be nearly blank (lots of FF's, but some garbage left), and some don't seem affected at all. I've been trying to come up with a correlation between manufacturer and erase time, but it seems to vary. Last time, I nuked four AMD 27C010's that I pulled off of an old LaserJet font cartridge. Three were unaffected and the other was blanked. I worry about leaving the chips in there too long, since I know too much UV can damage them. But at the same time, I wonder about the lifespan of the UV tube - and how many hours it's good for. (I guess I should have checked the package when I bought it...). So, how much UV exposure does it take to damage an EPROM? Is UV exposure cumulative? For example, if I have a chip that's unaffected by five minutes, and I put it back in for another three - is that the same as as running it for 8 minutes total, or do the charges that the UV is supposed to dissapate simply linger? Are CMOS chips harder to erase, taking a longer time than the older parts? -Ian

MITS 1440 Calculator

by billdeg＠degnanco.com

Does anyone have a MITS 1440 Calculator? I am looking for someone who either has a non-working unit, or one that needs some sort of attention, or someone who would be trusting enough to loan me and a friend their working unit to carefully swap the ROM chips and see which one is bad. I think the risk of damaging a good chip is low, but paranoid attention will be made to avoid accidents. I have been told that the input chip is OK, and the output chip is OK. The control chip seems OK. Most likely the program ROM chip is bad, but it could possibly be the registers or ALU. More likely the ALU than the registers chip.If anyone is interested in this project, feel free to drop me a line. See July 1973 Radio Electronics for more info. Bill D

Reposting due to the resounding lack of response and the possibility that something went wrong with the list right after I posted the original... I can buy or trade but I would prefer to trade. I have a large collection of S-100 cards and some other goodies to work a trade with. If it has the CUTTER ROM, all the better. If not, I can burn a 2708 (and I'll probably post a "Wanted: CUTTER ROM dump" message). Thanks, Bill Sudbrink PS...

8088 vs. 80c88

by steven.alan.canning＠verizon.net

Intel does some squirrelly crap but I can assure you that unless it says 80C88 it is NMOS ( the -2 version of the 8088 is Enhanced NMOS or HMOS, but still not CMOS ). CMOS is not necessarily slow either, but at higher frequencies it looses it's low power advantage. We used SOS ( Silicon On Sapphire ) 1802s on spacecraft because of the low power, and the SOS makes it much less static sensitive and Radiation Hardened. Intel screwed us when they stepped the 8031 to CMOS ( 80C31 ) as they forgot to mention the multiple pages of errata of things that didn't work right, like Power on Reset and Interrupts..... Best regards, Steven ----- Original Message ----- From: "Chris M" <chrism3667 at yahoo.com> To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Sent: Friday, February 13, 2009 8:10 AM Subject: Re: 8088 vs. 80c88 regardless, and be sure I am no expert on semiconductor manufacturing, I'd be surprised to find out that all 8088's were CMOS after a certain date. The 80c88's were used mostly in small laptops, no? (small being anything smaller then that Zenith big honker, w/the shocking blue display. It used a *real* 8088 IINM).

Saving TU-58 Tapes

by jhfinedp3k＠compsys.to

I just received a number of TU-58 tapes. Most seem to have VAX software. Is a list of the contents of such tapes available somewhere? I want to save the files before I use them for RT-11. I have seen such a collection of VAX software before and I presume that I am not the only person to save the files. So if this has already been done, it will not be necessary to repeat the exercise. I attempted to look at bitsavers, but there does not seem to be anything much there in the way of software for the VAX. I assume that since there are hobby licenses for the VAX that all of the software is also available. By the way, the dates on the files are 1983 to 1985. Some of the contents are: VAX/VMS 3.4 FORTRAN C PASCAL Are these tapes useful? How are the files saved? Can the files be easily saved using RT-11? What is the best media to save the files? Probably the only reasonable method with RT-11 is to save all 512 blocks of the TU-58 tape as an image so that a VAX/VMS system can easily ATTACH the file as a TU-58 tape drive under SIMH. Sincerely yours, Jerome Fine

Altos 8000-2 booting, SD> DD (CPM)

by g-wright＠att.net

as long as I'm on the Altos thread. I'm trying to make some disks for another list member for the 8000-8200 Z-80 based machines. Both of my systems have floppy disk boot or write problems. So I decided to look into the easier machine which it a 8000-2. basic Z-80 , 1791 FDC and 2, 8" SSDD floppies. The machine will boot a single density CPM disk, read and format a SD disk, but dies if a DD disk is either inserted for boot or the format program on the SD disk is told to format a DD disk. These all have SD Boot tracks, then have to switch to DD, if formated in DD. I have the wiring diagrams and there is a "EN DD" coming off the PIO chip and goes to the 1791 chip, that never changes state. I would believe it would have a floppy density code on the 1st track to tell the OS what the remaining tracks are ??? (just a guess) I know the disks are OK, they can be read in another machine. ( just not copied.). i have looked at the data lines on the PIO chip and have replaced it just in case. I have scoped the started up circuit which also has the "EN DD" tied to it. (input) The software can only be copied by another Altos due to the disk layout. The boot ROM could be damaged?? but not knowing what it should read, its hard to guess. Can't be much there just a 2708. Anyone have a 8200-2 that can read the ROM on, or any ideas. The manual is on Bitsavers under Altos, ACS8000 users manual. The motherboard is a 8100 series (double density) Has 8000 SD, 8100 DD and 8200 in the manual. - jerry Jerry Wright g-wright at att.net

Altos & M/PM manuals available

by silent700＠gmail.com

I have a large box of Altos materials here that I would like to find a home for. About half of it is standard bound books, which will go first. The remainder is ringbound and I am going to attempt to scan them. In addition to manuals there is a lot of dealer sales material, including about a dozen issues of the monthly sales newsletter "ALTOgether." The first lot includes manuals for the Altos 486 (which was really an 80186,) Altos 586/986, Altos XENIX, and a few for the M/PM-II and MPM-86 operating systems. A couple books are a bit warped from sitting in a box too long, but they're all in pretty good shape otherwise. All in all about 16lbs of books. Free for the cost of shipping (Media Mail rate shouldn't be too bad) from 60074. -j

Tektronix 4225 -- is it an X terminal?

by legalize＠xmission.com

See ebay item # 360132413754 That listing just includes the base unit, but thankfully has closeup pictures of the connectors on the back. It looks like it takes AUI ethernet or RS-232 and outputs RGB video. Anyone familiar with these puppies?

Any have a CMD CQD-200/M manual?

by toby＠coreware.co.uk

Hi, Has anyone by change got a manual for a CQD-200/M (QBUS SCSI controller). The device is pretty similar to the CQD-220/M, which has a pdf on bitsavers, but jumpers are alas not the same and I just want to check I've got everything set correctly and enable its bootstrap I've fired it up on my PDP-11/23+ with an RZ27 disk and I can indeed access it via RT-11 but I only get a 32MB (65K blocks) disk after an initialize. Does RT-11 have a 65K block limit on a disk? Thanks, Toby -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Source for 12.44Mhz crystals?

by derschjo＠mail.msu.edu

Hey all -- While I'm waiting for other parts to arrive for my Tek project... anyone know where to find 12.44Mhz crystals? I acquired an old SSM VB1B video card (with an amazing 64 cols by 16 rows display capability!) that was only mostly-assembled, and the crystal is missing. According to the manual (http://www.classiccmp.org/dunfield/s100c/ssm/vb1b.pdf), it's a 12.44 Mhz part but I can't for the life of me find one anywhere -- even my Google searches mostly return links to the VB1B manual :). (And while we're at it -- my Tek project needs a pair of 39M-ohm resistors... anyone know where to find _these_? I know I can hack one up by putting a few others in series, but it's quite a mess...) Thanks, Josh

I was cleaning out a box of PCMCIA cards and found a gray thin pcmcia memory card with no markings on it. I believe it was used to load some of the HSJs when we got updates. If anyone wants it, I'll drop it in the post (US or Int'l) for the cost of shipping.

Datasheet for ICT 27CX321 EPROM?

by ian_primus＠yahoo.com

I've got a handfull of these things that I've been trying to use. My programmer supports them, and I was hoping that they would have the same pinout as a 2732. At the moment, I'm not so sure. So far, I've had three of these chips in the eraser for a good 45 minutes total. If I set the programmer to the ICT 27CX321, it won't blank check - although reading it in and examining the data produces something composed mostly FF's - though not entirely. If I set the programmer to a generic 2732, it passes blank check. I haven't tried programming one yet - although I suppose I could try to fill one with zeroes. So, I take it that these things have a different pinout? I can't find any data on these. Any help would be appreciated. -Ian

Nicolet 660

by aek＠bitsavers.org

> test equipment seems to be a poorly covered area in the museum > and archive world. I was thinking about this some more last night, and there is little activity preserving the software for test equipment. Brokers keep the manuals and the hardware, but rarely keep the software to make it work. For example, the Biomation CLAS 9000 logic analyzer had no built in user interface; it was a SCSI periperial connected to a Macintosh. They didn't document the protocol to talk to it, so it is a rather large boat anchor without a Mac and the software to talk to it. Then, there are all the PC instruments that had custom cards and software to talk to their widget. The parts are separated, and no one saves the card inside the PC or the software to make it work.

"Infoshare" or OEM Netware 1.0? was Re: Novell 68K file server

by chrism3667＠yahoo.com

I have to assume then that the software that ran on the 3*'s was a later development then the stuff that ran on the Televideo Personal Mini series (80286 based). Dubbed Infoshare, which was an OEM release of early Netware (and I am looking for it). Other boxes that come to mind are the Northstar Dimension (80186), and an Altos box. Not sure what they ran though. There was a PM/286 too, which ran a later version of Infoshare IINM. ?Anyone familiar w/the Burroughs '286 boxes that also weren't MS-DOS based? ?Sorry didn't mean to *help* hijack the thread. That is a very interesting piece. The peculiar 68k stuff is far and away the rarer birds though, sadly snifful.

Dr. Dobbs to cease?

by shoppa＠trailing-edge.com

Dr. Dobbs was pretty cool... up until the IBM PC came out and dominated everything. By the mid 80's all the Dr. Dobbs articles were the-latest-TSR-to-do-something-in-MSDOS and it wasn't really worth the effort for me to even look for something interesting in it. That may have marked my turning point towards classic computing, in fact :-). Tim.

Ah yes, the era of the 3Server is forever seared into my brain; my first *real* job in the computer business involved the care and feeding of several generations of these beasties. The Original 3Server (about the same vintage as the Novell unit pictured earlier) used an 80188 and a heavily modified version of MS-DOS. It used an early SCSI implementation, which was closer to SASI, to attach MFM disks and QIC tapes via Adaptec bridge boards. Because there were neither video nor ISA bus, there was more room for contiguous DOS memory; something over 700k, which pertty cool at the time. They originally were equipped with 30MB drives, but then the 3Server70 had an 80Mb (unformatted) unit by Vertex. These early boxes had the (optional) QIC tape in an external box; the 3Server3 introduced in 1986 (IIRC) had disk and tape in one box; in addition the 3Server3 could be interfaced with appletalk, and also sported the then-new LIM memory used to speed up the operating system. These 80188 systems all used either 3+Share or EtherSeries NOS's for basic drive sharing. IN addition, 3+Mail, 3+Route (for routing e-mail between sites), 3+Backup and other network applications were supported under the 3+Share NOS (in <1Mb RAM). These were followed by the 3S400 & 3S500 machines, which are not interesing as they are little more than stock ISA 80386 machines running at 16MHz. These guys could run 3+Share, or 3+Open (a.k.a. OS/2 LanMan as pointed out above). ISTR that they added TCP/IP late in that products life. Then Novell took over the world and all of the above 'stuff' died in obscurity. It was at this point where I learned in my life that I had a knack for picking losers. I need a stiff drink now . . . . ____________________________________________________________ Wasting money?

Alignment disks, and the creation thereof

by ian_primus＠yahoo.com

I've been reading the now increasingly mistitled thread on alignment disks, and it's gotten me thinking. What IS required to make alignment disks? I've always aligned malfunctioning floppy drives "the wrong way", using a known good disk - or an original software disk. On the Commodore 64 (and most systems, really), you can get the drives working well enough like this, but as others have pointed out, it's not the "right way". I just don't have any alignment disks. "Good enough" is much better than "not at all", and I don't mess with the drive alignment unless I have to. I'd love to be able to align drives properly though. And that requires an alignment disk. There are different kinds of alignment disks too - analog and digital, ones that are intended to be used with a special program on a particular computer, and those intended to be used with a scope. With today's modern machining technology, it should definitely be possible to create a system to write new alignment disks. Starting with a standard floppy drive, you could replace the stepper drive with something more precise and controllable. Then, you have to somehow accurately calibrate this whole thing. Is there a document out there that describes the track layout of a standard (say, 5 1/4" 48tpi, 40 track) diskette? There has to be a spec, one that describes exactly the distance between tracks, the width of a track, and the distance from the center hub to the beginning of the first track. If you had that information, and precision measurement tools, one could set up and calibrate the drive to spec. Then, of course, there needs to be a controller for the thing, a computer interface to control the precise positioning of the head, as well as being able to read/write to the disk. It's possible. It's beyond the equipment and tools at my disposal, but it's definitely doable for a hobbyist who has access to a machine shop and good tools. Anyone out there a machinist? :) -Ian

Need Fuji M2312 info

by mcguire＠neurotica.com

Hi folks. Does anyone have an electronic copy of the manual for the Fujitsu M2312 SMD drive? I need to configure two of them for use on an Emulex SC72 controller and I need to know how to set the DIP switches. Lacking an electronic copy, does anyone have a paper copy, and if so, would you be willing to scan or type in the relevant pages? -Dave -- Dave McGuire Port Charlotte, FL

Two RK05J's + PDP11/34 Offered

by fsmith＠ladylinux.com

Hi, These are located Near Toronto Canada and will preferably be picked up. Any shipping will have to be arraigned by the buyer. I purchased these from a gentleman off E-Pay a few years back and never came around to getting shipping to the USA sorted. One RK05 is missing the face plate but powers up fine and the other is in great shape and comes ready when a DECpack is installed. The 11/34 powers up fine and seems to be in good shape. Really I would rather sell these to someone here rather than go the E-Pay route. I paid some decent cash for them and would just like to get as much of that back as possible. Trade offers for vintage audio equipment will be considered. Inquire off list please.

Great Find by the Wife

by john_keys＠att.net

Today my wife and daughter were at Goodwill and found a Atari Portfolio in the box with a working Portfolio in it, a 32MB memory card, smart parallel interface, and a file manager/tutorial card with all the manuals/papers for everything. Cost was only $1 plus tax. That got me a few other goodies too. Life is good. John K.

Problems installing Solaris 10 10/08 on Sun Ultra 30

by alexandre.laguejacques＠gmail.com

Hello all, Please, no flames if you don't consider an Ultra 30 a "classic computer". :-) At 300 MHz, it's not terribly recent either. My system is a Sun Ultra 30, 300 MHz, 1.7 GB RAM and a 16 GB hard disk. Trying to install Solaris 10 10/08. The initial installation reboots after having copied Solaris to the hard disk and the machine freezes at the line "creating new dsa pair"... I've given it a few hours on several occasions with no success. Note that NetBSD works just fine on this system and that I encountered the same DSA key problem with Solaris 10 4/08. Also, I had had significant trouble installing NetBSD initially because of defective memory (the system would freeze at "boot cdrom" until I removed the offending items). Once the problem with the memory was resolved, the NetBSD installation worked perfectly and I presume that the remaining sticks are fine. Finally "boot -k" (after the Solaris installation has copied Solaris to the hard disk) yields no further details. - Alex

archiving (was Re: Nicolet 660)

by aek＠bitsavers.org

> I get the impression > that there is NO effort by any official archive to collect manuals and > such Stanford Library special collections have the Ampex and Apple archives, which contain manuals. The Charles Babbage Institute at the University of Minnesota as well as the institution I work for (The Computer History Museum) have extensive manual collections. Test equipment is out of the scope of CBI or CHM's collecting scope, though. > test equipment seems to be a poorly covered area in the museum > and archive world. But seems to be getting coverage from private collectors and some companies (like Agilent). If there were significant numbers of people from universities at this conference, you should have noticed that they have problems enough trying to fund the archiving of the contents that their own institutions, without actively collecting on the outside. This reminds me of a friend from years ago that was a fan of steam traction engines. No "official" institution collected documentation on them, but there were preservation organizations that kept their own archives. The problem, of course, is if the society is disbanded without a long-term recipient for the material collected.

Ideas for disposing of entire collection

by robert.stek＠gmail.com

I am happy to report that my large S-100 collection is going to a single person, both to expand his own collection and for eventual sale to other collectors. [sigh!] If only I had another 400 sq ft and another 40 hours/week. Thanks to everyone who responded with some good ideas (and requests!). The important thing to me is that it is all going to someone who will not be cutting off connectors to melt down for gold! I'm sure that he will let list members know what he has available in the next few months. Bob Stek Former Saver of Lost Sols

Nicolet 660

by charlesmorris800＠centurytel.net

> Hmm. Yeah, I've never heard of Nicolet either. Interesting find! In the early 80's the company I worked for had a very neat little portable audio-range FFT spectrum analyzer called the "Mini-Ubiquitous". Always wanted one. In '92 the USAF transferred me to Dayton OH (home of Mendelson's Surplus) and they had one sitting in the pile of instruments for quite some time... but they wanted $400 for it. So they are hardly "ubiquitous" since I've only spotted two :) -Charles ps anyway I acquired an HP 3580A for $100 at the Hamvention which was an easy fix... anyone know where I can get some decent knobs for it?

My reply - Boot Disk Needed for Kaypro 2X

by FJGJR1＠aol.com

Larry, >From the info you gave and the info I have, I offer the following. You need a "CP / M boot disk", not an MS-DOS boot disk for the Kaypro 2X - either 2.2H or 2.2G. CP / M. Your mainboard shoud be an 81-294 [underneath board usually under serial port] and the ROM version should be 81-292-A - white label on the about 1" size chip at U47. But since you have a Turbo upgrade, the chip may have just a Turbo designation. Any manufacturer designation and revision / year, etc. could also be important. Also check what the U43 chip label is - usually again a white label on a 1" size chip. There is also a Kaypro 2X / MTC version. How do you really know it is a 2X - cover designation, back plate designation, etc.?

House cleaning!

by derschjo＠mail.msu.edu

So I've amassed way too much stuff lately and I have a lot of cool stuff that I never touch anymore, so I'm thinning out my collection a bit to free up some space. Smallish stuff I'll ship, but the large stuff is local pick-up only. (Seattle, WA area). Happy to drive out a ways to meet you if it helps. Make an offer -- no reasonable offer refused. Stuff that doesn't get claimed 'll probably end up on eBay eventually. Thanks! Josh Monitors: --------- - Amdek Color II - Works. - Gateway 2000, 15" Vivitron (does 1280x1024, actually a nice SVGA...) - Ball 9" CRT Terminals: ---------- - Intertec InterTube II - Does not work. Makes horrible hissing/screeching on power-up. Dirty, but will clean up. - Beehive SuperBee - No keyboard. Needs work. Ugly looking on the outside, but very clean inside, given how old it is. - Wang terminal - Cannot find model on case, believe it to be part of an old Wang word-processing system. Built like a tank. Computers: ---------- - Compaq Portable III - Worked the last time I powered it up. Hard drive, 5.25" floppy drive. - Compaq Portable 386 - Also works. 2MB ram, hard drive. Carrying case (travel in style!) - Dell Optiplex, Dual PPro/w P2-Overdrive. No HD, I have RAM somewhere. - HP 9000/236 - W/Monitor. Works, but floppy controller reports errors on startup. - HP 9826 - Was working, but monitor no longer powers up. - Mac Plus - Not working. - Pet 2001 (32k) - Works - CBM 8032 - Works, PCB is a bit hacked up, but works. - ComputerVision CADDStation 32 - Neat old Sun3-based machine I inherited awhile back. Really heavy, no I will not ship. Just the machine, none of the various CAD-related input devices. Mostly working -- CPU board needs repair (but it's just a rebadged Sun3 VME processor board so it's not impossible to find parts...) SGI Personal Iris 4D/35 + Iris File. No RAM, alas. Chassis has a bit of rust, but is otherwise solid. TRS-80 Model II + external 8" drive box (w/2 drives installed). Works, a bit worn. (Have not tested all the drives.) Laptops: -------- A goodish stack of older laptops. 386, 486, and Pentium. Ask for details. Take one, take all... take as many as you want! Misc: ----- CBM 2031 5.25" floppy drive - works CBM 4040 dual 5.25" drive - does not work. DECServer 200/MC. Appears to work. Never took the time to set up a machine with LAT, etc... to try it out. HP 1200B Oscilloscope. Rack mountable, Dual trace. Needs some repair (trace does not scan across the screen correctly.)

KEEP annoucement

by aek＠bitsavers.org

From another mailing list: > I am glad to announce, that a major European research project, which is related to the preservation of complex digital artefacts, has just started. KEEP (Keeping Emulation Environments Portable) is funded by the European Community with 3,15 Mio. Euro will go on from now for three years. Aim of the project is to utilize the preservation tools, which are mainly created in the gamer community, for a broader range of users and purposes. The impact of the project lies also in the structure of the consortium itself: for the first time traditional memory institutions like the national libraries of France, Germany and Netherlands and researchers with a background in humanitities (University of Portsmouth) come together with organisations specialized in games resp. their preservation (Computer Game Museum, European Games Developer Federation ) within a common research effort in such a scale. I am pretty sure, that we will be able to boost the awareness of the need to preserve the gaming culture on that basis and of course provide concrete preservation tools and interfaces to do the job. > > More details about the project can be found here: > http://www.computerspielemuseum.de/index.php?lg=en&main=News&site=02:00:00&…

8048 Intel programming languages

How about this: Did they ever >release any sort of languages for the IMSAI 8048 board? You have an Imp48???? First if you have a manual I'd appreciate a copy, I've been looking for 28 years for one! Yes, I have one too, I know the general circuit for mine by reverse engineering it and I do use it for playing. As to languages for 8048, IMSAI never did. The concept of a higher level language for a board with 1K of program space is only a thing you hear lately. One reason is the limited stack and ram/romspace of the 8048 really does require the efficientcy of assembler. It's possile to create some varient of a tiny micro basic but then it has to fit in 1K and also any program in the same 1k. If you working with 8048/9 off that board more space is possible but remember the ability to address ram without some banking scheme is limited to 256 bytes. I'd say keep looking though as I've likely missed a few. I'm sure it's possible to tweak the code generator in SDCC to do 8048 and it's rare anyone uses more than 4k. But the compiler logic to do the bank switch is likely insane since interrupts are only handled in the low memory page. There are all sorts of cross assemblers out there.

Need Fuji M2312 info (retraction)

by tiggerlasv＠aim.com

Sorry about that -- I no sooner hit "send", when I realized that I transposed numbers on the Fujitsu model number. I don't know how close the model numbers are; perhaps you can extrapolate the sector settings based on the 2321 info. . .

Need Fuji M2312 info

by tiggerlasv＠aim.com

Howdy ! I believe the details you are looking for can be found here: http://stason.org/TULARC/pc/hard-drives-hdd/fujitsu/M2321K-MB-8-0-FH-SMD.ht… Scroll down; everything is there. That site has many different models. . . Would be nice if that were posted on bitsavers or manx. . .

Yes, I know all about those drives, and I have one that it is "semi-operational". I worked on these in 1979 and had them connected to a 6800 system. While they worked most of the time, they were a bit picky. They needed 36 volt power supplies as well as others. The controller provided actually did work. The early drives had a secondary board that eventually was replaced with an LSI chip. Their main problem was that they were a bit (well actually more than that) temperamental. The drives themselves were only 10Mbyte goodies, and used embedded servos with on-track sparing. The disks themselves were "cut-down" from 14 inch media (like 2315's). Thankfully I eventually replaced these with SMD drives, then 5 1/4 drives with the Xebec 1410 controller (SASI). All on a 6800! Fun in the early 80's

Reply - Re: Boot Disk Needed for Kaypro 2X

by FJGJR1＠aol.com

Larry, Go to _www.vintage-computer.com_ (http://www.vintage-computer.com) and do a search on that topic. Also, contact "Sharkonwheels" there - again do a search - he posts a lot. He is into the Kaypros "after" 1983 versions - i.e. the "2X's", I am into the 1983 versions. Looks like it may have been upgraded with the Turbo. I believe such upgrades are still available for the post 1983 versions - Advent might be a search word to use. Shark will know. He even sells modified Kaypros of that era. Getting the right boot disk for the specific Kaypro you have is critical - many do not understand this - today you need Windows - there are not very many main options. Kaypro had about 15 - 20 different versions before they went bankrupt. Also, in those hectic times, many "unofficial' modifications were made that may not have been documented, by Kaypro and previous owners of such computers. Modifications and upgrades were very common in order to try to keep them running efficiently, until the inevitable change to windows, after we all invested so much in those systems, especially our time! Sometimes you just have to take the top off and look around, especially at chips at U43 and U47. Please post your results on that site so others can benefit. You can check my site out - _www.kayprosts.org_ (http://www.kayprosts.org) - under the folder "special" for a draft of my book on computers of that era and a 2008 Kaypro calendar I did - lots of pictures of my 6 1983 Kaypros modified to Kaypro " 8 ' 's. All the best. Frank In a message dated 2/10/2009 11:34:45 A.M. Eastern Standard Time, laptoplarry at gmail.com writes: The boot disk I have is looking for Turbo ROM.

Alignment disks, and the creation thereof

by julianskidmore＠yahoo.com

Hi folks, > I suppose someone might magic up a way of creating DIY floppies from > scratch in a home lab, but I'm not holding my breath. http://www.madehow.com/Volume-1/Floppy-Disk.html http://www.mylarstoreonline.com/25ft.html I think you want the 3mil type (assuming 3mil means 0.003", my knowledge of non-metric units is getting rusty ;-) ) With this and some iron oxide (from China?) you have the makings of a floppy disk - you just need a jacket and liner; something to polish it all with and a pair of scissors (kidding). -cheers from Julz @p

Anyone have a line on batteries for the NLS

For the NLS 'scopes the battery is between the charge source and the scope power supply so if it's open (badly sulfated as the battery is lead acid gell type) the PS has to carry the load. It's only a charger. if you substitute a larger charger then you find the charge circuit does not have the capacity to start the unit (initial surge current). >Assuming the battery pack is just a battery (that is, no 'battery >management' circuitry), you can often run the unit from a bench power >supply connected to the battery wires _with the battery disconnected_. Of >course this assuems you have a suitable PSU... The pack in this case is just 3 2v cells and the "management" is the charge circuit on the rear board. In this case (nls miniscopes) a 6V PS can substitute for the battery at less tha 1A (must be connected to the ground and +6V termianls of the battery connection point internally). Only if the battery is removed first. Note that is the battery has failed (usually sulfated from not being kept charged) they tend to build corrosion around the terminal, they are best removed and recycled as any gelled lead acid battery should be. Since I use my miniscopes intermittently I've long since removed the battery and disconnected the internal charge circuit (pull the fuse). The battery area has a small board inserted to allow it to accept any voltage from 9 to 30V and run from that. Since I have a number of small 12V gell cells that fit nicely in the probe pocket of the carry case this proves more useful and maintainable. The change is completely reverseable and the ability to use a larger and longer lasting 12V battery as source is very handy. The NLS is somewhat unique as it uses a lead acid type rather than NiCd, Nimh, lithium or even common dry cells. In an emergency I have run it off 4 'D" sized alkaline cells in an external holder for many hours. Allison
