Hello, all: I wanted to drop a quick note to the list to let everyone know that I've just posted a "dot 10" release of the Altair32 Emulator. Normally I wouldn't release a minor revision such as this, but a heavy user of the emulator has found some minor errors in the disk image code that causes corruption of the disk images after repeated use of the image. He also found an error in the binary file handling code that, upon looking at the changes history, has been around since version my first version. So, if anyone has been using version 2.3, please download and begin using version 2.30.10. Thanks.

I hate to do this, but...FA Osborne 1 with orig. software

by nerdware＠laidbak.com

It's time to thin the herd.... I don't have time for the old computers anymore, so I'll be clearing out the rest of my collection over the next couple of weeks. Last time I tried to offer stuff here with "make an offer", I got no responses, so I went the epay route this time. If you're interested, it's an original beige case model. It lights up, but drive access seems to be down. Has original disks in original box, including CP/M, CP/M utilities, MS BASIC, Supercalc, and Wordstar with the keyboard overlay. AC cord cover is intact. Aside >from yellowing, it's in great shape. The auction is at:http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=20479715 73&rd=1 Thanks.

Cromemco 64KZ Info Needed

by mhscc＠canada.com

The 64KZ is organized as two 32K Blocks (not 16); the A15 switches control whether that block is in the lower or upper half of the 64K range. Reset out disables that block after a reset to allow the boot ROM to use that space on power up. Override & DMA are only relevant for DMA operations. Bank switching is done by outputting a byte to 40H (this address is set by a jumper block/PROM): bit 0 = bank 0, etc., and each block's bank(s) are of course set with SW2 & SW3. Good luck; I've got a manual somewhere that I could scan if you haven't already gotten one elsewhere, but probably not this weekend. Email me off-list if I can help. m -----------------Original Message---------------- From: "Mike Davis" <ipscone(a)msdsite.com> To: cctalk(a)classiccmp.org Date: Wed, 21 Aug 2002 21:48:17 -0700 Subject: Cromemco 64KZ Info Needed Reply-To: cctalk(a)classiccmp.org Hope this is not a duplicate. The first one did not show up. I have just obtained a Cromemco 64KZ board. This has 64K of RAM and I'd like to test this out this weekend. Unfortunately, I don't have any documentation. There are 4 banks of RAM (16K x 8) Each bank is labeled "page0", "page1", "page2" and "page3". There are also 3 8-pin dip switches: I have a couple of photos at: http://www.msdsite.com/vcomp/cromemco/photos.html Since this is a 64K board and since there is other memory in my system. I'm hoping this allows some sort of bank switching. But without docs, I don't know how to use it. I assume the Bank A/B allow setting which bank a particular 16K might reside but am not sure. And the address lines of A15, A14 are a mystery. Is there a way to switch banks by writing to an I/O port? Location? Can any of you help with an explanation how this works and how I might use the switches?

Intergraph clipper rescue

by roosmcd＠dds.nl

Hello, Today a rescued a load of clipper stuff. I've just finished taking everything out of the car and it consists of the following items: Interpro 125 + monitor 4x Intergraph 2000 (I already had one of thse myself); I opened one and they seem to have C300 clipper processors. 2 other monitors keyboards and mice 2 A3 tablets lots and lots of cables stack of documentation (looks complete to me) and last a lot software. I've got boot floppies, cd's, Informix and Microstation xx, all with licenses. I'm now trying to get things running. I've booted the Interpro 125, but had no succes with the workstations. Will these work with the same monitor as the Interpro 125? The other monitors are still standing downstairs :(. I tried connecting the 125 monitor to a workstation, but didn't get a picture. Or maybe I should sort out the manuals first and look there... I'm only planning to keep the Interpro 125 and one workstation, so if anyone is interested in obtaining a machine/Clix, please mail me. I got these for free, so you can have them for shipping cost only (from .nl). greetings, Michiel ps. Another question, what kind of memory do these machines take? It looks like standard 30-pins simms, Is this correct?

Wanted: Cromemco assistance

by mhscc＠canada.com

Congratulations! A fine box indeed. I might be able to help ya; I scrapped a pile of Cromemco stuff and Dan Cohoe's name is on most of what's left, but I believe there is most of a spare Z-2 cabinet left over, including the front panel (the version without floppy drive cutouts). But an S-100 chassis (especially the Z-2) is only that; as far as disk drives & OSs, that would all depend on what cards are in there. FWIW, I do have copies of 11-(Z80), 20-(68000) and 30/31-(68010) series Cromix, CDOS (their version of CP/M), and various utilities and languages. Also some cards & lots of manuals, at least until Dan cleans me out.

Hi Cameron, > > Rodime had a deservedly bad name, but in the interest of fairness, my > Mac Plus has a Rodime 20MB drive connected to it which has run > 100% for > a very long time. I've a pair of 40mb Rodime drives here (RLL'd out to 67mb) that have been running since 1988 - almost non-stop (on one of the BBS machines). One is a little noisy (always has been), but apart from that they are extremely reliable - let's see they must be at least 7 or 8 years past their "use by" date ? No dead sectors, no power up sticking - the only drive older is a 20mb Seagate ST225 that has been in use (sporadically) since oooohhh 86 or 87. Got plenty of spare ones though :-) Wonder what a hundred or so ST225's would go for on eBay :-) cheers, Lance ---------------- Powered by telstra.com

The PMOS doesn't pull down vary hard. It is usually in the order of a milliamp. It is hardly enough to cause problems for a signal diode that are usually rated at 50 ma. It might be open drain but even so, the pulldown is usually small enough that, to interface to TTL ( that has an effective pull up on it's input ), one has to add more pull down to get it to work well. This is why the resistor. The diode is just to limit the swing. The voltage is then across the resistor and any small pull of the PMOS. The pulldown of the PMOS is a constant current type so it can be clamped without doing damage.

Bad Drives

by jpl15＠panix.com

I was working for a rat-hole computer store when the Kaypro 10s debuted - Kaypro made a deal with Lal Tandon to buy 10MB drives made (IIRC) in Mother India - at any rate the 10s of that vintage had about an 80% DOA rate. You could (and I did, on numerous occasions) show up in the reception area of Kaypro in San Diego lugging a 10, and someone would bring you out a new one on a box, that had been burned-in... no questions asked, just "Sorry for the inconveience, here's a new one under warranty." They had a big tent set up in the parking lot complete with mobile air conditioners to handle all the re-work. It was truly a nightmare. These were from the batch where you could pay extra to have your unit 'personalized': it was supposed to be a mark of distinction that you had an expensive portable computer with your name tastefully inlaid. What happened in practice was the last guy on the production line took one of those vibrating-carbide-stylus things and scrawled whatever was on the invoice all over the back plate - never mind the paint or the silk-screening.... it's funny, now... AND - my 1988 Mac SE30 came with a CMS internal HD, complete with a nice copy of nVir - courtesy of a disgruntled quality-control tech at CMS. It would replicate itself at intervals and grab the speaker and say "Don't Panic" in that early MacInTalk voice. Then at some point it would say "Now Panic!" and trash your HD. Pretty tame as virii go today, back then the store I bought it from had to shut down for two days while they disinfected every machine and disk in the joint. Mine included. And I just recently found the original invoice for that machine, which looks down on me now from the shelf where it sits in snug reirement; it used to run my music studio. Cheers John

This is generally fixed with a pull down resistor and/or a diode to limit the negative travel. Some TTL can tolerate some negative on the input, most CMOS can't ( I think the 4049 can though ).

First, straighten the pins so they don't bow outwards. This is the most important step. For some reason that I've never figured out, the tension on the pins causes then to want to be out of the sockets, even though, you'd think it would tend to hold them in. The second thing will help for good contact and that is to use a silicon grease, like Dow Corning #4, on the pin leads. I've been told the Permatex dielectric grease is the same thing and I've used a product call Silglyde. Although, it is called a grease, it has poor lubrication properties but it will cause parts the come out with spring tension to come out easier, I've not seen problems with the leads straightened and the part weight being the only factor.

PowerUser external SCSI HD

by mythtech＠mac.com

>> after I got burned on the >> Jasmine/Rodime fiasco >Don't think I ever heard about that - might be before my time. Care to >elaborate? Once upon a time, back in the early Mac days... there was a drive manufacturer called Jasmine. They made about the best damn drives money could buy. Every time there was a review of drives, Jasmine came out on top. And their prices were good as well. Well, Jasmine, like most external drive makers, didn't actually made the drives inside their boxes, they bought from other makers, stuck them in pretty cases, wrote formatting/partitioning software, and sold them under their name. Jasmine bought internals from a number of companies, Quantum, Segate, Rodime, and others. Well, one day, Rodime shipped Jasmine an entire lot of defective drives (and not a small lot, like thousands and thousands of them). Jasmine, sold these off, after packing them up, and doing their basic burn in. But the defects wouldn't show up until the drives had been run for some time... then Kapow... drive would die. Of course, this would happen about 60 days into good use, right before the 90 day warrenty expired. Suddenly Jasmine found themselves with many an angry customer, wanting a warrenty repair on their drive. More than they could afford to handle. So they tried to push the problem off on Rodime (after all, it was their drive that died), but Rodime denied responsibility, saying Jasmine bought the drives, and it was their problem to test them, and make sure they were good. So Jasmine naturally folded under the massive costs of warrenty repair, leaving everyone (myself included) with a dead drive, and no way to get it fixed. Two good things came of this... 1: Rodime folded not long after because of similar problems (from what I understand at least, I know they closed, and I know they had a massive run of drives they sold to the public go out while under warrenty). So they pretty much got their just dues. 2: A few of the Jasmine techs got together and formed a company, that was one of the first in a soon to grow industry of Data Recovery services of hard drives. They formed the company "Drive Savers" which advertises to this day in the back of most Mac magazines. So after that, I decided that it wasn't worth spending extra money on the best reviewed drive, because even the best reviewed could die and cost you big bucks. I paid $400 on an 80 MB external drive, and was able to use it for about 45 days before it died the first time. I was able to get it going again, and in the end, I got about 8 or 9 months of use of it, before I got sick of it crashing and taking all my data with it. I then replaced the inner drive with a 100 MB Quantum that I paid another $400 for, and used that for a few years, until I replaced it with a 1 gig Quantum (for another $400). Today the lower half of my Jasmine drive case, with its power supply and SCSI connectors, powers my SCSI CD burner that sits loose on top after the power brick for its case died. (and the final 1 g Quantum drive is dead too, stopped spinning up, from the sounds of it, I think it suffered from "sticktion" after having run non stop for a few years, and then being shut off and stored for a few more, the 100 MB Quantum I still have somewhere, and the 80 MB Rodime/Jasmine that was the original, made a very nice wind chime). -chris <http://www.mythtech.net>

Need help finding old IBM PC game

by vcf＠siconic.com

I am trying to help someone find a game that apparently shipped with the IBM PC. Below is the description. -- First of all thank you very much for offering to help. This game is a crossing between mastermind and trivial pursuit.The graphics were extremely simple, similar to the mastermind board. The purpose of the game was to guess or identify a famous person or event?with the fewest hints or clues given. The lesser hints needed the more points scored, and I think there were up to 5 (I'm not so sure about the actual number) clues given, if unable to recognize the identity, well, your score wasn?t very high and you were given the right answer and passed on to the next clue. e.g. 1. shot from behind during the performance of Our American Cousin and then hints no.2, 3, 4 & 5?would be even more obvious, gradually disclosing more information in the?following clues.? So this game is different, because in similar games you know the character or the event and you just have to choose a correct answer among four or five options, so there is not much of a challenge, you end up guessing, not identifying which makes it much more interesting. It was a preloaded software game included in the brand new IBM pcs here in Mexico during the mid 90's. It was called "Pistas" , Spanish word for?"clues" or "hints". ??I tried contacting IBM, both here in Mexico and USA, but unless I give them exact model (and almost serial number) of the machine I saw it in, they cannot help me. Unfortunately, I didn't pay much attention to the pc itself since I came across this game a lot in demo pcs all over town. I never imagined they would suddenly stop using it , and when I called them, it simply got me nowhere. -- Any idea what game this person is talking about? And if so, anyone know where to get a copy?

Video toaster and add-on cards

by dan＠ekoan.com

Hello, I just picked up an Amiga Video Toaster (just the CPU unit). Inside on the left are the video toaster cards, but the two right-most slots have full length cards made by Digital Processing Systems Inc. The cards are daisy chained to a connector on the motherboard. Each card has four BNC connectors, a 5-pin DIN, an RJ-11 jack and a three-position switch on the rear slot panel. The back side of each card is covered with a full-length aluminum shield. The only identifying numbers I've found, besides the FCC ID, is "743-770", then "PT2 REV-3, Made in Canada". There is also a Supra memory card with 6 MB (three of four rows populated) and an A2091 hard card. I haven't tried to boot this yet since I need to locate an Amiga keyboard, but I'd be interested to know if anyone has any documentation on the Digital Processing Systems cards. Thanks! Cheers, Dan

Reseating chips

I've now got this problem with my Kurzweil MIDIBOARD (a 6502-based MIDI keyboard controller). A few months ago I had to open it and reseat all the chips. Now I have to do it again. Does anyone know any tricks to keep this problem from occuring? I fear I'm going to have to do this a lot now, especially with the vibrations of playing the keys. Thanks for any tips. - Bob

chip pinout help

by frustum＠pacbell.net

I'm reverse engineering the PC boards in my Wang 2200. I have been able to find most of the chips that have been used on the board I'm currently workign on, except for a couple. Does anybody know the pinout for these? 1) 8T10, quad latch (with either tristate or open-collector outputs, I don't know which) It is a TTL device, made by Signetics, I think. 16 pins. 1976 date code. (N8T10B is the fullly qualified part name) 2) This one is a reverse job. The microcode board has quite a few mask ROM chips. I don't care what the actual part number is, but I'm hoping someone will say, "hey, that pinout is just like a ..." so that I can find a prom programmer to read the thing. If I have to, I guess I could build a parallel port dongle to read them. Here's what I know: 24 pins data out on pins 16-23 pin 1 is +5V pins 2-8, 10, 11, 13, 15 are the address pins pin 14 is either a chip select or output enable; active low pins 12 and 24 are pulled up to +5; chip selects maybe? pin 9 might be -15V (!) Embarrassingly, I can't find a connection to GND. unfortunately, I don't know the backplane connections either, so I can't identify if pin 9 is really -V or just an alternate ground (but I see a bypass cap between the digital ground and this net, so it makes me think). BTW, I have started a web page to archive this information if anybody cares: http://www.thebattles.net/wang/wangtech.html So far I only have one simple I/O board done. Once I have enough of the system figured out, I'll write an emulator for it. That's where all this reverse engineering drudgery becomes fun. Thanks for any suggestions. ----- Jim Battle == frustum(a)pacbell.net

Pin-outs for VT220

by Antonio.Carlini＠riverstonenet.com

>Did you ever get the Pin Out Diagram for the VT220 Serial Connection Port? > >I am currently in the same boat that you were, and can find little or no >references anywhere? You can look on the DFWCUG website http://208.190.133.201/decimages/moremanuals.htm and pick up a number of VT220 docs (the VT220 printset is on its way too ...). You can probably find more at http://www.vt100.net too. However, the EIA connector is just exactly what you would expect ( 2-TX, 3-RX, 4-RTS, 5-CTS, 6-DSR, 7-GND, 20-DTR) isn't it? Antonio

I had thought that maybe this was a possibility, and that input diodes would clamp the output voltage to the digital ground, but I thought that would be too hokey to be workable, and perhaps damaging to either the ROM output or the clamp diodes on the input of the 75157 that the ROM is feeding. Hmm, but then how is translation done on the inputs to the ROM? It is a TTL device feeding the address, so the 0-5v swing (0.5v to 4+v) swing would appear to be an input swing of +15 to +20. I guess I'll have to tack down some wires so that I can look at the voltages in an operating system... > > One more thing, the manufacturer's logo and part prefix are "EA". > >"Electronic Arrays".

Microsoft vs Lindows

by martinm＠allwest.net

This may be a bit off topic. I received a forwarded message that originated from lindows.com. They are in a suit with Microsoft regarding the use of "Lindows,com". Microsoft is suing Lindows for trademark violation. In the message, Michael Robertson, with Lindows, is looking for old documentation of the use of the word "windows" and "windowing" prior to 1983. I can't think of a better resource than this list to find these references. The relevant part of the forwarded message is quoted below. Maybe some of the list members can provide the needed info to lindows.com Martin Marshall ________________quote from forwarded message______________________________________________ Microsoft Corp. v. Lindows.com Update Some of you have sent me email asking for an update on the battle with Microsoft and wanting to know how you can help. In case you missed it, Microsoft sued to shut down Lindows.com earlier in the year. It was a transparent attempt to stifle the inevitable competition which Linux represents. Their allegation was (and is) that they own the trademark for the word "windows," maintaining that no other company should be allowed to use the word "windows" -- not even the "indows" portion. Of course, there are hundreds of products and companies that use the word "windows" - and Microsoft has never filed suit against any of them. That's a huge clue that this suit has little to do with trademark confusion. (If you missed any part of the proceedings to date, visit http://www.lindows.com/opposition to read the court papers and summaries.) Many people have congratulated us, prematurely, on our victory. While the judicial system did block their request to shut us down, a trial is looming for April 2003. At that time, the Judge (or jury) will decide whether Microsoft has a valid trademark for the word "windows" and whether the Lindows.com name is confusing. In the interim, we're moving through the legal process where Microsoft is demanding, as part of the discovery process, everything >from our business plan to our list of partner companies. As you can imagine, it's challenging for a 39-person company to compete with a Goliath that has hundreds of people--just in the legal department alone. This is where we could use a bit of help from our community of Insiders and those on our mailing list. While Microsoft can outspend us with high-priced lawyers and experts, they cannot buy history. We know, of course, that the word "windows" had been used in the industry for years before Microsoft adopted it in the early 1980s for the name of its windowing interface product, Microsoft Windows 1.0. We could, however, use your help in gathering as much evidence as possible to show the usage of the words "windows", "window" and "windowing" before and after 1983, the date Microsoft first filed its trademark application. If you have magazine or newspaper articles, academic papers, journal articles, product manuals, advertisements, textbooks, dictionaries, or anything else that uses the terms, we'd like to hear from you. We'd also like to hear from anyone who had personal experience in the industry during those early years and can recall the history of the early windowing products such as Xerox's Star, VisiCorp's VisiOn, Apple's Lisa, Digital Research's GEM, Quarterdeck's DesQ, IBM's TopView, and others. Please email all your findings to legal(a)lindows.com. As always, thanks for all your help.

Cromemco 64KZ Info Needed

by ipscone＠msdsite.com

Hope this is not a duplicate. The first one did not show up. I have just obtained a Cromemco 64KZ board. This has 64K of RAM and I'd like to test this out this weekend. Unfortunately, I don't have any documentation. There are 4 banks of RAM (16K x 8) Each bank is labeled "page0", "page1", "page2" and "page3". There are also 3 8-pin dip switches: I have a couple of photos at: http://www.msdsite.com/vcomp/cromemco/photos.html Since this is a 64K board and since there is other memory in my system. I'm hoping this allows some sort of bank switching. But without docs, I don't know how to use it. I assume the Bank A/B allow setting which bank a particular 16K might reside but am not sure. And the address lines of A15, A14 are a mystery. Is there a way to switch banks by writing to an I/O port? Location? Can any of you help with an explanation how this works and how I might use the switches? Thanks in advance, Mike

RL02 woes

by pat＠purdueriots.com

I'm having some problems getting my RL02 drive to play nice with my RLV12 in my VAXstation 3200. I've got the drive connected to the controller with a piece of 40pin ribbon cable from an IDE drive, since I have no 'offical' cable to connect the two (or a cab kit for the controller). The drive is set to ID 3, because I don't have a '0' Ready light cover. Also, I don't have a terminator to use. Right now, the drive has its 'FAULT' light on, including when the VAX is powered up and at its monitor. A 'SHOW QBUS' shows the adaptor at address 774400 (I think), and a 'SHOW RLV12' shows no devices attached to the controller. Previously, when I connected a clock signal to the drive's clock in, which was anywhere near 4.2MHz, the fault light would go off. Now, I can't get the light to go off at all, and I'm suspecting the controller. This cable is the second one I've tried, and both cables have had all 40pins going straight through. I also have tried reversing the cable to ensure I had pin 1 the same on both ends, to no avail (could that have nuked the interface on either the controller or drive?). Any suggestions or help would be appreciated. -- Pat

Troubles copying RT-11 tapes on VT103 (continued)

>i) COPY/SYS DDO: DD1: This needs to be followed by the COPY/BOOT DD1:RT11FB.SYS DD1: and then it should be bootable.

The OUTPUT error while doing the COPY/BOOT indicates that block 0 or 2-5 are bad on the output tape. These are the blocks which would receive the boot code. The INPUT error from DD0 indicates that they have a bad bootable tape... if it is the only copy they have, then they really have a problem.

Troubles copying RT-11 tapes on VT103 (continued)

by celigne＠celigne.freeserve.co.uk

I passed along Megan's suggested COPY command to the company who are trying to copy their one and only tape on a VT103. I have just received the following response. Any further suggestions would be appreciated. Out of curiousity, I asked what the machine was and whether they had any pictures. They have kindly passed along a scan of the original brochure, which I'll put online shortly. The VT103 is controlling a CNC milling machine for cams. It was made by a Swiss company called Macor SA, back in 1983. I'm not surprised they're worried about the longevity of the tape! --quote-- As for the copying of the tape no success as of yet, I tried the following: i) COPY/SYS DDO: DD1: I tried this twice the first time the following messages appeared :- FILES COPIED: ?MON-F-SWAP ERROR I then tried to boot the system using using the new copy and it said: ?BOOT-F-NO BOOT ON VOLUME The second time I tried the message was: PIP-F-DIRECTORY INPUT ERROR DD0: ii) COPY/BOOT RT11FB.SYS DD1: This caused the following: ?DUP-F-OUTPUT ERROR DD1: I don't know if this will mean anything to you but the following messages are what is shown on the screen when the system is booting up, I thought it might shed some light on the situation: RT-11FB V04.00 .SET TT: SCOPE .SET TT: WIDTH=120 .SET USR NOSWAP .RUN ID The last command loads up the program that's all I know, because on the tape there are two programs ID and IDT when we want to swap between them we press CTRL C then the message ?MON-F-SWAP ERROR appears and then we enter RUN ID or RUN IDT One thought I did have, do I need to format or erase the blank tape before copying on to it? --end quote-- - Paul

I typed a little about them when I auctioned off all of mine: http://nazas.autonoma.edu.co/hp310.html http://nazas.autonoma.edu.co/hp310orange.html You need an HP-HIL keyboard and a monitor such as this for it: http://nazas.autonoma.edu.co/hp35731a.jpg In addition, you need an HPIB HD with the HPBASIC OS. These machines are OK for instrument control, although I find that my viper card (essentially the same system in an ISA card, which you can then use from DOS) is far more useful. The 9000/220 is the little sister of this one (9000/236C): http://nazas.autonoma.edu.co/hp9836c.html The monitors for these are very hard to come by, so a 220 without a monitor is hardly useful. The one above, with monitor, went for about $200 on ebay back in 2000. How much memory does it have? I think that 220 memory could work in early hp300 models (236 memory certainly worked). The 200 series machines are interesting if you have the software. >Also, are these worth anything?

PowerUser external SCSI HD

PowerUser was the house brand name used by PC/Mac Warehouse. I know they made a line of assorted equipment for the Mac, so I assume they also made stuff for the PC. Most everything was just repackaged items made by others. Based on the name, I would figure it to be a standard external SCSI hard drive. A fairly standard item for the Mac, and quite commonly found in the early Mac days. I might even have a PowerUser SCSI drive kicking around some where (not sure, I had a number of brands, I wasn't very brand loyal, so when I needed a drive, I bought the cheapest... after I got burned on the Jasmine/Rodime fiasco, I stopped worrying about who had the best rated, and just bought on price and price alone) -chris <http://www.mythtech.net>

Which is why people use MP3s, which are compressed, instead of of uncompressed WAV (which is almost exactly the same as AIFF) :-) If you make an ordinary audio CD (ie to use in a CD player not an MP3 payer) you end up with roughly 10MB/min, or a little over 600MB/hour. -- Pete Peter Turnbull Network Manager University of York

Great finds at Auction Today and at Thrift

by jrkeys＠concentric.net

It was a great day at the auction, I was able to get these items: 1. 3-Nextstation Color's was is missing the harddrive need to get a sound box from the warehouse to test them. 2. 1-Nextstation Turbo powers up but no OS on it. 3. One mono display and one 17' color display, cable for both was in the lot. 4. One Next laser printer. 5. IBM 7208-001 8mm 2.3GB external tape unit ($2.50). 6. Several IBM terminals will have get the numbers next time I'm down to the warehouse. 7. Several computers from different mfg. have not tested any yet. Best find of the day was at a thrift (I only had time to stop at 2 of them) it was a Atari 2-player table console titled Missile Command. It has a coin slot for 50 cent to play the game. You sit at this unit and put your hands into the controller pocket that has a big yellow trackball and three fire buttons for each player. They did not have the key to get into the unit and I have not plugged it in yet to test. It's in great shape and is model number 23601. I checked on google and could not find any information on the unit. Anyone know where I can get spec's on this unit and what it cost new?

RT-11 Memory Issues

I can't believe that ADVENTure would eat >up more than 1 megabyte of ram. Is there some tuning bit that I am >missing here? Unless the program has been designed to use extended memory overlays, or specifically designed to use extended memory directives, it is limited to the standard virtual memory address space of 56kb, minus whatever is used by the monitor (and this is carved out of the low 56kb of the machine... the rest of the 1mb is unused). As I already mentioned in another post, you could try using VBGEXE to run it in its own 56kb space.

I found a couple of MP3 files for my Exidy Sorcerer on the web, and they loaded fine at 1200 baud. I suppose the success rate depends on the quality of design of the cassette interface, and the bit rate in the MP3. mpg123 tells me that Galaxians.mp3 is MPEG 2.0 layer III, 16 kbit/s, 22050 Hz mono, it's 520kB long, and "plays" for 1 min 25 secs, including the header. I've heard of other people using MP3 files for BBC micros at 1200 baud too. -- Pete Peter Turnbull Network Manager University of York

Fluke Stuff

by NAVIGATE87＠aol.com

Joe, I use some of them, I had a all or nothing deal so I got them all. The tapes are 18.00 each min order 10. The pod I am looking for is a Z8000 my error. I have a 9100 mainframe also, but It seems to be so software dependent that I haven't figured how to load and save my programs. I need to figure how to hook the 9010 and/or the 9100 to a pc so I can key in my very long programs and save them, or at least load from a PC. I used to use the 9010 but the company policy was not to allow techs to do anything beyond insert tape and run the test. Now I work for a new company and I have to figure how to do all this other stuff oh fun of wearing many hats. Thanks, Don

Semi-OT: Has any interfaced a 360K floppy to a pentium-class PC?

by dlormand＠aztec.asu.edu

Sorry I can't help with the original intent of this thread. I've got enough 360Ks and 1.2Ms kicking around that if I find one that doesn't cooperate, I pitch it and grab another. If the Toshiba won't work, and the BIOS supports the format, get another drive. They're easy to find, and inexpensive. >Windoze XP. But my BIOS doesn't recognize it either, >and it has settings for 360K. >I'm using the floppy controller on an old WD RLL >HD controller. I don't recall if I ever had a 360K floppy on the mb's >floppy controller or not. I got "refreshed" at work, and the new peecee (Compaq Evo) won't recognize my 360K. I NEED that 360K to transfer stuff to my TI-99/4A here. The BIOS doesn't appear to handle anything other than 1.44MB drives (A and B; why would you ever want two 1.44MB?). Is this just a stupid Compaq thing, or is it becoming common among BIOS and motherboard producers to drop support for older formats? I didn't think about using a peripheral card with a floppy controller; I've got a few kicking around in my "lab" at home. With my luck, this Evo won't have ISA slots, though. I'll bet there aren't any PCI cards with floppy controllers... But even if you put a controller that can handle 5.25" drives, doesn't the BIOS still need to be set to 360K? If it isn't there, it isn't there, seems to me. Pardon my peecee-ignorance, it is NOT my favorite platform.

Dec TU-56 Question

by cmcnabb＠4mcnabb.net

I've finally gotten the drive 0 reverse motor on my TU-56 tape drive working. It required the replacement of two transistors on the Motor Drive Control Board. The problem I now have is that the motor only runs at high (18V) speed, even when it should be running at low (9V) speed. Any hints as to where to look next? As an aside, I think fixing the things is more fun than running them.

Semi-OT: Has any interfaced a 360K floppy to a pentium-class PC?

by archer＠topnow.com

Can't make my Toshiba 360K floppy drive work on my Athlon or P4 machine to save my life. I've tried every jumper setting I can think of on the drive. The best I get is a disk failure, where I try to access the drive, and the LED comes on and spins the disk for a while, then fails. Yes, I'm using the right cable. :) It has a 34 pin header plug (remember those?) that used to be standard on floppy cables all those years ago. Jameco still sells them. :) Yes, I set the BIOS to 360K. Still no dice. Anybody have any clues as to what might be going wrong? Thanks, even if nobody has any ideas. :) -- Ross

Latest Delivery - DEC & Intel

by Mzthompson＠aol.com

I've said it before, but it is worth repeating. It is nice once you get 'em trained to bring the stuff to you. The problem is that you have to take it all, it just does not seem proper to pick and choose from their vehicle when they deliver it. Anyway, the latest: 5 DEC BA42 Storage Expansion boxes containing 8 RZ5x drives (RZ55 thru RZ58) also found an IBM drive mounted to a TZ30 mounting bracket in one of the boxes, hey SCSI is SCSI. 5 DEC binders, 3 are Ultrix Sys Admin volumes, 1 for the 5000/200, 1 for the DECstation 3100 AutoCad for the DECstation 3100 Ultrix 4.4 tapes (VAX) Kodak laser printer VME chassis and a couple prototype cards. 6 Gateway 486 desktops 9 Compudyne desktops, a couple are 386, the rest 486 I could have done without the Compudynes. Many do have network cards worth pulling. Also at least one has some 4mb 30 pin SIMMs. Mike

Mac benchmarking

by spectre＠stockholm.ptloma.edu

While trying to benchmark Fusion PC (as a IIci) on my AMD DOS PC, I threw together a small implementation of the Sieve of Eratosthenes and Ahl's Simple Benchmark to test integer and FPU performance. Like everything else in my life, this snowballed, so here is the fruit of my labours for people who are interested in benchmarking their 68K Macintosh. http://www.floodgap.com/retrotech/mac/ahl/ The reference is a Mac Plus running 6.0.8 with 2.5MB RAM and the stock 8MHz 68000 CPU. However, to make it really vintage, I tested it against a Mac Plus running System 1.1 and it worked! 512K RAM recommended. Just to prove I have a sense of humour, the benchmark is in Modula-2. Some of the tests ran on my classic Mac stable had rather startling results. For example, the Daystar PowerCentral control panel seems to accelerate FPU performance on the IIci, even with no Daystar hardware installed.

PDP 11/24 Wierd Unibus Setup

by cmcnabb＠4mcnabb.net

I've pretty much got this PDP-11/24 up and running, except for one confusing detail. There are some (what I consider to be) strange cards plugged into one section of the unibus. In this box, there are three seperate sections of bus. The one on the right has 9 slots, and contains the cpu, memory, dl-11, etc. The one on the left has 4 slots and contains the bus terminator, as well as the controller for the RA-80. It is joined to the right hand bus by an extension cable. The middle section of bus is the wierd one. It contains some kind of power supply cable and a bunch of single-height flip-chips. Here is the setup: 1 2 3 4 A Power B M205 M660 C M116 D M113 E M112 F Anyone have any ideas what this is for? Thanks.

Documentation for DEC T-11 evaluation board?

>I'd like to find the schematics for the DCT11-EM board (or even >better, a board based on the J-11). I have a scan of EK-SBC02-UG-001 and it has schematics (and ROM and FPLA listings) for that system. IIRC it is T-11 based. That should eventually appear at the DFWCUG site. If you want it right now, I'm reasonably sure that it is a later version of http://www.spies.com/~aek/pdf/dec/pdp11/EK-KXT11-UG-PR1.pdf which you can get right now. I doubt that either of these are *exactly* what you asked for, but they may serve as a useful starting point. Antonio

Does anyone have a manual for this? My clock appears to work except that it's not setting the time automaticly. It recieves WWV and the Data light blinks and the Capture light blinked a couple of times but the correct time never appeared on the display. Also what do the Hi Spec, Trim Up and Trim Dn lights mean? Joe

IBM 3295 Plazma Display

by mross666＠hotmail.com

>>Before I give in to the temptation to e*** this critter, anyone know >>anything interesting about it or care to make me an interesting offer >>(sell/trade/etc.) on it? >> >>BIG IBM Mainframe (I think) display. Display unit only... >I haven't heard of anyone getting these to do anything other >than what they were designed to do. There *are* possibilities, since 'they were designed' to talk to 3174 controllers and *they* are intelligent devices that can do a lot with the right microcode. They talk coax 3270 to a 3174 controller. If you can get a 3174 with token-ring or ethernet connectivity (t/r is common, shows up on ebay from time to time, and is cheap; ethernet is like hens teeth and still worth a fair bit) and the latest microcode from IBM (C6 or better), the 3174 supports tcpip & telnet, allowing you to use the 3270 terminal to connect to any ASCII host across the LAN. I *think* that only applies to common or garden 3270 CUT devices however - and the 3290 series stuff is DFT, requires download (DSL)microcode from the 3174 to work, and can't be used for telnet. I *think*. I have a 3174 set up for telnet; I have a 3290. I'll get 'em together sometime and see if it works.

VAXcluster ?'s

by rschaefe＠gcfn.org

Well, I now have the fixings for an interesting VAXcluster in the basement: VAX 6000 320, VAXstation 4000 90, VAXstation 3100 40 (I think), VAX 4000 200, and some maybe-OT alphas (DEC 3000/300X, DEC 3000/700, and a DEC 3000/800). Also a TU-81+ w/ RA-81, and a RA-91 in the 6K machine. Support hardware includes a DELNI, DECserver 100, and an HP bridge to segment the cluster off the network proper. Now I have to figure out how I'm going to tie it all together. The plan so far is to cluster all the VAXen over the DELNI. I don't have any CI equipment, and in any case IIRC only the 6K would be able to use it. I'm not positive what I'm going to do with the alphas, but I'd like at least one of 'em in the cluster too, maybe dual-boot them into OpenVMS or NetBSD. I think OpenVMS 7.? still supports the old VAXen, and from what I've heard on c.o.v it's recommended over the 5.5-? currently installed on three of the machines. Ok, I confess this was partly to brag, but has anyone done something neat with a VAXcluster that I could do too? I'm not to the point where I can spark everything at once (need a new power circuit for the 6K for one thing-- did the 220V conversion already, thanks), but I'd like to have a direction early on, kind of a goal to work towards. Anyone want to share? Bob

Copying tapes on a VT103?

by mbg＠TheWorld.com

>The VT103 unit has two tape drives and I think you can copy from one to >the other it just a matter of knowing the correct commands, hence the >reason for this email. Therefore I would be most grateful for any >suggestions you could suggest for the commands required to copy from >drive 0 to drive 1, we have so far tried the following: > >Note :- RT11FB.SYS = Boot program (I think) >i) COPY/BOOT RT11FB.SYS > TO: DD1 >ii) COPY/SYS > FROM? DD0 > TO? DD1 > >The second method kicks up the following: - PIP-F-FILE NOT FOUND If these are the commands as used verbatim, then it is looking for a *file* by the name of DD0. You need to specify the device name, so use 'DD0:'. (I'm surprised it didn't report the name of the file it didn't find.) So, the command should be: COPY/SYS DD0: DD1: Doing this, however, will not result in an optimized tape... it may actually take a relatively long time to boot. I actually got a TU58-based system to boot in as little as 30 seconds by judicious placement of the system files. If you (or other people) are interested, I could write it up...

Need help finding information on the following transputer boards

by rmeenaks＠att.net

Hi, I am in the process of compiling a list of inmos transputer boards (excluding trams). I have information on most if not all of them so far except the following: IMSB013 - Did it ever exist and if so, what was it IMSB019 - ditto anything after IMSB020??? again, I am only looking for information on the IMSB series and not IMSB4?? trams... Thanks, Ram PS: Finally figured out what was causing the HTML messages. First of all, I apologize for that. Our confidential signature that gets added by Microshaft Exchange only supports HTML so even if you send your emails via text, the server sends them out in HTML. Our useless SAs, claim that it can not output plain text. Is this true???

Microsoft vs Lindows

by rigdonj＠cfl.rr.com

At 10:47 PM 8/17/02 -0500, you asked: > >Why has Micro$oft not gone after "X Windows", this looks >even closer to the actual name of Windows, but since it >is freely available they cant zero in on anybody/company. For one thing they'd have to go after companies like AT&T and HP. MicroSlouth couldn't push them around the way that it does small companies. Joe

New finds for Musuem

by jrkeys＠concentric.net

Well over the last couple weeks the Mac XL from eBay arrived in the mail but was DOA. It will go into the repair pile at the warehouse. Got a nice book by Dr. Jerry M. Rosenberg called The Computer Prophets from 1969. Here's a short list of some items I picked up. 1. Nice Next KB for the N4000A monitor at the local Goodwill (still looking for the computer). 2. Galactic Pinball cartridge for the Virtual Boy console. 3. I-O Corp. model 2677C terminals (3 of them) at a auction for 50 cent each. 4. IBM 3180-02 terminal for 50 cent at same auction. 5. Prc Realty System model 101 Data terminal based on the TI 745 portable. 6. IBM 8503-001 mono monitor. 7. Large box with a Mac Plus and all kinds of goodies for it for free at the auction. 8. hp 700/70 terminal for $3 powers up great but need the kb for it. 9. A Jetbook 386sx notebook for $10, needs battery charger. 10. Robot named 2-XL from 1978, needs a little care. 11. TurboGrafx 16 with 8 games on the HuCard for $20 at the flea market. 12. AS/400 Barcode labeling software. 13. About 20 more mousepads for the collection. That's it for now there were lots more items but some are too new to list. Keep on computing.

Old Sun Equipment Available

by bill＠cs.scranton.edu

I have some old Sun Sparc systems that need to find a new home (preferably not the dumpster in the parking lot). Is there any one here who might be interested. I have SparcStation 1's I have SparcServer 330's and even a Sun4/something that was in a 7' high rack and includes a 9 track tape drive (which worked quite well the last time I used it.) All of this stuff is at the University of Scranton and would need to be picked up. It's free, although I wouldn't turn down some PDP or VAX trinkets (expcept async boards :-) in exchange. Please reply directly to me as I am currently not reading the list. bill -- Bill Gunshannon | de-moc-ra-cy (di mok' ra see) n.
