What about an IBM XT with a Big Blue CP/M Card, AND a Trackstar 128 AND a Hydra (MacPlus) board? Wouldn't that give you 4 processors in one machine? One could also run an Amiga with an 8088 Bridge board for dual processors. Or, an Apple IIe, IIgs with a Transwarp card for two processors? Three if it has a Microsoft Softcard... Which makes me think of the Zip Chip and Rocket Chip for the Apple IIe/IIgs series. Did these chips also work in the C64 and other 6502 machines? I remember working with them, but don't have one for either of my IIgs machines... I *DO* have an Orange PC card that will turn a PCI Mac into a PC. But, I don't have the required cable or software for it. So, it's merely a curiosity at this time. That would make a Mac a Dual Processor machine, wouldn't it?

AT&T 730 MGT graphic terminals

They can be regular dumb terminals or "layers" terminals, which is a really rather interesting, pre-XTerminal remote windowing system worked on by, among other luminaries, Rob Pike. As I recall, they came out with an X cartridge for the 730 since layers never caught on. I only saw NCR rebadged X Terminals during my time at AT&T, so I assume the X cartridge didn't catch on either, even internally. > Any AT&T 3B2 owners out there have one of these in a working state? Don't think many of them ever made it out of AT&T...at least I've never seen one in the wild.

Apparently not, at least for some of the Eastern Bloc clones; see http://hampage.hu/tpa/e_index.html. For the Hungarian machines, cards were definitely physically different, I'm betting things like power supplies are local creations and anything using LSI (F-11 clones, for example) were undoubtedly somewhat original due to differences in the manufacturing processes the Soviets had access to (and DEC never made anything that looked like a K1801VM1). Very faithful clones as far as the software was concerned, though.

multiple cpu machines Re: rogues galleries

by ken＠seefried.com

If you can find a Hauppauge 4860, you get an i486 and an i860. Toss in a DAC960E EISA Raid controller and you get an i960. And an NE3200 EISA network card, and get an i80186. Add a National Instruments AT-DSP2200 EISA data acquisition card, and you get an AT&T DSP32C. Add a A Hercules Graphics Station card and get a ti34010. Add an Opus card or two and get more (mc88100? SPARC?). That's 8 processors, 6 of which are directly available for fiddling. I've had, at one time or another, all these cards, but since I never put them together, I guess I don't win.

I assume, if they are taken off without damage to them, they would simple clip back on? I have never taken a keyboard apart yet, and will no doubt need to someday. I probably won't bother until a keyboard, or keys, starts failing. Regards, Andrew B aliensrcooluk at yahoo.co.uk

If anyone would like a full set of HP 9000 manuals please contact this guy off list as they are heading for the skip! He has just posted to the UK a full set of Masscomp manuals so he is very helpful, he is located in the USA in Kingstowne VA. "I just wish I could find as good a home for our set of HP 9000 model 375 manuals. There was a guy in France, but he cannot afford the postage. Now even the janitorial staff won't take them out for me; the pile just sits there with the "Trash--please remove" sign on top. :-(" Please reply off list to: "Newquist, Jonathan D" <NewquistJ at state.gov>

When 4mm Drives Eat Tapes

by rdd＠rddavis.org

While attempting to restore some files from a 4mm tape, using an HP SureStore Tape 2000 drive, something happened to me for the first time: the drive made a strange moaning sound then stopped reading the tape. Not only did the drive stop reading the tape, but it had begun eating the tape as well, nearly chewing all the way through it on one spot. I'm guessing that this is a problem which, if not affecting others yet, will soon start affecting others who are relying upon such drives for backing up and restoring critical data. Fortunately, I'd recently switched to using DLT IV drives for backups, but a few files that I wanted to restore were still on other tapes. Does anyone know where rubber parts for these drives, like rollers, can can be purchased, so that others with these drives can replace them and avoid what I experienced? I should have realized that something was about to go wrong with internal parts as well when one of the drive's rubber feet began to stick to the metal chassis it was resting upon. -- R. D.

differential SCSI conversion

by compoobah＠valleyimplants.com

I've been poking around inside my HP9000/C180 machine (1x SE Fast-10 narrow SCSI, 1x FWD integrated, 1x FWD GSC card). I am aware that this machine is still slightly stretching ontopic, but the diff part is definitely ontopic. Currently, it has 1x4GB and 1x2GB, which leaves little free space with a very off-topic OS (HP-UX 11.11) diff SCSI drives, while technically superior to SE, are difficult to find, so I'm looking at alternates. Looking at the machine, the SCSI busses appear to have a standard SCSI chip feeding into differential drivers. Is it possible to gracefully remove the diff drivers and convert it to single-ended operation?

differential SCSI conversion

by compoobah＠valleyimplants.com

Quoth Zane: >Have you thought about getting converter boards to convert SE drives >to HVD? Yes, they made such things. Are HVD drives really that hard >to get? I've got a DEC DWZZB converter, but that requires messing with the StorageWorks shelf and cables to trip over and set up every time I use the machine. I also have a pile of SE drives, including 1 9GB. Diffs seem to be most common in the 4G and under range, and all bays are full. It also seemed like a reasonable way to make an old machine more useable without spending money, pulling a couple of driver chips and putting in jumpers- but perhaps not. Maybe NFS is a better answer.

When 4mm Drives Eat Tapes

by aek＠bitsavers.org

> I'm guessing that this is a problem which, if not affecting others > yet, will soon start affecting others who are relying upon such drives > for backing up and restoring critical data. Decomposing rubber components has been a problem for digital tape transports for at least a decade or more now. I know of no vendor who supplies replacements for the dozens of different QIC transports, for example. Crisis Computer used to fix HP transports, but they do not sell parts, only expensive refurbed complete units. This should be a business opportunity for someone, but I don't know of anyone who is selling replacement rubber parts for digital transports. Anyone who has historically significant data on tape should get it OFF of that media as quickly as possible and onto something that is more easy to migrate in the future.

Tentative early news of VCF East 4.0 date(s)

by evan＠snarc.net

Hi all, This isn't official yet, but we're aiming for Saturday, May 19 next year. We might add Sunday, May 20 as well, but that won't be decided anytime soon. Location is the same as East 3.0 was this year: the InfoAge Science Center (infoage.org) in Wall Township, N.J. We considered having the East event on the same weekend as VCF Europa, and having inter-VCF things such as IRC terminals and videocasts, but unfortunately it didn't work out because of some other BIG news that I can't announce right now but might within a couple of weeks. :-) - Evan

sanyo lat-200a

by fa475919＠skynet.be

Hmm, there are indeed some smaller components I hadn't noticed that might indeed be memory, Some smaller unbranded 2x HC240's, 4x HC74's and some rather large ones : Malaysia 8835/ HM6264ALFP-12T. I'm still not sure I'm following, whilst you are probably giving me usefull information. My knowledge on the pure details of a harddisk are fairly limited. I know how it mechanically works, but how the data is carried is another thing. What does this mean: "From the OMTI chips you mention, I am now almost certain that's a raw interface, possibly simular to ST412." Could I use the 50 pins connection from the motherboard to the board for any other purpose ? Is any 26 pin HD in 3,5 inch available? What are my options? The original 26pin harddrive is dead, the step-motor to rotate the hard discs is fried. (Btw, the original HD takes its power from the datastrip). Thanx & Greetz Stijn

Use an adhesive to stick the layers together and to the metal roller otherwise they will work themselves up toward one end. Inner tubes are available in a wide range of sizes from bicycles, trade bikes (mountain these days?), motorcycles, cars, lorries and tractors and they can be stretched a lot. Roger.
