PS/2 - E

by csmith＠amdocs.com

I have a PS/2 - E. It's a little tiny 80387(?) with a 387 math coprocessor. Four PCMCIA slots, and a floppy drive. Integrated video, parallel and serial. 1.4M floppy, and unknown(right now) hard drive. Does anyone know anything about it? What can I do with it? Will OS/2 work? What interface does the hard drive use, BTW? What are my chances of getting BSD or linux to drive the PCMCIA slots? Anything else I should know about this one?

Harris Model 8 CPU

I second this. I now use them exclusively, while my trusty Maglite sits in a drawer. I use Photon lights, http://www.photon.com, and I like them a *lot*.

Core Memory Interfacing?

by bill＠timeguy.com

Right off, let me say that I know next to nothing about the realities of using core memory. I only know that it looks like pretty cool stuff to play with. Would I be completely off my tree to try to build a core memory interface from scratch, assuming I had a pre-strung core frame with all the cores and wires intact? When I say "interface", I mean basically something that will let me talk to the core from a PC or from my recently-completed Mark-8 using TTL or CMOS levels. If I have a 64x64 frame, would I just need something on the order of 256 driver transistors (one to drive each of the X and Y wires in either direction) plus some kind of op-amp or comparator circuit to monitor the sense wire (is there just one of these per frame?) and determine whether or not a bit has flipped during a read pulse? Or are there all sorts of ghosts and goblins lurking in core memory that I don't want to confront?

Harris Model 8 CPU

by geoff＠pkworks.com

I got a phone call early this morning from one Harry Landis, a surplus dealer in Foxboro, MA, who knows I like old computers. He has eight boards from a Harris Model 8 CPU, said to be used in their 60, 600 and 700 systems, including the two board CPU. He wanted to know if I wanted them. I said no, but that I'd check around - hence this e-mail. I've not seen the boards and do not know their condition, nor do I know what Harry wants for them (and, no, I'm not financially involved in this in any way), but if anyone's interested give Harry a call at 508-285-7568.

I have one of those squeeze model LED ones clipped to my keys. Works nicely for temp lighting (the squeeze and hold activation makes it a bit hard to use for long term lighting). It was marketed as a "white LED", but it definitely casts a blue tint in my opinion. Not enough to off set colors to an indistinguishable point, but enough to tell that it looks blue. I use the thing all the time when glancing for wires in a dropped ceiling, or when looking into the dark corners in or behind a computer case (just to bring it on topic). Overall, not bad for a $3 item (actually, I got it free as a gift, but have seen it sold for $3) -chris <http://www.mythtech.net>

Enhanced DRI PL/I-86 Compiler Available

A couple of years ago, I put some finishing touches on a project I began back in 1988, when I got a copy of the DRI PL/I-86 compiler. Back then, it wasn't the freeware that it is today. But of course, today, you can download it from either of the two sites above. My goal was to modify it so that it one could use the Microsoft linker and librarian instead of the DRI linker and librarian; with this change it would be possible to mix object modules from other Microsoft-compatible compilers. Also, I wanted to revise and extend the runtime system. I completed most everything except providing access to DOS environment variables. But the DATE() and TIME() BIFs work as they should, and you can pass the command line arguments by defining them as arguments to main() much as in C. DRI and Microsoft both used the Intel OMF format for the object files, so it wasn't hard. But like many projects, it just got stalled for along time. I recently packaged it up and forwarded it to Peter Flass, noted PL/I advocate who's omnipresent on comp.lang.pli. He's going to include it in some archive, but didn't mention which. You may or may not end up seeing at the two above sites. But if anyone out there is interested in it, you can also obtain it directly from me.

As Sellam implies, it's only the boot PROM (P5) you need to change, not the state machine PROM (P6). I have a card somewhere with BOTH sets, switch selectable, but I haven't seen it for a while.

To punish someone for distributing equipment which could be used to commit a crime is just as ludicrous. It does not matter whether the alleged crime involves a computer or not. You don't punish people for selling rat poison, kitchen utensils, notebook paper, or photocopiers, do you? What about panty-hose and ski-masks -- I hear those are used in crime a lot! :) When will we have the digital millennium hosiery act? It would be absolutely idiotic to punish someone for distributing software which _might_ be used to illegally copy things to some other media.

Strange idea in VAX

by Antonio.Carlini＠riverstonenet.com

>But does OpenVMS/vax support USB? No but since you're doing a PCI driver, a USB driver should be a breeze. Having a Qbus framebuffer and a USB keyboard and mouse would be fun :-) Now that I look I don't see any PCI widgets for the VAX 7000/10000 or the DEC 7000/10000. So I think PCI and TRUBOchannel are pipe-dreams. Pity, they would have been the easiest ways to get a framebuffer. Now if you get a TurboLaser (AlphaServer 8200/8400) they *do* have PCI expansion available, so you could do PCI graphics there. Possibly even multiple graphics heads :-) Antonio

I'm geting old. Here's an early reference, from the comments of the source code to FIG-FORTH 1.1 dated 17-September-1979, one year after I met him on exit from Harrisville: ; APPLE FORTH BY CapN' SOFTWARE $40.00 ; EASYWRITER (word processor for APPLE ; by CapN' SOFTWARE) $100.00 So it appears it was an Apple II package before it was an IBM package. -dq -Douglas Hurst Quebbeman (DougQ at ixnayamspayIgLou.com) [Call me "Doug"] Surgically excise the pig-latin from my e-mail address in order to reply "The large print giveth, and the small print taketh away." -Tom Waits

From dim memory, it was running V1.5. Huw Davies | e-mail: Huw.Davies(a)kerberos.davies.net.au | "If God had wanted soccer played in the | air, the sky would be painted green"

Shoddy Hardware (Was: Re: WW fixtures (was Re: "New" PDP-8))

by ajp166＠bellatlantic.net

As someone that runs a P166 on an ASUS board in a higher end case that can hold and run 3 RX56s{5.25" full height} and not melt, I would say better gives better. FYI: it's a 24/7 box that I rely on to work and it does quite well with NT4. Good PCs can be built but, you do have to work at it. Allison

IBM 3192s

by pat＠cart-server.purdueriots.com

I've got a pair of them sitting here, looking for a home. They seem to power up, but don't display anything. Just looking for enough to buy me a lunch + shipping. Also have for dispersal: StorageTek 2920 9-track PERTEC interface tape drive, might need a new head, otherwise completely functional. $5 + shipping -- It's 150lbs and rackmount - about 24"Hx18"Wx12"D If no one wants it, it'll end up as scrap. UPS/FedEx/USPS won't ship this I'm sure. Mac Quadra 610, Mac IIci, Quadra 700. $10ea OBO. Apple //e. One has Disk ][ interface + 1 drive + 64k RAM expansion card, one has Duodisk interface and drive. I'm willing to give out as much of these as wanted. $5 each, what I paid for it, + shipping. Thanks for supporting your local poor college student. -- Pat

DEC part aniti-static matt?

by fernande＠internet1.net

Hello Listers, Awhile back I scrapped/recycled/trashed an R400X DSSI expansion chassis. Between the steel back cover a back of the backplane, I found a plastic sheet, part number 7438980-01 rev. c01g?r0? The question marks follow guesses on smeared digits.... My question is this: Could this succesfully be used as an anti-static work surface? It doesn't seem to attract lint like I would expect, which makes me wonder. Maybe it was simply to protect the backplane from shorting? Would I be better off using a sheet of cardboard? It would be nice to have something to lay cards on while sorting/re-assembling/etc. Chad Fernandez Michigan, USA

The Future End of Classic Computing

by mythtech＠mac.com

>(greedy self interest note: anybody know how I can keep a > copy of the MR trailer on my PC for repeated viewing?) Rumor has it (haven't gotten around to trying, as most trailers suck anyway), if it is streamed with QuickTime, and you have the QuickTime 4.0 or earlier player, you can bypass their anti-save ability. Also, I know a number of the non savable streams become saveable in QuickTime 5.0 IF it is registered as a Pro version. Humm... better send Apple's QT team to jail, sounds like they are releasing software that can bypass copy protection. :-) -chris <http://www.mythtech.net>

Many probably own only one hammer, > > People here don't have soldering irons, they don't have tap and die sets. > What the heck do they use to repair computers (;-) in case you're wondering). Once upon a time, when I worked as a programmer for an hourly wage, with time-and-half for overtime, and lived rent-free, I was able to acquire a reasonable set of tools, but most of them were for the other hobby, working on my Audi's. But I do have a logic probe, a RatShack-labeled Ungar iron, heating elements up to 43 watts (glows red!), and lots of TTL parts, etc. No scope, no analyzer, nothing esoteric. But a breadboard, a manual wirewrap tool, a few spools of wirewrap, protoboards, some material for making cheap PCB boards, cheap dykes of various sizes. I used to have heat sinks, IC pullers, two rechargeable Wahl irons (well, I still have one). But now I mostly have a salary that grows 1% behind the rate of inflation and a mortgage that consumes most of the cash, with food coming in second. So, debugging hardware ofen involves totems, incense, etc. Or lots and lots of "remove and replace"... ;)

DSD-440 manual needed

by mranalog＠attbi.com

I really need a copy of the manual for a Data Systems Design DSD-440. If I knew what I was doing I would just ask for the switch and jumper settings, but that's not the case. I would like to get a copy of the entire manual. If someone has the manual scanned already, I can take 2MB email attachments. --Doug ========================================= Doug Coward @ home in Poulsbo, WA Analog Computer Online Museum and History Center http://dcoward.best.vwh.net/analog Analogrechner, calculateur analogique, calcolatore analogico, analoogrekenaar, komputer analogowy, analog bilgisayar, kampiutere ghiyasi, analoge computer. =========================================
