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*. If you like to use flashlights to peer into machines and such, and like the idea of having a tiny but astoundingly bright one to carry with you everywhere along with your wallet or house keys, this is the way to go.

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).

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.

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.
