They're used in some applications where radioactivity is a concern. I remember seeing an invoice for one (went in some medical equipment) that priced them at $170. Jim

Looking of Digital Alpha CPU/Motherboard

by workstations＠poczta.onet.pl

Hi all, I acquired a small lot of Alpha 166 and 233MHz CPUs. Unfortunately, the AXPpci 33 motherboard I have does not work with the Alpha 21164-AA CPU I found in the box of Alpha CPUs sent to me. Does anyone know which DEC motherboards work with the Digital Alpha 233MHz 21164-AA CPU? I tried looking for information on the net, but found very few pointers.

It might just be a PAL/NTSC thing. No, we know about PAL, we just choose not to use it.... ;-) -dq

Just curious about injection molding or casting

Within another ten years, surplus stereolithography machines (and other "Santa Claus" machines) will be available to us. Good ones go for $250k, but a friend of mine and I thought we could engineer one to sell for about $25k, and others are likely having the same idea... For those you you who aren't familiar with these, think of them as "3d plotters". Some carve away at a block of material until the object of desire remains; others deposit tiny beads of metal that are sintered (?) together; my favorite uses a polymer fluid and a UV laser; the laser draws a cross-section on the fluid, which hardens the polymer; a tray under the first cross-section lowers slightly, the laser draws the next cross-section, and so on, until you have The Object. I think another spews plastic beads in a fashion similar to the sintered metal. Anyone have any hands-on experience with them? I could watch, but they wouldn't let me touch... ;-) -dq

Wanted: TeleVideo CP/M machine(s)

by dhquebbeman＠theestopinalgroup.com

I used to use these at a former orkplace... a cow-orker ended up with a few, and is down to the last one, which he's kindly holding for me... -dq -----Original Message----- From: StormErage(a)aol.com [mailto:StormErage@aol.com] Sent: Thursday, August 30, 2001 3:06 AM To: classiccmp(a)classiccmp.org Subject: Re: Wanted: TeleVideo CP/M machine(s) I own a Televideo 803 system (not a portable). I have the complete system with manuals, power cords, software, etc - even one OLD game called "mortar". I bought the system when it was new back in the early 1980's. Still runs like it always did - I have it in an air conditioned storage unit.

Sorry

> If you have any VAX 11/7xx documentation, I'm interested in buying it. > Let me know what you have and how much you want for it... Over at http://208.190.133.201/decimages/moremanuals.htm you will eventually find about six or so of the VAX-11/780 related technical manuals. (They have them already, you just need to wait until they get around to putting them online). Antonio

PC/AT memory boards

by zaft＠azstarnet.com

I've got an old genuine IBM AT (8 MHz) that has a couple of 16bit mystery boards in it... 1) Marked 55x3543, google says 0.5 to 3 MB board. It has a 16450 on it, a total of 12 30 pin simms, a male DB9 (okay, I guess it's a DE9) and a female DB25. I assumed it was a serial port and parallel port but it doesn't show up as such in the machine. Also since these appear to be 256K simms I expected the machine to boot with 2MB of RAM or more but it only came up as 1 MB. I'm suspecting it's configured wrong or there's a conflict but of course I don't have any docs... anyone? 2) Another memory board, 18 256Kbit chips, marked EV159 and has a big EVEREX chip on it. Google says 3 MB expansion board, same questions. I assume this motherboard has 512K on it, so... this board might be okay but I'd like to know what the switch settings are in case I decide to add memory to it (anyone know a cheap source of 41256s? Any help (docs especially) would be appreciated.... Gordon Zaft zaft(a)azstarnet.com

Sorry

by lgwalker＠mts.net

Sorry about this, list, but I've just moved out to my retirement home and I really need every cent I can gather, so I sold a Borsky S1000 handbook and a PDP8 maintenance manual without offering it to the list. Once I get some of my multitude of boxes unpacked, I will be offering many other duplicates and non-essential things. I'm sure there is much that would not excite much interest on EPay but would be of interest to the list. I'll keep you posted. ciao Lawrence Reply to: lgwalker(a)mts.net
