Thanks Tony, There are several large chips that say "Xilinx XC2018-70 PC84C A6396A9103E." More revealing, maybe, is what I just spotted amidst stickers and components: "Central Processing Unit." Heh. So this appears to be a big honkin motherboard from some...analytical thing. Another largish chip says "Dallas DS1287 Real Time" followed by more numbers. I am gonna hang this on my wall. Unless someone on the list is dying to have it. --MB --- Tony Duell wrote: > > Hey all, > > > I was at the local computer junkyard today and snagged a logic board I can't > identify.

I've sort-of come across a company called 'Link Systems'. In fact one of my ASR33s (Data Dynamics case/electronics) is badged by them. >From what I remember they made computerised (mostly) analytical instruments, spectrometers, electron microscopes, that sort of thing. The computers were sometimes based on PDP11 CPUs (or occasionally DG Novas IIRC). They may well have designed their own CPU boards later on, but I've never seen anything like that. My guess is that you've found a board, possibly an interface, possibly a complete CPU, from one of these instruments. What (if any) large chips are on it? -tony --- end of quote ---

Somewhat OT: Then & Now.

Then... Big timesharing companies... Now... Application Service Providers Then... Service Bureaus... Now ... Web Hosting companies Is it repackaging or recycling? -Joel -----Original Message----- From: owner-classiccmp(a)classiccmp.org [mailto:owner-classiccmp@classiccmp.org]On Behalf Of David Vohs Sent: Friday, April 21, 2000 22:53 To: classiccmp(a)classiccmp.org Subject: Somewhat OT: Then & Now. This is something that I had posted on the comp.sys.cbm newsgroup that I thought would be intresting to see how much the computer world has (or hasn't) changed starting right around 1980 or so. So if you've seen this before, I apologize. Anyway, here are some things that have changed (or have they?) in the computer world: Back then we had: Daisychained peripherals to the Commodore IEC serial bus. Now we have: Daisychained peripherals to the Universal Serial Bus. Back then we had: The Original Macintosh. Now we have: The iMac. Back then we had: Computers with a built-in RF modulator. Now we have: Video cards with a built-in RF modluator. Back then we had: The Original Macintosh II. Now we have: The G3/G4 PowerMac. Back then we had: The Commodore 1581 head-knocking/Click of Death problem. Now we have: The Iomega Zip drives' Click of Death problem. Back then we had: The Macintosh Portable. Now we have: The iMac. Back then we had: The Tandy Model 100. Now we have: The PalmPilot. This is all that I could think of, I want anybody who can think of anything that hasn't changed to add something on this list. Let's show people that the old phrase "The more things change, the more things stay the same" is true! ____________________________________________________________ David Vohs, Digital Archaeologist & Computer Historian.

Things that make you sick!

by rigdonj＠intellistar.net

Mike and I went to one place today and found the remains of a Data General Aiivion (sp?) in the scrap metal pile. We had gotten there too late to save it. :-( I did get the CPU module out of it. It has three large ICs on it. Two are XC88200RC25B s and the other is a MC88100RC25. Can anyone tell me what exactly these are? Joe

Interesting finds; 1801, National Semiconductor RM-665, Grid,HPs..

>A few years ago in a surplus store I found the RCA CMOS databook that >contained (sketchy) specs for the 1801. However, the idiots were not I have basic specs fot the pair, deeply burried though. >The databook indicated that the 1801 is a two-chip set, which consists of >the CDP1801C and CDP1801R, the former containing the control circuitry and >that latter containing the registers.

Not quite true. the pair were used by special customers for quite a while as they were by basic construction rad hard. There were a few minor instruction differences as well, the 1801 had fewer than the 02. Allison

VAXstation 4000VLC

by healyzh＠aracnet.com

On the topic of VAXstations, does anyone one the list have experience with hacking VLC's and or LCD's? I'm wondering how feasable it would be to hook an LCD display up to a VLC, and if it would be possible with off the shelf hardware. The other alternative I'm thinking of would be to pickup a cheap laptop, load Linux/X-Windows on it, and use it as an intelligent X-Terminal. At this point, you're probably asking, what on Earth am I trying to do. Well, I've decided I want a VAX "Laptop", and while I really doubt I can have it battery powered I want to see what I can do starting with a VLC as the base. I figure as long as I can get the final product about the size of an old Toshiba 5200 I'm on the right track. Of course I'm also thinking that if I can find the time to do this and do it right I'll have to build my own case for all the guts of the pieces. If nothing else a VLC and a Laptop used as a terminal should make a nice small easily portable VAX. I figure I'll initially try this out with my Mac PowerBook 540c since it's got built in ethernet and I can run eXodus on it for DECwindows support. However, as the 540c is only 640x480 I figure it's only good for a couple Mac telnet windows or a DECterm via X. Anyone have any ideas? I hope to start in on this next weekend, but it will depend on how soon the VLC I just bought for this takes to get here. As for the why, well, why not :^) Zane | Zane H.

Another VaxStation 3100 question

by dogas＠leading.net

Another one of my VaxStation 3100's is a KA42 ver 1.3. It has LOGIN and (SET) PSWD commands in the DCL whereas my KA42 ver 1.2's do not. I don't know the password for the 1.3 box. Is there a way to reset it or find out what it is? Thanks again. - Mike

VaxStation 3100 revisited

by dogas＠leading.net

Well... Alot of intervening miles later, one MMJ cable later, one doubly terminated BNC T later, my VaxStation 3100's a little happier. Still not booting though. SHOW DEV shows ESA0 (default boot) and the floppy (I forget the dau) and DKA300 which it will not boot from. I take it these were booted from somewhere else on the network. How can I get VMS on the DKA300 or at least see what's already there? Help! Thanks - Mike

Interesting finds; 1801, National Semiconductor RM-665, Grid,HPs..

by dogas＠leading.net

Hi all, I hope everyone is having a great weekend. Another item scored along with the rest of the subject's "interesting finds" was an Applied Microsystems thingy (an ES0130 (???)) It's a multibus gizmo in a small chasis missing the front plate. On the back , there are two db25 ports for Terminal and Computer, and a BNC for a Trigger. There is sticker on top listing two options installed: 1) AMC/ES-68000/8 and, 2) AN/403158. Another sticker on top says 128k. There are five cards installed on the back plane accessable from the front of the unit. They are: 1. ES Controller (with a 6809 on board) 2. ES Controller Memory 3. Trace and Break 4. ES Ram Overlay ver. 2 5. 68010 08/00 Emulator Anybody familiar with it? I also got two Dec boards: M7164 (it has 4 AMD2901 bit slicers on it) and a M7165. I'd happily trade both of these for a M7260 that I could dearly use. And last but not least found is an boxed A MAX, the Macintosh Emulator for the Amiga with the Apple ROMS but missing disks. Does anyone have this software? Thanks and beware the bunnies... - Mike: dogas(a)leading.net
