yep, the ad in the paper said 'free osciliscope and electronics parts' Tony would have had a boner at this one. I picked up a nice Tek 422 scope with 3 probes, and then filled the car with boxes of TTL, and every other type discrete electronics, a few power supplies and a few other goodies packed within. There was a boxed Imsai PIO-4 and a few other s100 cards (8k static and a few wirewrapped z80 processors). There were a few incredible chips in pile that the foam really screwed up... check out: http://bellsouthpwp.net/d/o/dogas/chips1.jpg There was a ceramic C8080A with the pins completly eaten away , a Ceramic MOS 6532 that faired only a little better, a ceramic/traced AMI 6810, and a early plastic 6502 and 6530 among the more conventional stuff. Any recommendations on neutralizing/cleaning the gunk of the ceramics? Oh yeah, then there was the boxed SD Z-80 Starter Kit SBC with manual and cassette. A sweet little sbc with 2 s-100 slots (installable) but I had to buy that one for $8 It has been a long dry season and all I can say is its about damn time. ;) - Mike: dogas at bellsouth.net

Intel 80286 "DCU" Multibus system

Definately looks like some variation on a 310 to me.

speaking of Intel computers - ARPA DOT?

by rigdonj＠cfl.rr.com

I was out scrounging yesterday and found an odd looking computer (I THINK it was a computer) with a name plate that said ARPA DOT. Any idea what this is? It was heavy aluminium case about two foot high and about 8 inches wide and about 2 foot deep. The top edges were cut at 45d angle about 1" high and the bottom flared out about 1 1/2" on each side and the case was painted a dark grey. On the bottom front was a brass name plate that was screwed to the case. The name plate said ISSI Intel ARPA DOT and was arranged like this: ARPA ISSI Intel DOT The case had two large vertical card solts that opened in the front. The one on the left had a 3 1/2" hard drive in it. The one on the right was emply but looked like it held the CPU, memory etc. There didn't appear to be any electonics in the case except for the power supply. The "drive board" had a small HD SCSI connector on the front but there were no other connectors on the outside the case except for one for an AC power cord. It was definitely unique looking but since the main board was missing and I had a full load I passed it up. I TRY to keep my digital camera with me for opportunities like this but I was driving a different car and didn't have it. Joe

You lucky dog! Dammed shame about those ICs! Are you coming down for the hamfest?

HP 6020i SureStore drive

by charlesmorris＠direcway.com

My ten year old HP 6020i CD-Writer drive isn't working properly any more (frequently gives "Power Calibration Errors" while trying to write a CD-R). I've never worked inside these drives and for only 2X write speed don't want to learn. I just got a 52X drive for $23.99 and the difference is dramatic (2 minutes to burn a CD vs. 38 minutes!) Anyway, if anyone wants it, with the manuals and installation CD, they can have it for the cost of postage, otherwise it's going in the trash... thanks Charles

IPC manuals?

by aek＠bitsavers.org

> Does anyone if the HP IPC manuals are scanned and posted online We exchanged some mail about it, but I needed to clear the backlog of 98x6 stuff first. I have the service manual scanned, but it isn't on line yet.

M7821 module schematic

by aek＠bitsavers.org

Did some digging.. You can find it on pages 76 and 77 of the RP11C controller schematics RP11-C_schemMay73.pdf I'll extract the pages and add it to the M-series module schematics on bitsavers.

Old Computer Collecting vs Electronics Building

by dm561＠torfree.net

Date: Fri, 3 Feb 2006 01:56:23 -0500 (EST) From: der Mouse <mouse at Rodents.Montreal.QC.CA> Subject: Re: Old Computer Collecting vs Electronics Building >> There really should be a requirement for >> licensing of computer owners/users - if you can't prove you can >> secure a machine properly, you don't get to own one... >It's only when they connect to the net - or want to take them on the >public roads - that there's any reason for the State to get involved. You're soooo right!!! We have waaaayyy too much freedom and not nearly enough State control!!! Programmers should of course also be licensed and only State-approved languages and programs should be permitted. You should also not be allowed to access the 'Net with anything other than an Intel-inside PC-compatible meeting State-approved specs and running State-approved security software (with built-in provisions for bypassing and access by any State agency that wants it, of course). I'm sure this would stop every hacker & virus-writer cold, just like our billion-dollar-plus (original cost estimate: 2 million) gun registry has eradicated all gun-related crime in Canada (especially here in Toronto). Oh, wait - no, it's actually more or less tripled since they brought that in; hmmm... Love the caps on the State, BTW; puts it right up there with the Big Guy/Gal where it belongs... Sheesh... and I made a New Year's resolution to never again get sucked into and contribute to one of these moronic elitist threads... Sorry. mike

MS11-LD (M7891-DA)

by waisun.chia＠gmail.com

Quick one: Can I plug a M7891-DA into a 11/44? This is supposed to be 128kW MOS RAM for the 11/24 and 11/34A... BTW, what kinds of memory options/expansions does a 11/44 have?

OT - Need fuse and jumpers from APC battery pack

by nerdware＠ctgonline.org

Those of you in data centers that may have a dead APC lying around... Someone donated a Smart-UPS 1000 to our theatre. Dead batteries, but otherwise it's good. I ordered a set of replacement cells from a 3rd-party vendor, but when I went to pull the dead cells, one of the wire jumpers that connects between the cell terminal and the blue 60A fuse was all corroded from leaked battery goo. And I accidentally cracked the fuse while trying to extricate everything. I know I can get the fuse at the parts store, but I don't think I'm going to have much luck finding someone at APC to send me one jumper... Anybody have a dead UPS that you're about to scrap that has the fuse assembly you'd be willing to pull and part with? You can email me offlist.
