This is obviously a panel for a corporate cabinet. I've also seen a picture of an alleged 11/74 that was in a corporate cabinet. However, the one picture I've seen in real life (as opposed to on the internet) of an 11/74, it was in full height 19" cabinets with the traditional maroon/red color scheme. Also, I am under the impression that a CIS was never completed. That would have required the KB11-E. The only 11/74 CPU I know was done was the KB11-Cm, which is a modified KB11-C (aka 11/70). This won't allow you to add a CIS option. No place nor wiring for it. Does anyone know *for sure* that the KB11-E was made, or might this front have been a prototype for a possible KB11-E, but in reality used just with a KB11-Cm?

Glockenspiel C++ or CFRONT sources

by RMeenaks＠olf.com

Unfortunately, not. But there is an alternative which I havent tried. If you are willing to pay $900 or so, you can pick up the cfront sources >from AT&T. Also, SUN has a GNU C++ to GNU C translator on their website which might help as well...

Company previously used a, now deceased Apollo workstation with Domain 2.1.0. But its not working any more, so have managed to move all but the C++ to C translation onto the Microsoft development platform. If you get any feedback I would appreciate it.

NeXTstation TurboColor find

by nospam212-cctalk＠yahoo.com

Today I received a NeXTstation TurboColor, with full doc, original boxes, NeXTstep 3.0-3.3, 17" Color Monitor, Laser Printer, Modem, set of NextWorld magazines, various books and doc and tons of software. It was shipped down from Canada and arrived in my office where a co-worker looked at it a moment, then looked at me and asked, "so when was that state of the art?" :) Now to catalog, setup and add to my site.

Building electronic projects from 30-year-old articles (was Re: Old Computer Collecting vs Electronics Building)

This sounds kinda > cool! And a nice way to get a little experience without damaging > anything hard to find. http://www.incolor.com/bill_r/elf/html/elf-1-33.htm I even used real HP displays (electrically identical to TIL-311s, but in a different package) and 1822 (5101) 256x4 SRAMs. If you are shooting for software compatibility without a slavish devotion to the 1976 appearance, you can use a modern 32Kx8 SRAM and even add a latch to access memory over 256 bytes (but toggling in that much data is kinda tedious). You will find it hard to locate a genuine 1861, but Spare Time Gizmos has a modern 1861 pin-compatible emulator (a shift register, a counter, and two 22V10 GALs) that fits in the socket for a real 1861. If you don't care about video, you can get a newer 1802 processor and run the entire thing at 5MHz. For those that don't know, there's a reasonably active 1802 group on Yahoo... http://groups.yahoo.com/group/cosmacelf/ ... I'd recommend it if you want to play with the 1802. -ethan

Affects of moisture (or lack thereof) on components

> > Does anything bad happen to electronics that are stored in very dry > > conditions for long periods of time? Cities like this would be anything > > in Utah, Arizona, Nevada and Idaho (Salt Lake City, Las Vegas, Phoenix, > > Boise, Reno, etc.). Other than ESD which has already been mentioned, if the device relies on any rubber components (like capstan rollers) the dry heat might cause them to dry rot. Same for grommets. However, the USAF seals up its old planes and stores the in "the boneyard" at Davis-Montahn AFB in Tucson, AZ, so it can't be all bad.

free stuff

by CaptnZilog＠aol.com

Found another box of TK50 tapes, so figured I'd ask again if anyone is interested, contact me. Also have a couple of external SCSI tk50 drives I could part with, and a VaxStation2000, with a 19" vax monitor (monitor is probably prohibitively expensive to ship, but anyone near CT who wants both, and keyboard/mouse, etc, I'd give preference to parting with both together). Also tons of 90M DAT tapes, if anyone is interested. Also for anyone near CT, I have a compaq 1600, dual 600mhz cpu's, all 5 drive trays (one 4gig drive dead, but I think I have one to replace it with), and I'll toss in a 3200-raid controller. Free to anyone who wants to pick it up, or meet someplace. I'd consider shipping it if someone wants to cover the shipping costs. And a pair of Mac IIsi's, and three MacSE/30's, all with NIC's (at least one of the SE/30's has NetBSD on it). Free, just looking to clean house (keeping my quadra 650). And anyone who might be looking for TEK service manuals, the old job was tossing several xerox-paper boxes of them out, I'll try to make a list, but if you're looking feel free to ask. Also have some plugins for the 7000 series O-scopes, probably take a few bucks for those, but I can certainly come up with a list. -- Pete

A good BASIC version for an IMSAI

by rcini＠optonline.net

All: I'm looking for recommendations for a good version of BASIC for my restored IMSAI. It's a Z80-based machine with 48k and a serial console. Ideally I'd like it to be ROMable. I have copies of the original TinyBASIC, Lawrence Livermore BASIC, Minol TinyBASIC, Denver BASIC, and a BASIC from Dave Dunfield. I haven't slogged through the source for each yet but I'm hoping someone can point me in the right direction. Thanks.

best yardsale in a decade

by dwight.elvey＠amd.com

Hi I think the corrosion is from sulfur in the foam. If so, I'd suspect it to be an acidic corrosion. After cleaning with something like vinegar, following with some baking soda might be a good idea before the final washing. This should help neutralize any remaining acid.
