Hey everyone, I just wanted to announce thta I will be opening a new
Rainbow 100 website on Saturday, Feb 8. The site is located at:
http://www.classiccmp.org/rainbow
Right now, all that is there is an announcement. I hope everyone will
take a moment top visit once it's open.
I haven't been keeping up with everything in the Rainbow commumnity. I
noticed that all the schematics have been posted on the Update
(ftp.update.uu.se) archives. Who took the time to do this? I just wanted
to thank them. Anyway, visit the page if you get a chance! Thanks!

I recently won an auction described as a "Science Fair Junior
Electronic Lab 10 in 1"... the picture showed a couple of
blue grid boards which were, AFAIK, not part of a 10-in-1
It turns out that in addition to the 10-in-1, there was
an entire (and a partial) "Science Fair Junior Project
Board Kit" (cat no. 28-153) - one manual, two plug boards,
one IC board (14-pin socket + 14 springs) plus a double
handful of mixed loose components.
The components are somewhat interesting from a historical
perspective - there are several flavors of transistor sockets,
several segmented LED displays (some on PCBs as from an LED
calculator, some in DIP form), mercury switches, reed switches,
and a bag of resistors with a "King Kits" card from Poly Paks.
I'm curious if there's a repository of ancient Radio Shack kit
manuals out there - I did not get a manual for the 10-in-1
(cat no. 28-225), but at least I got its box (covered in packing
tape, grrr.)

Those chips are:
DEC 21-17311-01 or 21-17311-02 = T-11 processor
DEC 21-17312-00 or 21-17312-01 = DC 319 DLART
DEC 57-00001-01 = KEF11 FIS
DEC 57-00000-01 = Ctrl/Data Hybride of 11/23
DEC 21-15542-01 = MMU of 11/23
I have those parts over here, and since both the original poster and myself are
located in Germany, I have already dropped them a line and helped them out.

I've hacked together a 2.11 BSD C program (nothing special, should work
on other *nixen) that takes a .tap tape file and spits it onto a real
tape. I've tested it with both a TK50 and a TS05 tape drive. It even
successfully wrote a bootable TK50 format XXDP 2.5 tape. I'm going to
be cleaning up the code and posting it on the web, but for those who
can't wait, here is the raw code. It is left as an exercise to the
reader to figure out where my MUA breaks the source code lines.

I want to work my Art EPP-2 programmer but i lost the software
google doesn't have what i'm looking for
any of you pherhaps
(its for the 27 and 28 series)

Finally found a Wang VS-85. Had to take it apart to get it in the house!
I'll be putting up some information and pictures on my web site soon.
The power supply had been removed, so I hacked together some cables and
used a power supply from something else. It has 1MB main memory, an I/O
controller for 16 serial (Wang coax-connected devices), four SMD disk
ports, a tape drive controller, and a couple of other unknown I/O
controllers.
The most interesting part:
A CE manual, describing the CPU architecture, theory, and lots of other
useful stuff, along with complete schematics for the whole system, and
most of the I/O controllers.
This machine is 32-bit, with an instruction set similar to the IBM 370.
The CPU consists of a ton of TTL chips, an ALU made of 74181's, and an
8KB writable control store. The microcode for the CPU resides on a 5
1/4" floppy disk. The floppy disk drive in the CPU cabinet can only load
microcode, you can't use it to store data.
Each I/O controller has its own CPU (or several). The old ones have a
couple of 74181's and EPROMS with a control program, the newer ones use
Z80's, and have RAM only, the control program gets loaded to them when
you IPL the system.
It's about the size of a clothes dryer. The standard power is 120vac,
but the hacked-in power supply is 220vac. Draws about 4 amps @ 220vac.

I have one of these boxes. It appears that IBM took another PC case off the
assembly line, stuck in a power supply and a passive backplane. There are
two interface cards, one for the PC and one for the expansion box, connected
by a very stiff cable -- don't recall what's on them but probably buffering
ICs and the like. The cable is about 3/4" in diameter. It terminates in
D-shell connectors but I don't recall the pin count (probably D50). The
stiffness of the cable borders on inflexible and mine pops-out of the metal
shell constantly.

They are a box with a passive ISA back plane and a pair of ISA cards
that are connected with a single round cable about as big around as
your thumb. The box itself is styled like an XT (down to the sloping
front).

I'm looking for an 8" SMD disk drive. The only ones I've seen were made
by NEC - and I can't seem to find any. What other companies made these
kind of drives? Any suggestions on where I should look or what (other)
kinds of equipment these were used in? (besides Wang minicomputers)

Well, in the process of going through my computer room, and sorting
stuff out to keep, and get rid of; I've decided to get rid of 3 of my
classics. They've sat around for too long, going unused. So...
--- VaxStation 3100 m38
- 32MB RAM (maximum!)
- 600 MB HDD in matching Storage Expansion Unit
- mono video output
- VR262 monitor (Don't think it works, might be a minor repair)
it does drive a Digital VRT-17 fine on the green channel fine, though.
- Installing & Using the VR262 manual
- cables & power cords - including a MMJ cable & MMJ-DB25 adapter
- 2 keyboards (IIRC LK201) - I'll make sure they work first...
- Owner's binder - Customer Hardware Info/Planning & Prep/Owner's
Manual/Network Guide
- NetBSD 1.5 is currently installed
--- C-128 & Atari 800
- both have 5 1/4 floppy drives, power cables, joystick
- Bunch of games and apps
Best offer. Pick up in New Haven CT preferred (especially for the Vax).
The C-128 and Atari should'nt be that bad to ship, though.
Cash, money order, PayPal. For trade, I'm looking for SCSI & IDE HDDs
over 4GB, true-parity memory, PC100/133 DIMMs, P-III 800 CPU, 19"
monitor...
