Hi Guys,
Have a TRS-80 Model II which I am planning to restore (probably
get started over the holidays) - but one thing I am going to
need is a boot disk. Anyone out there got a working Model II
system? (This is the big "business" version with the single-
sided 8" drive).
Regards,
Dave
PS: Also still looking for a Cromemco System-3 boot disk.

Hi Rich,
Since no-one else has repsonded, I uncrated my 8800 and measured the switches.
This measurement is difficult, because the top of the collar does not protude
through the front panel, and in fact does not come all the way through to the
face of the panel.
I measured the switches by holding a toothpick against the top of the collar,
and straight out beside the switch - marking the top of the switch, and then
measuring the toothpick. Measurements are from the collar to the furthest out
edge of the dome at the end of the switch handle.
Both switch types (two position and three position) are exactly the same length.
I measured the two position switch by positioning it 1/2 way (straight out) .
And the measurements are (drum roll please):
11mm (7/16 inches)
Regards,
Dave

To the half dozen+ listees who responded to my listing this computer as available in November: The guy who had the Eagle has certainly moved out of his apartment by now - as it is well after the first of the month. I presume the box went to computer heaven and we were not able to rescue it. I guess that's the way things go sometimes. Thanks to all. Bill.

I'm looking for an M9312 bootstrap ROM for an RX01 drive. I believe the DEC number on the chip is 753A9. Does anyone have one of these that they would be willing to get rid of? I have other M9312 ROMs to trade.
Thanks,
Ashley
I got the last box of junk from my brother, and just inventoried
the floppies, going by the labels. I likely have errors in
sidedness/density but they were all made on one of two CP/M
machines; I have one here and the other (my father's) is still
in Mass and I can get it if necessary.
I have no idea whats actually on them or which ones are readable,
that come snext after I power up the cards. I've gone through
the chassis already and it's fine. I'll probably do smoke
tests today.
There's some good stuff I think. BDS C, CBBS from 81 (sources
plus BBS files), Stackworth FORTH, JRT Pascal, some other
Pascal, Aztec C, FORTRAN IV (likely TDL/Xitan), F80, M80, L80,
etc (m'soft) basic compiler (ugh) old DBASE, etc...
I'll make everything available ASAP.

I'm looking for a DECstation 5000, a fairly recent and marginally
classic MIPS workstation DEC sold in the early 1990s. (Well,
it's classic to me for nostalgia reasons, but I won't get into
that). I'm specifically looking for a 5000/133 or /150, but
really any 5000 will do.
I'd be happy to pay shipping and a reasonable price (reasonable being
something in the < $50 range, since that seems to be the going rate),
and/or I have a MicroVAX 3100 (desktop case, 16MB RAM, 1GB disk,
8 serial lines) I'd be happy to trade.
If anyone has a lead on one, please let me know!
-Seth

Those keyswitches are actually contacts that need a special tool for
replacement. I used to do hundreds of them at Dataterm Inc. They still have the
contacts and inserts for those keybds.Give them a call @ 781-938-1010 or e-mail -

Hello, all:
If anyone has access to an Altair 8800 (the original model) and can
measure the toggle switch handles, I would greatly appreciate it. I need the
length of the handle from the top of the threaded collar to the end of the
handle.
Thanks a lot.
Rich
Marty Greene,
There are others of us who have TI 990/systems in storage. I have 2 990/10 systems. DX-10 OS with 10M cartridge (CDC?)drives. Mine came from a Paradyne Corp Modem Analysis system tracking 300 Paradyne 2400 Baud multi-drop circuits on an 800 hz subcarrier over dedicated lines. So I have lots of serial ports...Each modem had data and an analysis port.
Sincerely
Larry Truthan
I may also have a Xerox Sigma diagnostics tape and or journal somewhere in the basement.
