Some 12?s came with the card cage in it, it depended on luck mostly.
So what I never really looked at closely and warehoused could be 12 or
I know not an model 2 as it was not silver like the trs-80 model 1 in
the collected here on display.
I have scanned the manuals that came with my Ford-Higgins Powerframe
machine. It is a QBUS PDP-11/73 machine in what looks a whole lot
like a DEC BA23 enclosure. Not sure if it's a clone or a licensed
rebadge. The CPU board is DEC, the memory is a Clearpoint P/N
3325/300 (size unknown) and the disk controller is a Dilog DQ215 P/N
33214701 (SMD?). It has a combo fixed-disk/cart drive that their docs
call an RC40. That looks like a DEC part # but doesn't seem to be
anything they made.
There's very little out there about them (I found a 1992 Usenet post
>from someone asking "what is this thing??") so I wanted to fast-track
these docs online.
And some photos: https://goo.gl/photos/DiXaiiMKXNorGqzVA
The machine has been given to a friend in search of a QBUS project, so
I don't have any more pics at the moment.
I recently impulse-bought a paper tape reader from eBay, a Remex
It has several enormous capacitors in it and I want to do my due diligence
before powering it up. Does anyone have advice in this regard? I'm
competent in soldering and rework of all sorts but definitely more in
digital than analog.
Also the spindles squeak very slightly - are they oilable?
In general it looks to be in pristine condition; no dust and no magic-smoke
smell. The only repair item I can find is a sticking tape roller and gentle
bending oughta solve that.
I await your thoughts!

The bitsavers archive is 267 Gbytes.
So at 4.7G per DVD, it comes out to almost 60 DVD's.
I remember a PDQ Bach radio quiz show where the prize was The Wagner Ring Cycle on convenient 45 RPM records.
Ive been extracting data off a 3.5 inch windows XP-formatted floppy disk
with many bad sectors. The odd thing is it's always the same bad sectors
on every track. Such a 3, 8, 12 and 17. Once or twice it might be just 3,
8 and 17. Or occasionally 3, 8, 9 12, 17. This patten is the same for
every track. It's (more or less) always the same sectors that are bad.
Why? I can't believe natural degredation would be so consistent. Anyone
have any thoughts?
I've imaged (with ImageDisk) some floppies I've got with my "new" 8560
You can find them at
Among other things there are cross-assemblers for 68000, 6809, and 6800.
From the TNIX installation disk set one is missing (disk 5 of 5).
I'm looking for the Z8000 cross-assembler for TNIX.
Does anyone have it?

Interesting coincidence. I was digging through some boxes of stuff yesterday, and I came across two sets of these in really nice condition. Haven't tested 'em yet (had /no/ idea that they could be used for diagnosis of an RX01 control board) but looks like they should be pretty simple to check out. I had didn't know of the existence of these before yesterday. I did a little searching and found that they are useful for debugging 11/35 and 11/40 systems, as well as RK05 drives...but didn't see anything about the RX01 drive electronics.
Speaking of RX01's, does anyone out there have a spare front bezel for the RX01 that they'd be willing to part with?
I have a working RX01 on my 8/e system (both drives good, amazingly) but the bezel was missing when I got it.
It'd be nice to have, as it looks rather dumpy in the rack with the rest of the system.

Actually, not me! I'm an old enough campaigner that I recall when real light
bulbs were standard, and they were a total PITA! So when LED's arrived, we
all though they were the greatest thing since sliced bread. So I'm now very
happy with my LED-equipped KM11 clones - I still have that anti-bulb bias! :-)
