Not so many, others do have far much more than I have.
My little collection:

PDP 11/34a with 3 RL01's running RSX-11M 4.2, 4.4 and 4.5
PDT 11/150 running RT-11
Mac powerbook 170
HP model G40
VT100, VT520 terminal

Nop. There have been at least 2 major public releases
other than 1.25. 1.0 and 1.1. 1.0 was the first public
release for the IBM PC and 1.1 added new disk types.
1.1 and 1.25 are almost identical - 1.1 was the IBM
version, 1.25 the OEM version.
If you're searching old versions (maybe prior to 1.25)
you should look for things like Z-DOS (Zenith), 86-DOS
(back licensed MS-DOS to Seatle Computer products),
SB-86 (Lifeboat Associates) or COMPAQ-DOS (guess who :).
Maybe a bunch of other names I don't recall right
now, since MS licenced it to any 8088/8086 computer
manufacturer available.
DOS 1.x was still machine dependant, since the BIOS had
to met the hardware. DOS 2.0 and up added new disk types
and loadabel device driver.
With 2.0 Microsoft tried to establish their own trademark
MS-DOS as OS and scraped all OEM licences or at least tried
to cut of the different names. After 2.0 only IBM kept the
private name of PC DOS.

D'oh!
I downloaded the schematics and am trying to figure out what's up with
this thing. Strange thing is the part marked Funt. ROM (U 36 I think) is
empty! I'm wondering if this is supposed to be the case.

Well, the computer repair company I worked for used to do alot of LCD and
laptop repair. Alot of times the lines are either easy to fix problems w/
cables and little wire connectors, and other times they are just on their
way out ( i repaired servers and desktops so I never got to dabble :/ ) in
any case, a good place that does *VERY* reasonable LCD and laptop repair is
Matrix International, which i believe is www.matrixintl.com, or... I've
forgotten the phone #, but they are in Austin TX. they used to do flat rate
LCD repair for us for 125 a system.

Picked up at a yard sale today, in Framingham, Ma.
IBM P/S 2, Model 50Z
On-Site Computer Systems box... Unit seems to have two hard
disk drives, that, on the outside, remind me of the old RD54
(I think) that used to be in the old DEC PRO-350's, two LPT
ports, and one serial port. Also a 5 3/4" floppy drive...
Anyone ever heard of these people, or know anything about their
stuff?
3 Monitors, one NEC, one Samsung, and one Tandy.
A Citizen MSP-20 printer..
Cost of this "rescue" US 20$, and the people even helped
load it into my car..
Now to sort it all out, and see "what works, and what don't".

To date I've successfuly opened and fixed maxtor2190s and Micropolus 1325s
wit HDA difficulties. I've run a RD52 with the cover off as a demonstration
and I have somewhere a 16 year old st506 with a lexan topcover for viewing.
It all boils down to what was the failure and is it fixable. The latter
can be hard as platter assemblies and generally "glued and screwed" and
tend to be hard to get apart. Heads are small fine things easily broken.
If the media is scared it's a total as the metal will be everywhere and
some fo the metal like the head cantelever is steel so all that steel dust
is now in the magnet assembly for the positioner... Not impossible but
there is a certain amount of pick and choose in which one to fix.

Since the average XT PC doesn't use DMA very intelligently anyway it was
not much loss.
