Can anyone help this fellow obtain a most ancient version of DOS?
Please contact him directly if so.
Thanks!

Spam is bad. Spam is theft of service. Spam wastes resources. Don't spam, period.
I am a WASHINGTON STATE resident. Spam charged $500.00 per incident per Chapter 19 RCW.
I thought I'd put out a warning about the Teac FD-55BV-16-U 5.25" floppy
drives. They seem to be totally unsuited for anything other than reading
MS-DOS floppies.
I bought one a couple months ago, for a project with my Amiga, since they
were what the developers of the Catweasel board recommended. Spent about
two days trying to get it to work. Finally I pulled the drive out of my
486 (an older Teac drive) and it worked immediatly. Assuming the Amiga
part of the equation was the problem I put the new drive in the 486.
Well, yesterday I needed to make archival images of some RX50's. No dice,
it absolutly would not read them. I'd picked up some older Teac's at the
last swap meet, so I got them out, and after two that only semi worked I
found one that works just fine, and was able to make my images, copy them
back to new floppies, and boot my PDP-11/73 off of them.
Note, I tried using the Teac FD-55BV-16-U drive with both 'putr' and
'teledisk'. Neather would work with it.

Can you trace the circuit of the buffer chip to see at least what pins are
outputs to the 2716 (addresses) and what is from the 2716 to the adapter
(data lines)?
Another choice is a '125. A '242, '243 only have the data inverted from each
other, so if one's the correct chip, the other won't cause logic conflicts,
just wrong polarity signals.

Well, thanks to the answers I got on my questions I've got a bit better of
an idea on how to proceed with getting the newly built from parts /23 up
and running, and I understand why I was having difficulties (as I thought,
the path through the backplane).
Since I'm using a RQDX3 for the drive controller, it sounds like my best
bet is to forget the RX50, and go straight to RX33 drives. However, based
on my taking an additional look at the RX50 drives I'll probably try to get
them up and running. What can I say, they're just too cool looking :^)
The QD614 board for emulating RL01/02's sounds pretty cool, to bad I don't
have the software for formating the attached drives.

Why not just run... What's that DOS program that fakes out apps to make
them think they are running on another version of DOS? I'm drawing a blank
here, but I did use it one time to make Windows 2.03 think it was running
under DOS 3.3 when it was actually running on DOS 6.0. Worked great. The
command is documented in the DOS help file, 5.0 and up, IIRC.

While browsing I discovered that Chapter 9 of TAB book # 1183,
"Troubleshooting Microprocessors & Digital Logic" by Robert L. Goodman,
consists of about twenty five pages of schematics and troubleshooting hints
for the TRS80 Model 1.
I hope this is of interest.

No, that's NOT what I said, to make it easier to understand:
1. remove the round PC mount power socket from a dead 64 curcuitboard
2. remove the Plus/4's square power socket from the Plus/4 curcuitboard
3. solder in the 64 socket where the Plus/4 socket was (the pin locations are
the same)
Then plug in any 64 power supply to the Plus/4 and fire it up. Works like a champ!

Really more work than is really worth it. The plus/4 supply is a black
Commodore 64 brick supply (the one with the bah-relief C= symbol) with a
square power connector, no major cosmetic difference.
since he wants the 'real thing' check out:
http://www.vintagecomputer.com/
where you will find these prices:
4. PLUS/4 WITH POWER SUPPLY.....18.95
5. PLUS/4 COMPUTER (KEYBOARD).....10.95
*** 6. PLUS/4 POWER SUPPLY.....10.95 ***
7. C16 WITH POWER SUPPLY.....24.95
8. C16 COMPUTER (KEYBOARD).....14.95
9. C16 POWER SUPPLY.....14.95
