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

The Eurplus is basically an Apple II+. Thus, the "plus" in its name.

It's very likely that no commercial utility will work on this board, it
probably shipped with its own chipset-specific drivers.
There were some alternative drivers such as The Last Byte, but they worked
only on certain 286 chipsets (e.g. C&T)
Kai (for whom EMS was once a technical specialty, boy that brings back
painful memories)

We'll try anythig until he gets it right. At one time this stuff was so
commonplace that even after years with it I forget what and where.

With these beasts I was also given a centronics printer cable but there
seems to be nowhere to plug it in. Is this something which also needs an
interface card?
