Jason, I think the problem is that the original version of TRSDOS you are using
will not accept a date after 1989.
As you say it boots fine to a date prompt..
You will need to get LDOS to correct this funny flaw in the operating system.
Guess They never expected them to be around so long..
But it sound like you have it working..

Hello everybody.
I'm in the process of restoring a submerged TRS-80 Model III. It was
sitting in my friend's basement when his septic tank backed up (yuk.), and
it was sitting on the basement floor (double yuk.). However, his solution
to fixing it was to drag it up the steps on sheet of plywood and let it sit
in the rain for three weeks. Then he gave it to me because he was afraid
to plug it in. I started by taking it apart, and hosing the whole thing
down. Then I took all the boards out, and set them in front of heater/fan
to dry (low power). I did the same to the disk drives, the keyboard, and
the picture tube.
After everything had dried for about a week, I put it all back together,
and turned it on. The tube came on with a bunch of crazy characters on the
screen. I took the main board out, propped it up behind the computer,
tried it again, and the screen came up with the "Diskette ?" prompt. I put
in a copy of TRS-DOS (unsubmerged), and hit reset. ERROR came up in
40-column letters. I shut it off, and pulled the drives. I stuck (well
more like jammed- it was too wide) a 5.25" 360 half-height drive in it (it
ended up at an angle and upside down to fit), and tried that. That time it
worked, booting to the TRS-DOS screen, asking for a date. I typed
"09/01/98". Nothing. I took a key off the keyboard to try to clean it,
and they are the sealed-switch type. I had to unsolder each switch, take
each one apart, clean it, put it back together, and solder it back to the
board. However, I just cleaned the <1>, the </>, and the <Enter> key-
enough for me to enter the date. It worked.
Now's where I need the help. Here's what I need:
-5.25" full-height 360k disk drives (any type but Apple - doesn't need to
be TRS-80).
-External TRS-80 disk drives.
-Cable to connect external drives to the computer.
-TRS-80 Model III hard drive (can be a clone)
-Internal cable connecting RS-232 adapter to the main board.
-TRS-80 Model III software (can be on tape or disk)
I'm also looking for anything for the CoCo Model I and II - ESPECIALLY disk
drives and a printer.
As always, ThAnX in advance,
