I found the manuals for the TBG on www.spies.com/~AEK . Haven't messed with
that board yet but, shouldn't have too much trouble using it.

As with the TBG board, I found the manuals for this board. There are several
code samples with the manuals and on Jeff's site but, so far I can't get it
to work. I didn't realize the cable had to be changed for RS232. If you have
the pin outs, that'd be cool.
I don't have the code in front of me but, unless I'm mistaken, it just
continously loops when checking the status. Not sure if this could be caused
by the cabling differences or not.

JMP *-1

NOTE: This is the only I/O card in the box so, I assumed it had to go in
slot "10".
If you can provide a short routine to send a single character to the
console, that'd eliminate one of the variables (me).

No problem. Got plenty of dumb terminals laying around.

We'll get to that a little later :-)

Was able to locate the DOCS for the ROM on the /~AEK/ site and ran the
diagnostics (as indicated above). Everything checks out OK.

Hmm... Once I get the system talking to a serial interface, I'll investigate
further. From what I understand, the TAPE READER protocol is pretty simple
so, I may be able to hack something together. I'll let you know when I get
this far.

I have several HP 7978 (HP-IB) tape drives that I use on my "classic" 3000s
and 9000 HP-UX boxes. Those are really sweet drives! Not sure if they're
compatible with the 1000 or not?

Downloaded the assembler (hpasm.c) from Jeff's site. Had no problem
compiling or running it on my 9000. I've been using it while trying to get
the serial interface going.
Also downloaded the e21.c emulator but, wouldn't build on my box.

Really haven't had time to investigate.
Thanks again, SteveRob
