Stan,
Why? Are you thinking of bidding on the one on E-bay? I was interested
in it but I was waiting for the price to come down. It's been posted there
about three times.

Hello all,
I have a few questions about the HP 9831A BASIC language desktop
computer:
1) Did it use the same plug in interface cards as the HP 9825 series?
From what I've been told it should but it had most of the ROMs built in.
2) What sort of plug-in ROM cartridges or other options were available
for it?
None that I know of. There are no ROMs specificly for it in the '78
catalog. That was the only catalog that listed the 9831. It *may* use
standard ROMs but I don't think it needed any.
2a) What would happen if you plugged in an HP 9825 series ROM?
I don't know but I can give you Steve Leibson's address and you can ask
him. You do know who he is don't you? From what I was told, you cold plug
in the 9825 system ROM drawer and it would become a 9825!
3) How long were they produced? I found them listed only in my 1978 HP
catalog.
That year only AFIK. I have a 9831 but I've never looked at the date
code on it. The one on E-bay is only the second one that I've ever heard of.
Take a look at "http://www.intellistar.net/~rigdonj/9800.htm". You
might find it interesting.

Thanks!
