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.

From what I've been told it should but it had most of the ROMs built in.

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.

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!

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 "

might find it interesting.
