Third rescue, to me, was the best: I now have a

Hewlett-Packard 9831A desktop computer. This machine uses
the BASIC language, has a single-line LED display and accepts
most of the 9825 interfaces. I know Tony has one of these, but
I'm not sure if anyone else does.
I have one and I know of two others, not including yours. The 9831 is basicly a HP 9825
with ROMs from the HP 9830. You can actually unplug the 9830 ROMs, plug in 9825 ROMs and
it becomes a 9825 again. One HP engineer that I talked to said that they used to keep both
sets of ROMs on hand and switch them at will. One of the really nice things about it is
that it had all the optional 9830 ROMs built in. See
<http://www.classiccmp.org/hp/hp9831.htm> for more info.
They only appeared in the HP
catalog for one year and are extremely uncommon.
Yeap, it was only listed in the 1978 catalog.
