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 <

Yeap, it was only listed in the 1978 catalog.
