HP-9815 and interface ROMs, revisited

[John Ioannidis]

Has anyone ever dumped the ROMs of the 9815 (both models), and the various interfaces? I know about the source listing in the original patent disclosure (4,089,059), but there must have been changes over the years, esp. in the S model.

FWIW, the "missing" ROM on the -A model was supposed to contain printer bitmaps for Japanese. I would assume that's what the top 2K of the second ROM of the -S model contain, but I haven't verified it yet.


Thanks!
