I only have the PC1 but, the Australian HP museum
seems to have one
http://www.hpmuseum.net/display_item.php?hw=133 .
Achim Burger knows how to dump the ROM contents without opening the case, he
It must be possible to read out the ROMs without opening the mosdule,
after all ,thats; what hte HP9800 does when it runs said programs. In
fact, the only signal you can find internally and not on the moduel
conencotr is the -V Vbb bias supply (there's a -12V rail on the conenctor
and a potential divider ins the mdoule). The module, as I am sure you're
aware is just 4 of those HP512*8 ROMs and the potential divider.
made some small programs to do this and copy the
contents through the rs232
interface.
Such a program would ahve to be in machien code, and there's no way to
enter machien code o nteh keyboard on any of these machines. I guess he's
got something on tape or cards to do it. Eitehr that, or he grabs the
data from the M and T registers when the machine does the power-on
memory scan.
Maybe you can do something with this info.
I will contact Achim (do you have his address? it's remarkably hard to
find), but I don;t hold out much hope. I suspect he'd like all the ROM
images for his HP9800e emulator (said package includes PC1 for the HP9820
and DataComm 1 foe the HP9830) and I would have thought he'd already
asked the Australian Museum.
Incidentally, if you want to know what I want it for, no I am not running
an emualtor. Or writing an emualtor. Take a look at the talks on the
Sunday of the HPCC conference this year :-)
