  Somebody should disasemble the firmware of these HP

 be iimpossible, the firmware EPROM is the only programmed IC (no other
 PROMs or PALs or anyhting like that), there are no custom ICs (the disk
 controller and HPIB chip are standard, the processor is a 6809) and there
 are cheamtics so the addresses are all known. Then we'd know for sure

Where is information on this, including the EPROM dump?
