I picked this up with a bunch of other HP
equipment and some Apple equipment for $50. I thought they had some
drives for it but the drive unit (HP 9121 Model D) seems to go with a
different system. It has some cartridges plugged into the rear. An
82909A 128k Memory Module, an 82908A 64k Memory Module and an 82936A ROM
Drawer with these roms; 15005B Advanced Programming ROM 1 & 2,
15003A I/O ROM, 15002A Plotter ROM, 15012A Electronic Disk ROM, and a
15004A Matrix ROM. Can anyone tell me anything about these? If anyone
has any doc or software for these I'd like to
hear from you. I could also use
some external storage system or an HP-IB interface so I could use the HP
9121 drives. |
