Hp9133 hardware problem

[Maximilian Hohmann]

Hi Dave,

thanks for the quick reply! I think it must be another fault than the sticking head, because the drive can be heard turning and making other sounds more or less typical for hard disks. It also manages to pass the "Winchester speed" and "Winchester seek" self tests. (But not "Winchester write verify" and "Winch. verify" - passing the "write" test would not be important as we only need to read some files right now).

The Data Acq ROM, according to a manual I found online, can only access the HP 9114 Disc Drive (which is floppy disc only other than the 9133 which has one floppy and one hard disk). Anyway, I think that it will be near impossible to find.

Right now I am bidding on GPIB/IEEE488-cards on eBay and if successful will try accessing the disk through one of these (myself I turned to Macintosh right after the Hp150 but our son has a PC).

Regards
Max
