|AT&T PC 7300|
|by Bill Degnan - 01/02/2010 10:17|
This AT&T PC 7300 was donated for study. The AT&T PC 7300 UNIX Computer from 1985. Serial Number 370429020 000139
So far I have tested the power and the memory, all OK. System originally booted up, but I did not have any login info so I decided to format the drive and re-install the OS from disks. There is a minimal OS 3.5.1 loaded for the moment. Doing research to determine next best action.

The ST-251 does not appear on the options when initializing a hard drive from the diagnostic menu. I chose "other drive" from the option. The ST-251 has the following specs:
If you divide 4920 by 820 you get 6, which is the tracks per cylinder ratio. used 17 sectors/track. You need this number to correctly format the drive. [edited].
Anyway, after the format and surface scan completed (took over an hour), I re-installed UNIX 3.5.1 successfully and fully. Next I plan to install software and configure to my taste.
