I recently acquired the keyboard and computer for the AT&T 6300 from eBay. It pairs nicely with the old AT&T terminal monitor I have, which is in the same model family as the monitor that shipped with the system.
Of the many issues I'm sorting out, one is that the ST-225 HD doesn't boot. Not that I'm surprised. I've never really tried to troubleshoot one of these drives, but there's definitely life in it - I can hear the stepper motor seeking on startup. But it repeatedly clunks (like the head is seeking to track zero) and the computer doesn't see the HD. You can hear that activity in the Youtube video I've linked below.
With an MFM drive in this state, is seems like there's a chance to repair it. Before I get too far down that path, I wondered if anyone has any tips or thoughts on some basic diagnostics?
