Commodore PET disk drive power-up error codes

[Dave Dunfield]

Hi Guys,

Does anyone have information on error-codes that are flashed by PET disk drives
after power-up diagnostics fail.

I have a drive set which after powerup, enters into a state where it flashes the
POWER LED alternating with both drive LEDs (together) - It repeats this flash
cycle exactly 6 times, then pauses, then another 6 ... forever.

I assume it's a diagnostic failure - Can anyone tell me what it means?

Regards,
Dave
