Disk ][ Refurb



I am the proud owner of drive #582 ( and # 972, as well). Not to
gloat, but that's pretty cool.

Anyway, #972 works fine, probably because it was Drive 2 for it's
entire life. I have the other disk 2 drive disassembled.
First question:
Which one of those pots on the analog board is used for the speed
control?

Second:
Is there any need for head alignment? I have read that these drives
are pretty brainless and that knocking sound on boot is the controller
putting the head in the right place (there is no mechanism in these
drives to determine absolute head position.

Third:
What do I clean the head with?

Fourth:
Does any part of the drive enjoy lubrication (lots of squeaks)
