Re: How to lobotomize unidisk 3.5 so it won't go boink and will work w/copy II+ bit copy?

[buggie@ben02.unm.edu (stephen e buggie)]

DONT LOBOTOMIZE THAT UNIDISK 3.5!   I worked hard to restore two of them.
The restorations worked, although I had to fit the plastic cases together
with duct tape.  I installed a 40-pin socket for the 6502, and that meant
that the plastic shells would not fit exactly.  Soldering a 40 pin chip
into its board seems like computer blasphemy.

If you can use a grey Apple 3.5 drive, I'd swap one of those in perfect
condition to receive the Unidisk 3.5 in as-is condition, even if
non-working.
