I recall that the "off by one" cable mistake required replacement
of a socketed chip, a ULN2003-type driver? A less than one dollar

I know we like to argue about component level debugging, but there's
only a small number of chips on the boards involved, all socketed.
Heck, except for the PROM you could replace every single chip
for circa $12.00.

Neither did I, for much the same reasons. And I
had to repair quite a
few that went out of alignment, and some that had released the magic
smoke when someone plugged the drives in "off by one" after they
disconnected them to move the machine.
That was a problem I also saw with the drives. Several of my friends
had Apple IIs (I had a 32K PET 2001-N), and ISTR more than one person
did that. Not cheap. My memory is that at the time, the bare drives
were $600 new, so even if one just replaces boards, it's not
inexpensive in that environment.
