The PC hardware is so crude and simple that even with
MY soldering skills,
it is possible to do mods such as for single density. The Mac hardware is
much more integrated, and is full of surface mout chips, etc. that I'm not
skilled enough to work with.
Depends on the PC and the Mac :-). Modern PCs seem to be stuffed full of
SMD (and worse still BGA) chips. The disk controller is probably part of
some large ASIC on the motherboard.
Conversetly, the Mac+ has no SMD chips other than in the floppy drive AFAIK.
