Probably a better solution would be to build the whole controller with modern hardware and
simply emulate the key pieces in an fpga. That would ensure a high degree of compatibility
and could even use the 1541's native rom image.

But it reminded me of another old related
question,could you today, build a
brand new 1541 with current parts? I dont mean emulated like the SD drives or
whatnot,I mean a real, functioning, exact 1541. Is it still possible to buy a
brand new 6502, 6520, IC ?(I did a quick search, but my google-fu sucks atm)
Well, I doubt anybody is making 5.25" drive mechanisms any more, especially
nothing as cheap and nasty as those clunkers Commodore used, so that's your
first hurdle. For authenticity, you'd also need to machine yourself a fugly
case that's too big to fit anywhere convenient on the desk.
Which brings you to NOS parts, at which point you shouldn't have too much
difficulty sourcing the 6502 etc -- except they may well have been pulled out
of a 1541 in the first place!
