One of the not-much-larger-than-a-postage-stamp SD card disk drive
emulators for the C64 does exactly that; it makes the same comfortingly
familiar nasty sounds that a 'real' 15xx CBM drive would make.

I take a different view, at least with my Commodore 64 and Amiga 3000. Over
the years, I've souped both up quite a bit. I just wish I could afford CPU
accelerators for them!

Are there in fact CPU accelerators for the C64?
I was never much of a Commie, though I do have a C64 and a 1541 in
the closet that I've not yet done anything with. Back when it seemed
someone was either an "Atari person" or a "Commodore person", in the
early 1980s, I was in the Atari camp with an '800. My best friend
had a C64 though, and was always happy to show off its capabilities.
Good stuff.

Yes. :-) I had an Amiga 1000 back in 1992 or so, and while it
wasn't my primary system (of use or interest) as I was all UNIX by
then, I always thought it was an amazing system. I sold it, and as
with most everything I've gotten rid of, I regret that decision. My
boss has a few 1000s and he has promised to put together a nice one
for me, and I'm looking forward to giving it a home. What amazingly
powerful systems!

There is also the TurboMaster (4MHz), and
the TurboProcess (4MHz) as
well as the Flash8 (8MHz)
How is it implemented?
All run on the same principle. Use the BA signal on the
cartridge port
to tristate the internal CPU (6510/8502). Implement an entire 65C816S
or 65C02 SBC on the cartridge, minus any IO. Run the internal SBC at
4,8,20MHz, with some buffering between the SBC bus and the C64 bus.
Implement either clock stretching or wait states to slow down the
external CPU when it needs to communicate with internal RAM or IO.
Tada.

The 1541 Ultimate has audio out jack for that authentic drive head
banging experience!
I have one, but yet to investigate its capabilities.
