Ahhh the 1541/1571...

The things we didn't do on those drives to speed up loading...

They both have an onboard 6502 and 2Kb RAM, so we used to transfer a *fast
loader* into the onboard ram and then take advantage of the ACK line on the
serial port, so we essentially had 2 bit transfer... That coupled with some
funky interleave stuff gave a pretty fast load on the c64....

I have JiffyDOS in my C64 and 1541 Drive which speeds it up quite a bit. 
There are also various fastload cartridges that add similar functionality. 
Compute! magazine even had a free Fastload program you could type in, save
to disk and run at first boot to speed up all future disk operations.

JiffyDOS is also available for the C128 and 1571 drive.

The commodore serial bus was hell, it was designed for a hardware handshake
But due to bugs in the hardware it was reverted at the latest minute to a
software bit banging

I think that one of the latest disk drive made by commodore uses the
original hardware scheme planned (but only when connected to a C128).

I do recall the Commodore disk drive was a serial device slower than the 
CoCO cassette port or something like that. My advanced C64 friends had some 
kind of plug in cartridge to accelerate it, but others did not. I remember 
seeing this on a C64 game once:

PLEASE WAIT 3.5 MINUTES WHILE THE GAME LOADS

How far we have come :)
