I use(d) simple 8-bit interface http://c64.uz.ua/misc/inter.gif. At the C= side it needs
only 8-bit port and 2 handshake lines (can be also hardware handshaked
by CIA). PC side needs parallel port lines: 9 outputs , 4 inputs (with handshake
lines ofcourse). 3 TTL chips used for decoupling the handshake lines
from C64 synchronous to PC asynchronous protocol. So no matter what MHz
you have at the both sides. The lines at the interconnecting cable are
unidirectional, so buffering shoulnd'nt be problem (two extra TTL logic).
The transfer speed is around 50Kbyte/s at 1MHz C64.

I wrote simple 1541 disk copier (to PC yet), so program can transfer whole 35
tracks to PC about 23 seconds. Nothing else developed except simple
Load/Save routine.
Marko also wrote a prlink implementation of it.
