I decided it would be nice to add a parallel port to my 1571 (will be the socketed kind) and started taking it apart. First I noticed the mainboard looking like it has had some patches applied (a bunch of cables soldered between some of the chips etc). I then started looking for a 6526 chip, but there were none.
After removing the mechanism I got a better look at the mainboard and it said 1570... Also, the chip sitting where the 6526 is supposed to be is a 8520R3, which seems to be an Amiga CIA chip!?
I got it second hand, so I don't know its story, but atleast the case says 1571 and it works just fine with my C128 (and with opencbm) :)
Is it safe to assume the 8520R3 is similar enough to a 6526 to work with a parallel cable?
Parallel cable now installed and working. :)

What program are you using with it? Do you have photos of the installation?
