Hallo Richard, > Are these incompatibilities the same as the C64 / C64C ones?

A friend of mine has one. I cannot remember details but the 6522s and 6526 of the 1571 have been put in one single VLSI chip. But certain not needed registers have been left away. I have no experience but he showed me some copy PRGs which worked fine on the C128D, my C128/1571 combination but not on the C128DCR. > (No I am not going to hack into my perfectly good plastic C128D, > thankyouverymuch) I have two but from one the case and drive are bad. This one I use for experiments with the 65816. W/O drive I have a lot of space :) Groetjes, Ruud - This message was sent through the cbm-hackers mailing list.
