Hallo Per,
> But you got reading to work?
I converted a D64 image into a G64 one and send that data to PortA2. But I
got read errors all the time.
> What didn't work when writing?
I got rubbish all the time. I tested this by shorting the Motor-On signal so
the disk kept spinning continiously. My first try was reading port A as soon
the SYNC signal was detected but.... rubbish. Then I put a 74ALS575 between
the LPT port and the 6522 that would latch the received data and still
rubbish.
Maybe I did something wrong, I don't know. But knowing much more of the
system now, and having the ability to create my own 'ROMs' which simplifies
testing, I'm thinking about reviving this project.
