No need to do that, I have a real 1540 drive with that chip now. Last
time I tried to read the error channel it didn't work (i.e. crashed
after a few characters), but that was because I used a C64 and was too
lazy to look up the screen disable POKE. This is on my list of to-do
things, right after aligning my SFD1001. Somehow I finally have all
parts I need for that: analog alignment disks for 100tpi drives, a CBM
to run the alignment software, the software itself, and a 20MHz dual
channel oscilloscope :-) If that works, you can all send me your 100tpi
double sided drives to align them.
