It the machine crashes, then it will not be able to respond to an abort key press.
Can you post a link to some disk images that make it crash? I can code around the corrupt/unexpected data so it does not crash.
it’s a folder called “SP1200 Collection” with 99 files and the first two work and the rest gets stuck.
Got this from the net somewhere and happy to share.
My original self-saved hfe ones from my SP1200 work fine, though.
