vic-20: disk drives seem to be good for ONE operation, then it results in "no drive connected" error #244

jinchoung commented 9 months ago

so i can attach a disk and load something but after that, i cannot save again because an error prevents recognition of the attached disk. repeating the attach disk or detaching and re-attaching does not fix. also, i can write a little program and save it ONCE. and then after that, the disk/drive has a disconnection error that cannot be fixed except with a power off. i believe even a hard reset will not allow a disk to be attached again.

also, flushing the disk works (thanks!) but it results in a strange corruption where anything i type after that is stuck in weird graphics which actually don't seem to conform to the proper petscii characters. and this is without holding down shift or the C= key. this continues until i do a soft reset but then i believe the disk is rendered unusable again per above paragraph.
