Another mega STE motherboard i have recently been working on
Just 1 small issue i can't seen to solve is it will not detect or see HD 1.44MB Disks
All ok with 720K disks, it opens, formats and writes but not HD disks, nothing, the drive just searches and searches as if there was no disk in the drive
It has TOS 2.06 / AJAX floppy IC fitted / dip switch 7 in ON / GAL U407 tested ok
Is there anything else i can check?
