I have version supplied from exp.port, but I have a "strong" PC PSU. But, it's terrible, when the heads are moving, the C64 screen blinks... The save error isn't caused by a supply decrease, other experiments return messages "name to long" (not too long...) or "disk is write protected". But there is a little progress. Disassembling revelead different offsets in tools and ROM. E.g. tools calls: JSR $89DB but correct (and working) according to ROM is: JSR $89D9 LHS Spiro Trikaliotis wrote: > * On Sun, Apr 15, 2018 at 12:37:37PM +0200 Tomas Vondracek wrote: > >> Anyone have the manual or experience with this drive?
