Could some kind soul explain to me how the A590 (or should that be A509 ?) hard disk adaptor for the A500 works ? It seems to be capable of supporting both XT and SCSI drives, judging by the markings on the PCB. Does this mean that I could buy one and replace the baby XT disk with a decent sized SCSI disk ? Do I need to change any straps on the PCB ? If not, how does the board know which type of drive is attached ? Thanks in advance ....

Ther was no straps or anything I should move. So I believe you can just switch original XT-drive to SCSI drive and go. Only switch with these things is on front, and it says which interface (SCSI or XT) controls disk activity led. Drive information is written on disk by format, and driver picks it from there, interface itself doesn't care. -- pl@tut.fi !

I have an A590 that is running both the standard 20 meg XT drive and a Quantum 40s drive. Just plug the SCSI drive in (power and SCSI cable), config the drive with HDToolBox and voila`. >Thanks in advance .... > >Andy Michael > ----------------------------------------------------------------------- | Brian Jackson Software Engineer @ Commodore-Amiga Inc.
