Apparently a solution almost exist to repair the broken 9060/9090 a board: SCSI2SD permit to connect a board converting SCSI to a sdcard http://www.codesrc.com the commodore is not SCSI but SASI some differences exists: - no termpower on SASI (it is possible to build a custom cable with the termpower wire removed) - on the 9060/9090 the ATN and Parity Lines are not connected - the 9060/9090 is using vendor specific commands. everything could probably work with a custom cable + some modification in the firmware of the board. this board has a support for a replacement of SCSI drives in apples. he could eventually add the support for SASI commodore 9060/9090 if someone is interested. but some help would me needed on my side I have - schematics take from zimmers. - several sasi document from shugart and from sasi to mfm converter - I have disassembled and commented the firmware using sasi commands... - I have a list of the command used by this firmware I'm stuck on: - the datasheet for the CMI SASI <-> MFM (no way to find it) - the mapping of the error codes between SASI errors codes <--> commdore error codes I dont have any way to test (no 9060/9090) I think his solution could be interesting if adapted to the commodore. -- didier Message was sent through the cbm-hackers mailing listReceived on 2014-01-28 14:02:12
