Many third party peripheral devices have one of these drives hidden under the cover. Other drives should work, however command set differences may result in driver problems. Reports of what does work and especially what doesn't work are appreciated. 2) ST506/ST412 drives are fairly generic these days. The one restriction to keep in mind is that the A2090 does not support relatively exotic drives having more than 8 heads. Check drive specifications to avoid embarrassment in this regard. 3) The A2090 hardware and firmware is capable of supporting buffered SCSI tape and other peripheral devices, however the current driver software is oriented towards disk devices. Hopefully this situation will be improved in the future. -- George Robbins - now working for, uucp: {uunet|ihnp4|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@uunet.uu.net Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)
