> A very quick Google search brought me this: > http://www.bitsavers.org/pdf/ansi/X3T9/X3T9.3_185_RevE_SASI_Apr82.pdf It does indeed seem to have the more or less the same structure as its successor SCSI, including the variable length commands. Looking at page 32 (37 in the PDF), it does have six-byte group 0 comands, 10-byte group 1 commands and 12-byte group 5 commands. I don't have my SCSI quicksheet available, but that's quite like SCSI. Wikipedia does have documentation for many of the standard SCSI commands - http://en.wikipedia.org/wiki/SCSI_command For SCSI, the range of commands differ depending on the type of device you are targetting, so you first need to ask the device about what it is (12 INQUIRY), and then target your commands accordingly. It doesn't seem like SASI had that. (In my previous job, with tape streamer libraries, I did work with SCSI commands, both on the sending and receiving side. Mostly that was tunneled over a serial "ADI" interface, used for communication between the library and the tape streamer(s). The command interface was SCSI, but the link was a fairly simple serial cable). -- \\// Peter - http://www.softwolves.pp.se/ Message was sent through the cbm-hackers mailing listReceived on 2011-01-27 10:00:11
