With the SCSI connector on the right, power's top-left, middle-left is the ST506 control connector, then J2 and J3 St506 data connectors bottom-left? Lots of analogue circuitry toward the top of the board in the middle, ROM bottom-right, and 3 40-pin ICs toward the bottom of the board in the middle. These boards don't support Identify - which is what makes plugging them into modern hardware in order to archive data a real pain. Modern host adapter firmware and software drivers tend to expect to be able to identify the device before they'll talk to it properly :( If just have a J4 connector (not present on all boards) near the ST506 data connectors, don't plug anything into it - it's a factory test socket, not any kind of drive data... That Xebec's actually SASI not SCSI incidentally... if the Torch SCSI board is operating in some kind of SASI mode then a modern SCSI drive might not be too happy talking to it. SCSI command class 0, opcode 0x0C is 'initialise drive characteristics' - the host needs to send this to the board with params in order that the board can address the drive(s) properly. (the S1410 manual's on the floor here from where I've been bodging a homebrew SASI controller onto a PC in order to drive one of the boards :) cheers Jules
