DDisk/Tape Controller Data
Disk/Tape Controller Modules Supported
The 172Bug firmware supports the following VMEbus disk/tape
controller modules.
The default address for each controller type is First Address. The controller
can be addressed by First CLUN during execution of the BH, BO, or IOP
commands, or during execution of the TRAP #15 calls .DSKRD or
.DSKWR. If you use another controller of the same type, the second one
must have its address changed by its onboard jumpers and/or switches, so
that it matches Second Address and can be called up by Second CLUN.
