Disk/Tape Controller Modules Supported
The following VMEbus disk/tape controller modules are supported by 177Bug. The default address for each controller type is First Address. The controller can be addressed by First CLUN during:
❏Command BH
❏Command BO
❏Command IOP
❏TRAP #15 calls .DSKRD or .DSKWR
Note that if another controller of the same type is used, 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.
