September 1998. I'm looking for this old unit functioning to purchase it, actually I need the PACK or FIXED PLATE also called HDA, the interface of this unit is SMD and there may be manufacturers that emulate SMD with SCSI disk, (an alternative of this type as long as it is transparent and that doesn't require modifications in hardware or software would do). BRAND : Ampex MODEL : 932 (DFR-932) P/N : 3311637-01 DISC TYPE : Winchester ( 1 FIXED PLATE, 1 REMOVABLE PLATE TYPE BASF CARTRIDGE) I/O INTERFACE TYPE: SMD/CMD INTERNAL PROCESSOR : INTEL 8085A - 5 Mhz.
