80-pin to 68-pin / 50-pin adapter (allows you to use ANY 80 pin SCA-2 (hot-swappable / hot-pluggable) hard drive in PCs with standard 68pin or 50pin internal SCSI controllers).
It is fully compatible with the following SCSI standards including LVD: U160, U80 and SE modes: Wide, Fast-Wide, Ultra 2, Ultra 2 Wide (U2W).

about 1996. It is limited to Narrow/Fast SCSI II which has a limit of just 10MB/s.
Examples of 50pin SCSI are often found in Apple SE, SE30; II, IIx, IIci, IIsi,
