Able Computer was a company based in Irvine, California which made a variety of device controllers and similar devices (e.g. caches) for PDP-11s and other machines which used the UNIBUS or QBUS.
The controllers were usually program-compatible to existing DEC products, but more cost-effective; the other boards offered performance and capability enhancemens that DEC themselves did not offer.
The following table gives the part numbers and sizes of Able product, to aid in identification of unknown boards:
| Product | Part Number | Size | Bus or Machine |
|---|---|---|---|
| DH/DM | 10100 | hex | UNIBUS |
| VMZ/32 | 10185 | hex | UNIBUS |
| REBUS | 10014 | double dual | UNIBUS |
| Dual I/O | 10039 | quad | UNIBUS |
| INTERLINK | 10064 | hex* | UNIBUS |
| BUSLINK | 10062 | quad | QBUS |
| DMAX/16 | 10048 | double hex | UNIBUS |
| CACHE/434-440 | 10031 | double dual | PDP-11/34, PDP-11/40 |
| SCAT/45 | 10017 (control) 10025 (data) |
hex (control), hex (data) | PDP-11/45, etc |
| QUADRASYNC/E | 10028 | hex* | UNIBUS |
| QUADRACALL | 10045 | quad | UNIBUS |
| DZ/16 | 10090 | hex | UNIBUS |
| VaxDZ | 10140 | hex | UNIBUS |
| UNIMAP | 10143 | quad* | QBUS (UNIBUS input) |
| QUADRASYNC/B-C | 10015 (-B) 10022 (-C) |
quad | UNIBUS |
| DV/16 | hex | UNIBUS | |
| CACHE/45 | quad + double dual | PDP-11/45, etc | |
| QNIVERTER | quad | QBUS (UNIBUS input) | |
| ENABLE | hex* (main board), quad (optional cache) | MUD (UNIBUS input) | |
| Q/DH | quad | QBUS | |
| QNIMAP | double dual | QBUS |
* indicates a non-rectangular board
The notation "PDP-11/45, etc" means it also applies to the -11/50 and -11/55 (machines which are physically identical to the -11/45, with different main memory configurations).
In some documentation, the INTERLINK was also named the 'Interlink/UNI', and the BUSLINK the 'BUSLINK/LSI' .
