A maximum configuration of the Burroughs B5500 allows for:
|
|
|
|
* Two central processing units.
|
|
* Eight independent memory modules (each 4,096 48-bit words).
|
|
* Four floating input/output channels.
|
|
* Sixteen magnetic tape drives.
|
|
* Two billion characters (2GB) of on-line disk storage.
|
|
* Two line printers.
|
|
* Two card readers.
|
|

In October-1970, Burroughs renamed the B5500 to B5700 as part of the introduction of the 700-series family (that inluded the B6700 and B7700) and added new capabilities:
|
|
|
|
* Support for B6700 DataComm for communications
|
|
* Support for adding B6700 memory modules as auxiliary memory.
|
|
|
|
B5700 AuxMem was implemented primarily as an overlay mechanism, and the extra memory appeared as the deprecated B5000-era drum storage devices. These appear as devices DRA and DRB in the MCP. Use of the drum device interface limited the auxiliary memory to 32kWords each, for a total of 64kWords of AuxMem.
