VAX 6000

The VAX 6000 family supports Digital's VMS and ULTRIX operating systems.

The bottom of the cabinet contained a provision for an optional battery backup unit and two RA90 or RA92 hard disk drives.

The KA64A contained a 35.71 MHz (28 ns cycle time) Rigel chip set with an external 128 KB B-cache (L2 cache).

The module also contained a REXMI chip set, whose purpose was to interface the Rigel chip set's DAL (data and address line) bus to the XCI ASIC, the user side of the XMI corner interface.

The XCA and XCP were ASICs developed using a standard-cell methodology and fabricated in Digital's CMOS-2 process.

It contained 0.25 million transistors on a 0.595 by 0.586 inch die packaged in a custom 339-pin ceramic pin grid array (CPGA).
