HP 1AA1-6003 (48-pin ceramic gold trace LCC; pictured in thumbnail)
HP 1AA6-6004 (48-pin ceramic grey trace LCC)


The 1AA1-6003 and 1AA1-6004 are variants of Hewlett-Packard's silicon-on-sapphire MC2 processor, originally designed for the ill-fated HP 300 Amigo microcomputer and later used to greater success in the HP 3000 Series 33 minicomputer. The original HP 300 chipset consists of the 1AB2-6003 processor control unit (PCU), 1AB3-6003 register, address, skip and special (RASS), and the 1AB4-6003 register, arithmetic and logic unit (RALU).

While the 1AA1-6003 is currently unidentified, the 1AA1-6004 is known to be a MC2 processor modified as a HP-IB controller.
