Product Description

This is a Giddings & Lewis 501-03865-01 processor module. The board silkscreen reads Processor Module, 501-03865-01, and a second number that starts 502- and ends 3061-51, which is partly covered by a label. A label near the bottom edge reads 503-15651 and its last digits are not readable. The S/N field is partly covered by a label and is not readable, so no serial number is listed. The Giddings & Lewis logo is on the board.

The board is populated with ICs, including a Motorola MC2661PB and an NEC D8259AC-2, along with resistor networks, jumpers, test points and four labeled EPROMs. The silkscreen marks Conn A Serial Port and Conn B Expansion Bus. Gold edge connectors run along the left, right and bottom sides, and ejector handles are at the top and bottom corners. The photos show the board in an anti-static bag.

Sold as surplus, untested. This unit has not been powered on or tested by MRO Exchange, and the processor, memory and connectors have not been verified.
