Product Description

This is a Giddings & Lewis 501-03852-00 / 502-03055-00 servo board. The board is marked SERVO BOARD, with two part numbers printed along the top edge that are partly worn and read only in part (3852-00 and 02-03055-00). It carries a Giddings & Lewis Electronics logo and the silkscreen date RE 4/86. The S/N field printed at the bottom right is blank in the photo, so no serial number is listed.

The board is a green circuit board with gold edge connector fingers, a D/A converter module marked MNDAC80-CBI-V, a 16.384 MHz crystal, and many TTL logic chips and resistors. Servo channel markings, test points TP3 and TP9, and cream-colored extractor handles are visible. A thin white string hangs from the lower right corner. The board shows some dust and light wear.

Sold as surplus, untested. This unit has not been powered on or tested by MRO Exchange, and the board and its components have not been verified.
