Product Description

This is a Giddings & Lewis 501-03852-00 / 502-03055-00 servo board. The board is marked SERVO BOARD, with the number 502-03055-00 printed along the top edge and part of a second number ending in 3852-0 partly cut off in the photo. It carries a Giddings & Lewis Electronics logo and the silkscreen date RC8/84. The part number labels on the board are only partly visible, so the full 501-03852-00 number is not confirmed from the photo. A barcode label near the bottom edge reads A16860, but the label is cut off 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 DAC80Z-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 white string is tied to the upper right corner.

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.
