Product Description

This is a Giddings & Lewis 501-03854-01 communication board. The silkscreen reads COMMUNICATION BD RN5-2, 501-03854-01, and 502-03063-01, with RA 12/84 and 4.912MHZ near the bottom edge. The G&L Electronics logo with AMCA International is printed on the board. The silkscreen also reads Board Test, I/O Test, Digital I/O Conn A Port, Serial Port w/FIFO Conn B, and Serial Port Conn C. The serial label at the bottom right carries barcode A32919, and the S/N label is partly cut off, so the serial number is not stated here.

The board is a double-sided through-hole board with gold edge connectors on two sides, labeled P1 and P2, two plastic ejector handles, and rows of socketed and soldered chips. The board shows dust and light handling wear.

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