A20B-2902-0341 | 4MB FROM with 256K SRAM

Fanuc A20B-2902-0341 memory board. Combining between the two different memory systems; allowing the Fanuc Series 16-C control to compute faster. The FROM is 4MB and the SRAM is 256KB; while on the lower end of capacity even for Fanuc it was still a very novel approach combining two memory types into one PCB across one backplane port.

Though an early version of the combined memory cards this has become popular with later control systems. Please note because this board is your FROM for the Fanuc control. If its needs replaced you will require a full backup beyond SRAM, PMC to include NCbasic files as they are stored on the FROM.
