General Description This is an 8039 microprocessor-based logic/control board for operating B-G Instruments' model PM1416 print mechanism. It's user functions are determined by the program contained in an onboard EPROM (27C64.) The standard program for the CB-420 supports parallel and limited serial ASCII data input, printing in the X and Y directions and versatile graphic plotting. Custom programs may also take advantage of an auxiliary keypad input on this board. For detailed information on these features, refer to the "Standard DataPlot Commands" datasheet or custom program specification. Please note that this board does not support all the features that are available on the CB1000 series control board.
