Pulse Counter Assembly Burroughs C-2506-4 Four Digit Nixie Memory Decoder TTL Logic

This is an unused, factory fresh, genuine Burroughs C-2506-4 four digit B5750S Nixie tube type counter with memory and decoder driver circuit card assembly. It uses standard TTL (Transistor Transistor Logic) input logic signal. The high quality, fully loaded, socketed, factory built pc card comes with gold plated 30 pin edge connector. The unit requires 5 Volt DC (Direct Current) and 200 Volt DC for its operation. It was made by the now defunct Burroughs Corporation Electronic Components Division (ECD Plainfield NJ) around 1968-1970. This unit is unused and in excellent working condition. This card is a complete four digit pulse counter assembly and it makes a good evaluation circuit. Only a time base circuit reqired to make it a classy frequency counter or a DMM. Typical input toggle rate is 25 MHz. Excellent as a replacement, or for new projects. This is a real hard to find vintage collector's choice item. Only one available.
