Hi #Retrocomputing Fedi! I'm teaching a #computing #history course next semester; as part of the course, we want to showcase some period hardware from the "first four generations" of computers (vacuum tube, discrete transistor, SSI/MSI logic, LSI/VLSI microprocessors).

In this vein, I am hoping to acquire one or more digital flip-flop modules in both vacuum tube (e.g., #IBM TR-x) and discrete transistor (e.g., #DEC flip-chip) technologies. If would like to sell or donate one, please contact me!
