![]() ![]() This situation was my inspiration for the adapter shown here. If, like me, you are into older machines and system boards from that era, you were stuck either spending a lot of money or trying to adapt a no-name adapter board and try to make it work. There are PS/2 to serial or parallel adapters available on eBay, but they often don't have a strobe signal, and no way to adjust the timing to use with older equipment. Occasionally you will see one on eBay, but usually for an exorbitant price. Keyboards with a 7 or 8 bit parallel ASCII output were available from several sources, but are no longer manufactured. It was very common during this time for a hobbyist to 'roll their own' system with parts from different sources. Older machines and single-board computers, particularly ones from the mid-to-late '70s through the very early '80s often used a parallel keyboard input.
