Evolutionary design of the legendary ASCII Keyboard Tester. It can now eavesdrop on the signals generated by a keyboard and transmitted to the vintage computer, without interfering its normal operation. Of course it still supports familiar standalone usage, so a (self-made) keyboard can be tested in isolation. All bits are annotated to ease conversion and understanding of hexadecimal and decimal number systems.

Use the DIP-swich to turn off the 8th bit or activate adapter mode. The latter is to use an Apple 2 keyboard with an Apple-1 computer. All keyboard connector pins are labeled to make it easy to connect ASCII keyboards that go with other computers, like the Sol-20 of Processor Technology.

Unsoldered kit comes with the pcb, all parts, schematics, bill of materials and manual. See the Documentation for details.
