Hi,
I have an old keyboard chip for a Sol-20 computer. I want to make a simple little circuit with a PICAXE chip to take the standard USB keyboard and translate the keys to drive the Sol-20 computer keyboard chip. Essentially, 2022 USB to 1975 7-bit ASCII out.
I don't know how to read the USB signals from the modern regular USA 102-Key keyboards.
Once I know how to input the USB keyboard key strings, I'm fairly sure I can create a translation table to drive the Sol-20 keyboard chip for the 96 to 128 characters I need.
