PS/2 Encoder interfaces industry standard PS/2 PC-compatible keyboards to devices requiring TTL-level RS232 or parallel data signaling. All ASCII key sequences are decoded, as well as common keyboard sequences like "CTRL-ALT-DEL". To provide maximum flexibility for various uses while retaining ease of operation, the unit's configuration can be modified in-circuit using the PS/2 keyboard itself. Features include:
PS/2 Encoder consists of an Atmel ATMEGA88 AVR microcontroller and associated connectors. The unit can be ordered as a base PCB, a minimal parts kit, a full parts kit, or a completed unit.
The PCB features include:
Construction details and configuration settings are available on the product information page.

I'm in the process of building a couple of Z-80 computers and needed a keyboard input. I was dreading having to take a PC keyboard apart and trace out the key switches to get ASCII out of it. This does parallel AND serial simultaneously and is highly configurable. Thank you for saving many hours of my life!

Very easy to interface with, and easy to use. The instructions for the unit use can be found on an associated product information blog, but it would have been a bit easier if there was a hard copy. It was nice to have the schematics and source code available on their website if I ever wanted to add extra features I could reprogram the ATMEGA. Also, the GNU licence is a plus.
