Serial Keyboards on eBay...

I recently restored a system that required a TTL serial keyboard. I initially "hacked" a setup using a VT520 (RS-232) with a "SchmartBoard" RS-232 to TTL converter. Then I found several Keytronic RS-232 serial keyboards on eBay from a single vendor. After reading the specs, I found the keyboard supports both RS-422 and RS-423 by jumper settings. The default setting is RS-422 - which means that one can use "one-side" of the differential output as TTL serial. It also defaults to 300BPS - which is what I needed. (The specs say it can do 9600BPS as well). For those who care, the keyboard is "driven" by an 8048 8-bit microcontroller. I bought four of these keyboards in a previous auction from the same vendor and they are in excellent condition. He now has them listed again as item #300237350802. Starting bid is $9.95...
