Using an IBM PCjr wireless keyboard

And also because the PCJr keyboard will withstand significant levels of abuse. It is not waterproof nor submersible (in stock form), but it can survive most splashes and spills. If you want to build hardware to use it on a PC, you could simply use a Jr, and connect THAT to the PC. Old, used, PCJr's are the cheapest source for the hardware needed to interface a Jr keyboard to anything else. In terms of the "line of sight" issue,... fresh batteries are essential. But connecting a cord (RJ11, but does it need a twist?) turns the Jr keyboard into a corded keyboard. Many years ago, during the great "how many buttons should a mouse have?" (HMBSAMH) debate, we used velcro to attach a Jr keyboard on top of a mouse. -- Grumpy Ol' Fred cisin(a)xenosoft.com
