A friend and I have designed a front panel controller
that connects to a
PC port and allows you to have up to 128 outputs (LEDs, lamps, etc.) and
64 inputs (switches, etc.) It is intended for use in functional
blinkenlights replicas (like the PDP-1 replcia I'm building). It connects
to a PC parallel port and is driven through software. It can be updated
hundreds of times a second, which for all intents and purposes will seem
continuous. We're going to write simple software drivers to control the
board. It's simple enough to be integrated into just about any PC-based
emulator and is designed to be scalable (up or down).
How does this one compare to the "blinkenlight console" project Henk Gooijen
is doing?
