Build a S-100 Debug Board

I finally got a chance to write up the new S-100 debug board I've put together. It incorporates the most useful functions from my original board (first used to get my first S-100 card up and running...the Cromemco ZPU!), including the HALT LED and a 4-character ASCII LED display with several address decoding options. The writeup can be found here: http://www.glitchwrks.com/vintage/s100/debugboard.html

Here's a picture of the complete board:


It should be getting a workout with the S-100 6502 board, when it arrives!

If anyone has an IO-2 board they'd like to part with, please let me know. I'd like a second to build as a 1702A PROM board. It doesn't matter what condition it's in!
