This was perhaps the most unique S-100
board put out by Wameco. It was meant to replace the simple LED
driven IMSAI board. The display of data and address lines were in HEX displays.
It could do all the things the IMSAI or Altair front panel switches could
do but with a nicer display.
I found mine did not work well at or above 4MHz in a Z80 system however.
The manual for this board can be obtained
here.
