Fast Serial Board

Thanks to Derek Stewart, I’ve been able to add the schematics for Terry Harman’s fast serial board for QL, allowing communication speeds up to 115,200 baud.

Plotter files included for printed circuit board, GAL 20v8 prog logic etc.

Three files available to download in all – go to the hardware documents page on my website, scroll down to the ‘Fast Serial Board’ section:
