ZX SEMI A liberal adaptation of SEMI OCR.
SEMI is an OCR font designed by SEMI.ORG for use in character recognition on printed circuit boards in 2006.
I made this liberal bitmap-only 8x8 adaptation after somebody requested it on one of the Spectrum forums. It takes more than a few cues from OCR-A but goes off in its own direction.
The actual font is upper-case only, so I've had to imagine what the lower-case would be like in-order to provide a full usable set.
This font works surprisingly well for most use cases.
