Hi Paul,
What's the line counter in your ZX80 replica? The counter of mine is 74LS393.
I have attached the slow mode schematic and I checked and re-checked several times.

SLOW MODE issue
I have built a similar replica of ZX80 w/ slow mode. It’s working fine but has only one issue when working in slow mode.
Both inverse and graphic caracteres are missing a line over the caracter as you can see in the Picture.
Has anyone ever seen this problem?
