Hi-Res once and for all, PLEASE

Post by albertusj »

Can someone please explain to me in technical terms how the Hi-Res on a ZX81 work? I have tried modifying a homemade pack I build using a 7400 and 62256 from a design by Grant Searle to no avail.

Please see my post:

The thread had gone stale so I'm not getting any replies.
