I found recently an article on an old 1983 Italian magazine (Elettronica 2000) describing an Hi-Res board for the ZX81. http://speccybits.altervista.org/scansioni/e2000_46.rar This article describes a board (including its layout) which is most probably a QS HI-RES clone (the text refers to a resolut...
