ZX81 (stable?) Video Out
Posted: Tue Jun 30, 2020 7:13 pm
Hi there guys,
recently Ive set my mind on getting a ZX81 and attaching it to a more modern display (e.g. non 1084 crt display).
However, I notice that my digital devices do not detect a stable signal output, and thus the display remains either a) black, because the modern hardware cant make sense of the unstable input or b) I have a display but it constantly `rolls' over the display vertically.
I am new to this forum, but am wondering if you guys have encountered (and hopefully resolved) this issue.
I have seen the FPGA ULA replacement and ZXVid composite mod; would either of these solve the problem I have? Are there alternatives to get a stable out?
Kind regards,
Wietze
