Noisy 2A displaymy 2A gives a fairly good display until it has to generate sound or other cpu work, which interferes with the signal, giving some "cloudy" effects …
let me follow you,
just want to try w/o the pcb,
inside the pc psupply:
do i have to put 2 caps in the +5 v and ground -connected?-
and the other +12v and ground then all to the speccy? -

Not sure at the moment (I presume the Spectrum+ therefore had more than one motherboard issue in its production lifetime). When I get home I'll whip the covers off and take a look (also, I presume the issue number will be printed somewhere on the PCB) -

Have a see inside it - never know, it may have the maker's name on the PCB. If you DO open it though, I'd really appreciate a pic or two of the guts. -

No probs HH, you're very welcome - by the way, if you made this board from SMD components, I think you'd be able to get it on a PCB the size of a postage stamp. Be a right sod to work on something that small tho!! -
