Megaspectrum is dead :-( — ZXNet «hardware.zx»

From Denis Dubodil To All 1 June 2006

Hello, All With the computer and TV turned on, I plugged in the video cable (RCA). The video output booed. - there is only noise on the screen. The spec itself works. The board is Moscow128, the video is taken cunningly - it is removed from some abstracts on the diagram, then it is mixed with logic 555. I connected it to the TV according to a b/w circuit - ground and synchro(?). There was a black and white image on the screen. Who died? Logic or something on the board?

Hello Ronin Ron> are the wires coming off the video? :) well, further along the circuits - the board, Ron> no soldering, capacitors have dried out... The wires are fine. The computer has not been understood since normal operation. Non-solders are also excluded. And it didn’t die right away. Synchro went out first then the image disappeared. What could this mean?

I can only advise in the future to tie together the chassis of all devices wire with a really large cross-section. > The video output boomed - there was only noise on the screen.
