It is certainly way better than I ever remember. I think I'm just spoiled with expectation after using the VICE emulator and typical PC displays. The image I get on my plasma TV is severely ghosted - far worse than this image which was from a small LCD TV.
I might try one of those S-video to...
Yeah I only have an iPod for taking pictures. On some of the blue characters I can see pink/purple ghosts of the characters to the left and the blue pixels have dark edges on them (same sort of 'spill' that you can see on the left of the screen). Given that I have introduced 'white' ghosting in...
Hi. I've given up. No matter what combination of things I've tried tonight, I simply cannot get rid of the dark lines on the edges of pixels. I managed to introduce "white" ghosting in various amounts but I cannot get rid of these dark edges. I tried putting the delay circuit on both chroma and...
Yeah I made the cable previously. The Audio goes down seperate cables into RCA connectors so its definitely a 4 pin S-video cable. The computer (and old Commodore Vic20) never had S-video previously. I made a modification to the motherboard to get the seperate chroma and luma signals and...
Thats pretty useful, Brad. I need to solve the ghosting for an NTSC and PAL machine so I'm going to make a shielded box that will handle the two different delays. Just need to buy some S-video male/female plugs first before I go ahead and give it a go. I'll report back with the results (or...
Thanks Brad. I bought some 1.5uH chokes (hope these are truly inductors!) and 270pF capacitors yesterday. (11 of each). I worked out the time delay as being 20ns for a pair of each.. so I should be able to create a delay of 180-220ns in theory. I haven't had a chance to try them out yet and...
If I use 10 pairs of components, is it just a matter or putting the 10 components in series? In an DC circuit I would expect the resistance to become 750 ohms.. In an AC circuit will the impedance remain at 75 ohms if 10 pairs are used in a series chain? Thanks
Update: Our one and only...
Thanks for having look. Do you know what value of L and C I'd need? If I wanted to vary the delay from say 100ns through 200ns, which component would I need to buy as a variable? Can you buy variable inductors?? From memory you can buy variable capacitors as thats what you have in a radio tuner...
Hi, I'm somewhat inexperienced in electronics (I've soldered wires, cables, made a few circuits with 555 timers etc). I have an old vintage computer that I've just rewired to with with S-video.
The problem I have is that the luminance and chromaticity signals are slightly out of phase which...
