Hello,
Scandoublers are quite complex.
I am designing a scandoubler using devices from Averlogic and Samsung, it has 2 off 100 pin parts and 1 off 64 pin part. Pin pitch is around 0.65 mm, fun to solder! :-o I'll post more when I am finished.
There are Syncdoublers which 'fudge' the 15 KHz scan rate but distort the picture, see
Syncdoubler.lha hard/hack 273K 422 Show 15khz on VGA Monitor, no Patch
Have fun
