edited May 2002 in Wanted
I am searching for a monitor interface,
so that I can use my Speccy on a computer monitor.

    first of all you need some old CGA/EGA monitor, since most of the VGA monitors can't cope with the vertical refresh rate of 15kHz
    then, if you have speccy 128 you are almost ready, you only have to make three AND gates to deal with the bright signal (standard AND gates are supposed to use +5V and two diodes, but i hope for our purpose this can be done only with a resistor and a diode, i n fact i wanted to do this myself for a long time but had no time to get down to it)
    otherwise you have to make a convertor YUV->RGB, i think the schematics can be found here http://members.tripod.com/~piters/zx.htm
