THS 7316/7317 and 7374 video amplifiers. For another day.

This thing promises to be amazing.

Since it's midnight already here, for now only a test circuit. Channel 1 (yellow trace) is the composite in, channel 2 (red) the composite sync, channel 3 (blue) the vertical sync, channel 4 (green) the odd / even field output. Works as expected.

Application A:
Separating H- and V-sync out of the composite sync to drive a monitor that can do 15.7kHz but needs RGB+HV.
Just AND the composite sync and V sync together and invert the result. Do not forget to use a buffer gate for V sync and to terminate all your outgoing and incoming transmission lines with 75 Ohms, or else the reflections will mess you up.
Yellow: composite sync, Purple: V sync, Blue: c&v, Green: ~(c&v) = h sync, directly at the transmission line, hence the low amplitude.

I finally snatched Crystal for a good price! Now, this has been battery modded before but the way it was done... Holy moly. The battery was just shoved in-between the lugs of the old one. No soldering done. Only held on by tape. Also, a CR2032 fits fine into the GBC shells.
