I remember zeno posting about how Zenith built a 9-57-VCR horizontal module for their Chromacolor II TVs so they would work better with VHS decks (no flag waving and such) in the era when Zenith was backing betamax. The module was supposed to be basically a stripped 9-57 with a 9-90 piggybacked onto it. Matt 'Tapes' Steck figured out how to make one (it takes the H-hold coil out of circuit) and posted about it on Facebook. I figured Zeno would like to see, and it might be helpful to others.
