retrobits | Commodore 1902 CRT Monitor Restoration: Recap, Retrobrite, and RGB mod (Part 1) @retrobitstv | Uploaded June 2020 | Updated October 2024, 5 hours ago.
Ep 5 : The Commodore 1902 CRT monitor - performing a full recap, modifying it for analog RGB input,
retrobrite treatment, and attempting to resolve some vertical synchronization issues.

Note: Switch and V-Hold issues were addressed in this subsequent episode: youtube.com/watch?v=NzVJnB5nbEI

Correction: Analog RGB input requires csync, not separate h- and v-sync as stated in the video. Digital RGB input requires separated sync signals.
