  1. **I tried to search and see if this topic had been discussed before, but did not come across anything concrete, so here it goes... If I have missed a prior discussion, please let me know.** I always wondered to what lengths others have gone to keep their old friends alive and kicking. Please share your story no matter how insignificant you think the repair is/was. I always love hearing how others have saved these gems from the past. If you have a picture, please post it! My contribution: Back when I started looking for a TRS-80 CoCo 2 to buy, I knew early on the RF Modulator output was going to need to go. So I did a bunch of research on how to hack the MC1372 modulator circuit so I could get composite video out. I found the answer on page 12 of the MC6847 Video Display Generator chip manual. It depicts exactly how to build the circuit. So I ripped the guts out of the RF can, rewired it in place, added an audio amplifier circuit, and added an audio output jack on the back of the can under the video. Happy Sunday!
