- HeyLaughingBoy 6y agoThen you need to know POKE 65495,0 :-)
- ddingus 6y agoIndeed. I just got a nice, old CRT for use with my retro machines. A CoCo upgrade and jam session is in my future.
- Zuider 6y agoIf I recall correctly, that instruction doubled the clock speed of the M6809, usually at the expense of making it go out of sync with the woeful 6847 video chip, putting colorful garbage on the screen.
- ddingus 6y agoWhen that happened, I think it was on the CoCo 1 and maybe 2. The three can do it with no worries. And the 3 didn't use the 6847, but a custom ASIC.
- HeyLaughingBoy 6y agoIt was OK on the CoCo2. ISTR doing it for some games I wrote in BASIC.
- ddingus 6y agoGood to know, LOL. We are so late on this chat. Fun stuff.
