jwse30 Posted April 8, 2022 Share Posted April 8, 2022 I recently picked up a coco3, and naturally, I’ve got to upgrade it. What are my options for RAM, and how likely is it that any of those options will be available at CoCoFest next month? Thanks in advance, J White Quote Link to comment Share on other sites More sharing options...

brain Posted April 8, 2022 Share Posted April 8, 2022 2 main options: 512kB 2MB Lots of vintage and new options for 512kB. Less for 2MB, but both should be available at CoCoFEST! Jim 1 Quote Link to comment Share on other sites More sharing options...
Michael Kline Posted April 8, 2022 Share Posted April 8, 2022 Ed Snider at https://thezippsterzone.com/ has 8MB RAM for the CoCo 3. You'll need to contact him direct to inquire further. Anything above 512K is usable via OS9/NitrOS9. Quote Link to comment Share on other sites More sharing options...
MrDave Posted April 8, 2022 Share Posted April 8, 2022 You can use 2 meg from Basic if you wish Quote Link to comment Share on other sites More sharing options...
+thanatos Posted April 8, 2022 Share Posted April 8, 2022 If you just want to play games, 512k should be all you need. The Triad from Cloud9tech is a great product. Runs much cooler than the original upgrades from back in the day. Quote Link to comment Share on other sites More sharing options...
MrDave Posted April 9, 2022 Share Posted April 9, 2022 You can do alot with 512k .. and yes the new boards runs so much cooler ! Quote Link to comment Share on other sites More sharing options...

MrDave Posted April 9, 2022 Share Posted April 9, 2022 (edited) Basic won't automatically use 512 or more but you can use pokes to map in 8k chucks of this ram and store your data and images there.. Like this basic program i wrote..it uses loadm to load a whole disk in ram .. but its controlled from basic.. standard joystk , inkey stuff. Rick Adams put my code on github..

J White I recently installed one in a CoCo3. Works great! Just be aware you have to cut 2 resistors on your PCB for it. Quote Link to comment Share on other sites More sharing options...

I think they were capacitors, if I remember my upgrade process with an original board 30 something years ago... Quote Link to comment Share on other sites More sharing options...

Yes, you’re correct. C65 & C66. I thought something was off yesterday when I typed it. Quote Link to comment Share on other sites More sharing options...
jwse30 Posted May 17, 2022 Author Share Posted May 17, 2022 Well I picked up an old used 512k upgrade from Cloud 9 for $15 at CoCoFest. If this one doesn’t work out, I’ll order a triad from them. Now I gotta find time to install it J White Quote Link to comment Share on other sites More sharing options...
