[Coco] 64k memory check

[T. Franklin]

iff memory serve (pun intended), that can only be done via a machine language routine. The problem is that those coco's had the upper 32k mapped into the same spot as ROM and the interrupts need to be disabled. The rom switches off and the poke command would not be operable any more. There was a small binary app that copied thr ROM to ram but it didn't actually test the upper 32K of memory.

Hi guys,I just aquired a Coco 1 (grey) Cat 278-300A., CCR-81 Cassette Recorder, X-Pad and a few carts and tapes.The Coco powers up fine.Extendended Color Basic 1.0PRINTMEM reports 24871Since this is an "F" board and the "F" boards were the first Coco 1s actually "meant" to be upgraded to 64k, I assume it is 64k.The warrenty seal has been removed and replaced by a Radio Shack Service Center seal, so I would think it had to be upgraded by Radio Shack or the seal would be broken. What I would like to know, and I know it's been discussed many times before, is if there is a PEEK/POKE or short routine to test for 64k? I plan to hook it up to a drive and run OS-9 Level 1 and that will surely fail if it's 32k. But if there's a quick way, that would save me a lot of troubleHere a link to some pics of the Coco 1 and accessories I recievedhttps://sites.google.com/site/dabarnstudio/temp-picsBill PierceMy Music from the Tandy/Radio Shack Color Computer 2 & 3https://sites.google.com/site/dabarnstudio/Co-Webmaster of The TRS-80 Color Computer Archivehttp://www.colorcomputerarchive.com/Co-Contributor, Co-Editor for CocoPediahttp://www.cocopedia.com/wiki/index.php/Main_PageE-Mail: ooogalapasooo at aol.com--Coco mailing listCoco at maltedmedia.comhttp://five.pairlist.net/mailman/listinfo/coco
