[Coco] Need help repairing a CoCo 2

[didier derny]

Coco 2 upgraded to extended basic, thank

Any idea why I have a 8v 48hz trapezoidal signal on the tape recorder output ?

I guess I burn the line entry of my PC ..


Is it a common failure ?

Thanks

hi, just make a copy of yours, the rom is on your board, and a BASIC program can read it with variable = HEX(peek(address)). 


you find this code in the coco archives.


I have a coco 3, and not shure my extended basic rom part is the same for coco2.


have fun

No, short white box, 16k machine

The machine was sold on ebay as "New Used"  (and later on the page  "never
used")
But I have some doubt about that :)

Any idea where I can find an extended basic rom image ?

I found some rom on colorcomputerarchives.com but There are no real description of the content of rom images

64k Coco 2 came out (manager's special $69). I think they were getting rid of some surplus parts. It was of the "8 chip upgrade" variety. The chips had to be desoldered and replaced, so I never did upgrade it because I didn't have the skills. I soon after got a 64k Coco 2.

Amazing Tandy kept selling Color Basic. I'm glad it was finally put to rest for the CoCo3.

8 chip upgrade? This must have been the long white case CoCo2.
