The attached program will disable Extended Color BASIC on a CoCo 3.

Here is a more sophisticated routine which emulates ECB's TIMER via the USR() function. e.g. "PRINT USR(A$)" is the same as "PRINT TIMER". "T=USR(A$)" is the same as "T=TIMER". "A=USR(32767)" is the same as "TIMER=32767". "X=RND(-USR(A$))" is the same as "X=RND(-TIMER)". 10 'TIMER FUNCTION V1.0 20 '...

The following routine can be used to add a TIMER substitute to a CoCo with Color BASIC only. This routine is useful for randomising the RND() function. 10 POKE243,190:POKE244,0:POKE245,254:POKE246,48:POKE247,1:POKE248,191 20 POKE249,0:POKE250,254:POKE251,126:POKE252,169:POKE253,179 30 X=65283:POKE X...

The following routines can be used to disable Extended Color BASIC on a CoCo 1 or 2. The machine will restart in Color BASIC mode only. These routines are useful if you have written your own program, and would like to test it on an unexpanded CoCo. 10 'ECB DISABLE V1.0 20 'FOR THE TANDY COCO 1 AND 2...

I am compiling a concise reference list of all CoCo cartridges. The list below was compiled from cataloguing my own cartridge collection, and some research on the internet. Please let me know if I missed any, and I will update the list. Regards, Steve Tandy TRS-80 Color Computer Cartridge List =====...

Thanks Ciaran! I appreciate you taking the time to try this test. As I suspected, both MESS and VCC suffer from this serious flaw in their emulation of the CoCo 3 hardware.

I would be grateful if you would try that little test.

Thanks for sharing, Jim! BTW, you forgot the mention the new game "Pipe Frenzy" that you wrote for the CoCo Coding contest.
