The following is a list of Coco 1 and 2 (should also work on the 3) pokes
which were published in the Saskatoon Color Computer User's Group
newsletter, March 1986. Originally they were taken from The Color 80
Journal newsletter published by the Adirondack Color Computer Club in New
York state. These might work on a Dragon too - please let me know.
Important Ones
POKE 65497,0 on Coco 1 and 2 double speed of RAM and ROM. It will cause
your screen to fill with garbage, and sometimes causes memory to disappear.
Printer, disk and cassette functions won't work.

with the machine power on can cause damage to your computer. It's use is
not recommended.
?PEEK(487)*256+PEEK(488) start address of last machine language program
loaded off of cassette
?PEEK(126)*256+PEEK(127) end address of last machine language program
