POKEing Around The Color Computer
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 Adirondiack Color Computer Club in New
York state. These might work on a Dragon too- please let me know.
I should also mention that I have added several pokes which were suggested
by people who have viewed this list on the internet.
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.
POKE 65497,0 on Coco 3 double speed of RAM and ROM. Printer, disk and
cassette functions won't work.
POKE 65496,0 puts machine from double speed ROM and RAM back to normal
speed.
POKE 65495,0 doubles speed of ROMs; Basic programs by 1 and a half. Does
not work with all computers, or with disk, cassette or printer operations.
POKE 65494,0 puts ROMs and Basic back to normal speed. Cassette, printer
and disk works normally.
POKE 65315,54 disables cartridge takeover, allows you to put in a Rompack
without it starting up. NOTE: the use of this poke to put in a cartridge
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
loaded off of cassette
To put a 64K Coco into all RAM mode, where the ROM can be modified:
