[Coco] Coco Digest, Vol 166, Issue 36

[Pere]

Hi Art,
I am new to the CoCo developpment arena and know just a few about the CoCo3.
As the POKE&HFFD7,0 works well in CoCo and Dragon I thought that issuing the
double speed for the CoCo3 would work well ... in fact the tests I have 
done, have
been made on VCC, so I cannot speak about the real thing.
VCC supports well that double speed, the images are loaded faster without 
problems.
If it were just a matter of changing (doubling) the value of a few bytes to 
compensate
for the double speed, I could add these changes. Could you give me any 
pointer to
know what places should be modified (for reading and writting)
The program calls the FREE, CLOSE and LOF commands too
Thanks in advance
pere

This sounds like a bad idea if you are doing disk I/O at double speed.  The
CoCo 3's disk routines must be modified to do this reliably, on account of
insufficient delays at double speed.
