What would it mean
Who saw my View Screen versions 2.0 through 4.0,
have noticed that if you include a picture show on CP / M
screen and press the 'V' - views, a Spectrum screen will
quickly switch to the CP / M'ovsky and back. After a few tens
of seconds at Spectrum will screen vylazit any delirium,
altered attributes. Just spoils Advanced screen. Some time
later, the machine will hang or reset. I thought it was a
glitch my program (eg, stack overflow), but totally dug it, I
found no errors.
Dial little program:
LD BC, # DFFD; port PROS
L1 LD A,% 10000000; includes an advanced screen
OUT (C), A
XOR A; includes the usual screen
OUT (C), A
JP L1; repeat
After a few seconds, blinking screen machine will hang or
reset.
From the programmer's perspective, there is no error in
the program, but comp buggy. If you want to watch, as it
happens, then after postavte OUT'ov dvatri HALT'a.
The explanation for this must be sought from Gluck
zhelezyachnikov, those who know the structure of the computer.
I have the same coder, and I can not tell what was going on.
And really, what?
