Double permit ZX-SPECTRUM
(C) PAWEL / RS
Judging by the publications in electronic editions dual
resolution starting to support a growing number of programs.
This of course good, but there are a large
BUT - this is the compatibility of these programs
various glands. After all, there are several types of computers
in which such bells and whistles incorporated initially (PROFI
and etc.). I, for example, working on computer
Local production of electromechanical
Concern - Bayt 01. " In Byte 01 inclusion
double resolution by installing the 7 th bit in the port 5. The
remaining bits used to set global (for
the entire screen) attributes. For example for
the inclusion of dual-resolution black
PAPER'om and white INK'om necessary to send
to port the # 87. Well at least the structure
and address of the additional screen area
the same (# 6000). Previously, I had no idea
what is available in my Byte 01 double permit me someday prove
useful, but as in C / PM (disk operating system,
for those who do not know), but now there is software that
supports dual-resolution and I invite all of its developers to
build SET UP, where you can set the port, the bit is
responsible for double the resolution and setting the remaining
bits arbitrary state. Only then will we
arrive at a consensus:). After all, not good if the group will
release a REAL SOFTWARE product that will only work on
Byte 01. And plans to launch a new group
text editor, and who knows, maybe
he ever will get support
dual solution. Modes 64 and 84 characters per line will be
available without any distortion. By the way the development of
this editor leads CYBEREX / RS.
P. S: For those who want to learn more about double the
resolution and hang myself this pribambas recommend reading
ezines ZX-POWER 2 and DEPTH 2.
