     Double permit ZX-SPECTRUM

   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.
