(C) 1997 V.M.G.
------------------------------------------
MAX>The application contains a terminal
program "MELON",using extended
Spectrum screen up to 512 dots per line.
So that the reader does not beat his head in hysterics
about the monitor due to the lack of such modification
ki on his computer, I decided to smear soap on his
I sew a rope and place the diagram in a journal.
Material taken from the Kharkov magazine "ZX-
POWER #2" (are you still alive?) with virtually no
changes. This development was carried out
famous V.M.G. And a word to him:
The era of magazine creation, in my opinion,
negatively affects users and hackers.
If demo-making by its very essence
was disinterested fun and allowed
sloppiness, then the laws of the market are
impose strict requirements on form and content
zhanie magazines, change their attitude towards their own,
and that means someone else’s work. In Kharkov for-
the number of “breakers” has noticeably decreased,
it became unexpectedly difficult to get a ball
a copy of the new version of local software, even
out-of-town magazine or game, and this is ra-
blowing The coolest protection should not be on
track zero, but in your own head.
The word in the West replaces the round seal not
because of some kind of superiority in spirit
ness. This is a subconscious agreement:
Don’t let others down, and they won’t let you down.
When you break someone else's program, someone...
then on the other side of the mirror it breaks yours.
Of course, Nature cannot be changed, and someone
something always, in retaliation for his suppression
lazy childhood, will destroy telephones
booths, write obscenities on fences and run
computer viruses, but these are loners and
the rose is not from them.
Therefore, let's boldly change the folded
existing stereotypes of relationships, forgetting about
old grievances and freshly broken firewood,
after all, only those who did not make mistakes were not mistaken
did.
Now let's move on to the hardware itself.
Today we are publishing a scheme for increasing by 2
times the horizontal resolution of the screen
SPECCY. After modification it will be possible to PROG-
RAMMON enable the mode "512 points per line"
ke". Specific recommendations are given to the authorities
businessmen "Pentagon". On "PROFI" and "ATM"
this mode is implemented, about "Scorpios"
there is someone to take care of without us, and the owners
other machines can contact the editors
"Black Crow".
The scheme has been developed and tested very
long ago, but has become relevant due to
by connecting proprietary modems to SPECCY.
The fact is that computer networks work
in "80 characters per line" mode.How is it
looks like on a regular Spectrum screen,
better imagine it yourself. We have to resort to
to a small modification to make it 2 times
increase the number of horizontal points.
The improvement is really minor, because...
depicted inclusion ID7 and the following
trigger (TM2 or TM8, TM9, IRZ5) input
inserts into the modem connection diagram via a multi-
tickart and can be used from there
or saved there.
Naturally, it will take 2 times
more memory for the screen. For this purpose
area #6000...#7800. In the remaining
unused area #5800... #6000
all system
variables and short BASIC programs (for
loaders).
SOFTWARE.
The main Kharkov software developer,
supporting almost any brand-
new modems based on SPECCY, (VIC) uses this
improvements in your terminal program.
-----
MAX> It was assumed that the modification would be applied in
"revolutionary project" AL-DOS, but because...
the revolution did not take place due to a blockage
project, then the editor is no one to him, then-
I mean, I didn’t write about the project. Here is the program-
manage for yourself now...
-----
Notation asalways, given according to
tern scheme"Pentagon",but with a more
regular numbering of addresses (A0...A15).
OPERATING PRINCIPLE.
Increase horizontal resolution
achieved by doubling
clocking frequencies of IR16's D41 and D42
(9_IR16). At the same time 2 times more often
they are loaded in parallel 8-
bit code by replacing one of the hour-
the one on the 5-D5 computer. At the same time, the second
sampling is made from ADDITIONAL
REGISTER D38`, soldered to all outputs
D38. Inputs D38`, including pin 11 connection
deal with those of the same name (having the same
number) inputs D40. To the 1st outputs D38 and
D38` signals are sent from the 9th and 8th pins
Dov D15 respectively.
Attribute register D40 is converted to z-
state and its outputs are set
code 7 (black PAPER, white INK) using
5 resistors of 1k each between the terminals
9,12,15,16,19 microcircuits and ground (on
resistors are not indicated in the diagram!). To avoid
"flickering" on the screen can be set
also 1k resistors between the terminals2,5,6
этой микросхемы и +5V.
ПРОГРАММИРОВАНИЕ.
После сброса всегда аппаратно устанав-
ливаетсяmode of conventional Sinclair ex-
wound. Program output to extended re-
pressing and back is carried out by setting
by resetting bit 1 port #EFF7. Use
The use of extended mode does not affect the
held RAM, i.e. in this mode THERE WILL BE RA-
BOTTOM any existing program and
BASIC, but with semi-nonsense on the screen. At address-
itself #4000...#5800 even columns are stored
screen (0...62), and #6000...#7800 - odd-
nal (1...63).
