Poor and unhappy users Profi!
For six years now they have been suffering from
what's in games and demos, sprites and runners
the lines twitch defectively, flicker or
they all disappear.  Many of them know that
the problem is in INT, and many probably try
tried to do something about it, but nothing
this did not work out because the architecture
Profi well, very special.                 
                                          
                                          
The creators of this computer did a very
cunningly and cleverly: instead of betting
a bunch of logic to isolate the necessary signals
cash types KSI, SSI, PAPER, BLANK etc.
they installed only one RF2, recorded in
her timing diagrams of signals, and on ad-

the synchronization pulses have already been mixed into
a single synchronization signal directly
but in the chip. The situation at first glance is hopeless (yes
and on the second one too) - the only thing that can-
but what could be done was to “re-do” it again

mu), but of course the amount of programmatic

if thisproblem didn't work
POLTERGEIST,that is, me!                   
                                          
                                          
 They brought me Profi six months ago and
demanded that his INT be remade with a more lenient
who doesn't look like anything at all,
to a less right one, which at least looks like
something. "What?", I thought then, - "after all
if you correct it in Profi INT, then you can use it
but it will even look like MULTICOLOR, because
its raster coincides with PENTAGON's,
and the memory is transparent", and I started doing this
serious problem.After a while I
came to the conclusion that there was “little bloodshed” here
there is no way around it and the simplest thing is to change it
RF'ku. Well, that means I desoldered the microcircuit,
considered, moved INT to a more correct one
place and was already ready to take it to the "pro-
sewing", how the devil pulled me to look into
bit RF'ki, which on the diagram was listed as 
unused.                           
                                          
                                          
   And what do you think I found there??!    
                                          
                                          
 Yes, nothing more than a clean personnel
sync pulse Thus, the axiom of the principle
showing that everything ingenious is simple, confirms
I struggled once again.                   
                                          
                                          
So here's what you need to do to INT
became more correct and even started working
MULTICOLOR:                               
                                          
                                          
1) Turn down your sistem2) ... Oops!  Yes, I forgot that you are not stupid
 IBM's  users, and  more knowledgeable
SPECTRUM's.  In short, find it at the bottom
board of your Profi, a big cockroach
which24 legs. Find 13th leg (legs
count counterclockwise starting
from the key) and cut off the road leading from it.
Throw the cut road onto the 14th leg and
after this INT you will have, well, practically
PENTAGON's. Phase of SSI relative to SSI
in  Profi  slightly  different than in
Pentagon and because of this there are curb stripes
will be moved to the side. At one time I
I didn’t solve the problem, but now it’s already
it's too late, since there is neither Profi nor schematics for it,
I don't have it on hand. But it might be
Wiring is also no more difficult. In short, I think that everything is clear even to those
who doesn’t know which end to take the pa-

Yes, by the way, if you want to re- enable INT from PENTAGON's to "branded" then you can spa- Take everything according to the diagrams given below. The first option is more simple, but the second scheme is more- more noise-resistant. (Tracks with arrows on picture must be connected to shaperINT)
And finally, I want to warn the program mists with Profi: do not sync MULTICOLOR for this newer INT - yours creations will most likely glitch (slightly!) on the same PENTAGONs. Well, now allow me to shuffle around and say goodbye: POLTERGEIST was with you From Samara 13.02.97 P.S. Don't forget to look at the advertisement! O:> From the editor, I would like to say the following due: today, in Samara there is no there are practically no known ones left us Profi, not converted according to this scheme. Imagine - a whole city, and nowhere to look at the glitches! As you probably realized, after this modification, it starts working not only MULTICOLOR, but also stop jerking put sprites and scrollers into music demo! The border really remains somewhat different than on PENTAGON, but this is not true important. The main thing is that if the effects go at the top or bottom of the curb, they are almost the same! It's time- significant for all of us it was that the only and unique set MULTICOLOR effects written by Samara programmers ( part from GIFT FOR M.M.A (SPEED CO.'96)) is on the converted Profi, as on a live PENTAGON, under which ry she actually synchronized in within two weeks!And this is not to mention that MULTICOLORs work without problems in SATISFACTION,INSULT,ECSTASY,ENL'96 DEMOS, BRAIN CRASH and many many others! -═════════════ - * * * * *
