Pentagon128 --> Pentagon512 !

From Tyukaev Eugene Vladimirovich → To All 25 November 1997
Hi All! has not yet gone beyond 128) everything is OK, as soon as it starts to go higher
then the rake immediately starts in the form of some stripes on the screen, freezes, well, in general it flies, I don’t even know what it is,
although I redid the regeneration, changed the buffer (IR23 to IR22)!
who knows??? tell me plzzz!
just don’t refer me to the author of the ramdoctor, he works on
the converted Leninets1 and everything is cool, then let’s get to work??? circuit for the Pentagon,
but doesn’t want to work, that’s the left computer :(((

Dear Mr. Vladimirovich!

And on Scorp, at the very end of the memory test, the video page is filled with muck.
But when pressed, this “muck” smoothly disappears (as if it was intended that way). What
on the live, what on the emulator. Or “we emulate exactly to the point of glitches” (c)CF?
²All: does anyone else experience this?

Or maybe the doctor is left? What he writes on our local “Syntheses” is generally
a joke. From floating speed to the Pentagon.

There may be a problem in the temporary operation of the knobs. The Pentagon requires the installation of
fast knobs with the letters A, or B, or without a letter, but no more. You can
try a delay on the ras with a conder of about 100 picoforads, or in the gap of the ras
resistor from 100 to 510 ohms, the more, the more reliable. If that doesn’t help, the delay on the IR22 (or 23) memory read buffer in the form of a conductor on legs 1,or
11. If this doesn’t help, heat the guns with a lamp until one (usually a buggy one) completely flies out under a continuously running test, which is in a special ROM. Will the old proprietary sinclar test by any chance show an error from address #C000? Be sure to check and write what happened.
Sincerely, Alex from FFC COMPUTERS.

in short, everything smelled!
in general, this was the problem:
I have a cable from the RAM to the expansion board about half a meter long 8-)
and I noticed one glitch - when I changed the location of the board, then
there were more or less glitches, I took it and started with a resistor on +5V poking around
well, I found this bastard :-E (I’m sorry, but I’m already SO sick of it)!
