so I’m saying that the VGshka is making noise in another computer!
Christmas, could this be due to the fact that part of the RAM is RU5 and RU7?
what kind of nonsense is that?

no, this does not happen, it happens that when exiting TR-DOS (after directories,
sheets and breaks) it resets, or freezes with 3 horizontal bars
across the screen (software)

already changed TM2 - without results :(
for me64K, pzushka, as I understand it, change it or something (everything is there)

it's shit, and multicolors are mostly riveted under it ;)
yes, me too, something happened, but what?

it doesn’t just reset, but if there is a break with CAT or LIST, and when
exit via RETURN it usually crashes, although this didn’t seem to happen before
at 14 and 8 MHz

oh, if you scan it, then it will be wretched :(
although if only the circuit controller,
only I can’t get into it - why did I start resetting,
and what’s most interesting is that with different VGs there are sometimes fewer, sometimes more
glitches!!!
thanks for the advice, I’ll try

it may very well be!!!!
because I, so to speak, exceeded 512K, and I have 7 rubles - RU7
how do you know that it’s the address ones????
maybe it wasn’t that at all? :(
tell me more about your glitches, I'd like to compare!

Anything... Try to grasp the system. If the same bit(s) are corrupted in all bytes
then... check the tracks/chips in the
drive controller.

Good luck! Evgeny.

TEV> I’ll start, then it’s completely insanity!

If only when reading from a disk drive, check the buffer elements (something
like LH3 in the controller, and if you constantly check the controls, most likely
the memory is buggy.


With all kinds of regards and wishes.
Igor.

It doesn’t look like a memory error!
I don’t know the Pentagon, but in Scorpio glitches with the clock
frequency of the VGshka appear. Sometimes the drive glitches (rotation frequency >300).

Bye... bye bye, Sersh !
