Pentagon128 --> Pentagon512 !

TEV> what am I after all ;) time hasn’t passed yet, and I’m already struggling with my
TEV> problems ;(

So that’s how it should be.

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

Yes, the cable is too long. :-))))

I met it, it still works unstably, faster RUKHKI is better.

The delay, the front becomes flatter, and the level drops, and therefore
the front drops from the element’s response level.

Bullshit, someone will write this driver.

TEV> how unstable? if I’m just stable! there are RU7I
TEV> before that there were RU5B, V, G, D - everything was mixed up and there were no problems!

How long will this machine work without failures, with good
warming up? When heating up, they can rarely glitch, although there are
exceptions.

TEV> I’ll write on the next page about replacing the buffer in Leningrad. week because
TEV> no time

OK.

by the way, no one will say what kind of insanity - I had a computer with 48K RAM, the control units barely warmed up, upgraded to 128 - they just became boiling water!!!!
why is this so??? and how to deal with it? someone recommended installing air conditioners for food - it didn't help! :(

TEV> I think this is not an exception, but simply flying out RUSHKI, my friend
TEV> fights with them like this: I bought a cooler PTsshny, and that’s it, no problems;

The cooler is a solution not worthy of speckie.

TEV> and now how I deal with it: I cover all the RUSHKI tightly
TEV> tightly (previously I just put an envelope from a floppy disk), and on top there is another
TEV> some kind of weight,
TEV> and I leave it overnight with a test ROM, look in the morning - which one has flown out
TEV> or flew out overnight ;) and change it, this is how I fight! if you have
TEV> of course
TEV> there is something to replace it with, and such a “salad” from different RUSHKI works without
TEV> problems!

If you heat it with a 100-watt lamp from 10 centimeters, an hour will be enough, but all the same
then this salad may glitch.

TEV> by the way, no one will say what kind of insanity - there was a computer with 48K RAM, RUSHKI

TEV> why is this??? and how to deal with it? someone recommended

Perhaps the fronts of the service chips are not very sharp, and there come
moments when something has already worked, but something has not turned off (after all, the switches are in
parallel). And for some time, more current flows through the switches. The entire logic of the serviceYou can
try to set it to 1533 or use resistors to make the rises and falls steeper, so that
the states go away in Z. Everything! :-)))) Looks like a
load perhaps? :-))))

ahh, well, if that’s the case! Well, if the whole Spectrum is wired, then
you’re already afraid to touch it ;)

> TEV> but that wasn’t the case, ehhh, it’s a pity, it was a good computer ;-)
> Oh well, I’m kidding! :-)))) You can make it work well.
So I was joking too, but a normal computer works too,
just think about 0.5 Mega RAM!! 8-)
not 512K but half mega!!! ;)

I spoke with one creator (Minsk version) - ARS/Fatality, so
he says that you can use a regular trance from your phone or by yourself
wind it up ;)

>> reaches 0.7 volts in some areas. SHIT!
TEV> okay, that's it! How tired I am of these exclamations towards the Pentagon - “shit” and

no, you know, when a person has had a lot of trouble with all sorts of upgrades
and other things on the Spectrum, and he still has an offer to
tug him, then he is ready to send him to hell ;)

especially now that they threw in the drivers :)
by the way about copiers - it’s enough to copy an entire disk
in 2 times ;) we should also increase the memory or something ;-)))
it would probably be easier to get another drive

Either Robert specifically drove it to me, or not, but the former is unlikely, since he himself did not make modems for months due to the lack of trances. And for others the level weakens greatly, as he said.

TEV> no, you know, when a person has suffered a lot with all sorts of upgrades
TEV> and other things on the Spectrum, and he still has an offer to tug it
TEV>, then he is ready to send him to hell ;)

:-)))))))) Not, if it’s not buggy, then of course there’s no need to touch anything.

TEV> especially now that they’ve thrown in the drivers :) by the way, about copiers -
TEV> it’s enough, let’s say copying an entire disk in 2 times ;) we need to expand the memory
TEV> or something ;-)))
TEV> it would probably be easier to get another disk drive

Well, a megabyte is definitely not needed anymore, and everything will be fine, the only thing meg
it’s better with is-dos, where the disk is copied into the frame with something like acca, and
on completion of the work it’s back again.

TEV> I don’t know, I don’t know, so we’ll wind it and we’ll see there

I’m also interested in what will happen.

TEV> btw, did it reach you or what??? (mem1)

I received it, I'll take a look today.
