So then! IMHO you just need to successfully link the senior address somewhere and that’s it
with a minimum There were alterations and the Pentov cache was there, and the second half of the microcircuit
was usefully used.
And you can use the subject to block writing there...

All the best.
With respect, Roman Milukov.

It is only incompatible with addresses. The essence, I think, is the same.

Send it, it’s me, just a bigger battery, like 6ST180.:)

Actually, we talked about this topic for a long time, but I think
(I would like to DR:) that others are also interested in this. My opinion
is this: Write (I will write :)) a new version of the pzushka, where to use it.
Distribution - under the typdos half and under the bass 48 half.
Hang the recording latch on .... subj...:). It is possible to use
the bass half as a cache (double fetch or
cut). Here it is in a nutshell. It will be steering.
About the price. I ordered (I'll go pick it up tomorrow) for 25 thousand. If
they brought it, eat it.

For now here:

there will be a new soaper??? Are your wishes accepted???
1) waaaasssssyyyyyy....
2) After “Exchange stopped” he writes: ok, I’m going to the terminal -
but the session ended unsuccessfully.
3) On my splotch 14400 1.80 it took a very long time to lay the pipe,
1.79 I laid it faster, but hung after that :( The problem
cannot be circumvented???
4) Is it possible to print the EMSI protocol data in a cultured manner,
and not in the formheaps of who-knows-what???
5) My boss has two lines to the city. How can I do this so that, without having to navigate through menus, they call in turn
this way and then that???
6) It happened several times that when writing to a disk
a piece of 65k it timed out (at 14400), then
it was netmail, and I had to download it again and again,
hasn't put 12000 yet.
7) You need to poll some button about
boiling the file. - send to the other end - they say, everything has already been leaked.
Sometimes it’s very necessary. You'll get tired of twisting your hands.

I hope you understand.

That's it, I completely lied....:)

Renat.

Working with this cache goes in four bits in port #xx7E (there is write protection there), and the beauty is that the firmware is shoved into one bank instead of BASIC128 (the same BIOS), and into the second bank you can push DOS (even the one with the ramdisk), at the same time. At the same time, the main cache remains free for the user - hear all sorts of mods or install debuggers ;)

You can use the second bank without any problems, I'll tell you when I'll throw out the scheme.

ps: yesterday I found rst7 on my own... two days on the origin like
and never happened :)

With the best, Denis.

This infection has its own port, with four bits, one of which is write-protected. But... the main thing is the idea ;)

Don’t sit on the keyboard during the session ;)
the break was stupidly made there - the error flag was not transmitted.

It didn’t hang - that’s why it took a long time. And for me it took a long time too (although it didn’t hang before),
I had to do it specifically for sprats (MD ;)

There is an option to write out every 32K, or yell at the boss to avoid timeouts
increased :)

it’s already ready, all that remains is to assemble the parliament and vote

With best regards, Denis.

On the “A+L” buttons, exactly two, so as not to accidentally press them.

...
DD> Work with this cache is carried out with four bits in port #xx7E
So it’s necessary to fence another port! :( Well, you can solder another 62256
on top... but it’s unaesthetic! :) I also installed this one so that the RU17s wouldn’t be sculpted on top of each other.

DD> at the same time. At the same time, the main cache remains free for

IMHO this can be combined. A debugger in the cache is mainly needed with standard TR-DOS and the BIOS is not needed here. And fashion too...

It was necessary to do optionally: 1.DTR, 2.pluses to slow down.

And so the CPUs are low, and they will drop... It may make it possible to
load files into memory. After all, at the beginning of the session, the volumes of received mail are known from EMSI, and if it all fits into memory,
then why not throw it there, and write it off after
the end of the session... Well, if it doesn’t fit, take bites :))
And it’s useless to shout at my boss... Only you can in forehead
get...

Well, if you are from a sophisticated shell that plows through the BIOS, you want to listen to mods
? :)

Well, it’s not necessary to immediately have a sea of software. The person who has
this uses it mainly to connect new versions of DOS.
IMHO it’s also not bad, especially if you don’t put trdos in there, but put the BIOS in there - well, and
precious RAM for system variables is not required - everything is there sitting.

RM> On magic!!! :)))

On DELETE !!!

2DD: We need support for _diverse_ memory!
For example, I have scorp-512, and this “myler...” will tell me more
tales since 128. :-( :-E~~

Denis, why are you saying “what if, what if”? You can, of course, hang up a bunch of statics,
attach an additional ROM, a screw, a SIMM 4 meters...
But somewhere you have to (don’t stop, no!) just know when to stop?
I, for example, don’t listen to fashion, it’s not interesting to me.
Imho you need to hang up new navototas carefully. After all, Speck, according to his ideology, should
remain a simple machine.

no, that’s right, of course, everyone an extra chip on the speck spoils his face
(damn, I just want to say it - like another piece of cake on Billy’s face ;)))

Yes, that's true. Therefore, General Sound & General Graphics remain only in
dreams:(

May you have memory too, and everything else! And the soap in general can be considered a derm version, I made it for myself, and then it went ooooooo ;)

By the way, how is it: Scorp - 512? via GMX?
how to get it? (doka, if possible ;)

With the best, Denis.

programmers.

DD> So, you just named this measure ;)
:))) Everyone has their own measure! ;) One doesn’t have enough money for a screw, another’s hands are too crooked to hang it up, the third is lazy, and for someone “128K+flop” is enough. On the other hand, someone constantly needs more and more, but this way you can simply kill the machine - without even shaking your hand with a 40-watt soldering iron - the computer will simply die from obesity. :)

Scorp is like a scorp, all yellow...
But the 6 and 7 bits of port #1FFD also switch banks to addresses
#C000-#FFFF. In short, everything is just like on the Pentagon, only the port
is different. And you don’t need to bang the 8th can!
In general, it would be nice to have a setup where it says which cans
can be banged and which ones can’t - my resident converter will be killed.

We, too, now have BBSs that have begun to die out, soon probably only Fido
will remain - after all, what for BBSs when users have Internet? (this is the logic of sysops).

Well, this is natural - many close for the summer. I was shocked when this year, on the contrary, stations began to connect to the 500:95/* network...
Maybe the improvement of the software had an effect...

And you once stuttered about the Internet in ZX.SPECTRUM. Can you shed light on the problem of the subject?
