TR-DOS subdirectory system
ZXNet echo conference «code.zx»
From Vladimir Galtscev → To Dmitry Pyankov 18 December 1999
Turn up the brightness, Dmitry!
Recently Dmitry Pyankov, choking on another sandwich,
chewed All about the TR-DOS subdirectory system ...
[ah, how delicious....]
Sorry, plz, no invitation.... :)
Here you are writing about some directories and subdirectories...
I got an idea here. :)
Don't hit me - I'm just suggesting. If you don't like it, tell me
"go to hell with your madness, lamerrrrrrr"... ;)
Is it not possible to do this:
Let's say there are several large files on the disk with the extension
Well, let's say... uh... *.dir :)
i.e.
la-la-la.dir #ff <- length in sectors...
la-la-la.0 #ff
la-la-la.1 #10
Here. And in the file la-la-la.dir will be located... uh..
Well, let's say a fat table, all sorts of directories, files there
various... Well, in short, like a mystical disk... :)
If you want, you can copy the disk image, or you can
in a file format, but already special. copier that supports it
matter...
Huh?
Pimple, Dmitry...
From Ivan Mak → To Dmitry Pyankov 18 December 1999
Greetings, Dmitry!
<13:32> Dmitry Pyankov write to All:
DP> Have you reached here? Let's continue...
DP> So, in sectors 10..16 we will store information about which
DP> from the subdirectories is each file, file names and
DP> subdirectory information as follows:
I have to disappoint you about the 10-11th sectors. Button "Magic" standard TR-DOS
uses these sectors for temporary data storage.
And as subdirectories, IMHO, it is best to use regular files with
unusual extension. And inside these files there are sectors with a structure similar to
main directory. There may also be other subdirectories among them.
The only disadvantage of such a system is the inapplicability of conventional MOVE
Wow! The Protoss are attacking my Zerlings! It's time to get going. Ivan.

Hello Andrey!
23 Dec 99 00:29, Andrey Radziwill -> Aleksandr Majorov:

DO>>> I sometimes have problems with power supply, and therefore when I turn on

AM>> I had this on Skoppa.
AR> I laughed for a long time ;)))
AR> IMHO it's nonsense to write programs based on the fact that someone is from
AR> refrigerator magick works ;)
It’s not necessary to make software protection from the refrigerator, but what to do
if there is such an effect?
And it doesn’t have to be from the refrigerator!
AM>> The treatment was simple: the reduction coming from MAGIC by +5 was reduced to ~100 Ohm.
AR> No: you need to reflash the ROM so that during magic the inscription appears:
AR> refrigerator? (y/n) ;)
It’s much easier to remove the “glitches” of the hardware manually.
For example, in Scorpa there is a joke - the entrance to the shadow area happens magically
by reading the _second_ command!
Those. on ordinary computers like this: I pressed the magic button, and when reading the first
commands from RAM will be formed INT.
On the scorpion - current on the second team.
Why - I don't know.
But as a result, it’s hard to go into the shadows from TR-DOS.
I had to make improvements to all my scorpions,
so that it reacts from the first command...
In short, here's the joke:Sometimes you load a code block from TR-DOS and want to view it in shadow.
And _how_ to enter there?
Press magic? - damn it! While we are in ROM it does not work!
There is a simple solution - press Enter, and the percentage for one command will go into RAM
(to address #5CC2 - C9 RET: transition point to another ROM :)))
If you hold magic at this time, then nothing will happen on a normal scorpion,
and on other machines and on a modified scorpion, the magic works.
And the summary is that the magic increases by +5 something like 10...15 kilos, and it happens
that the tip is skipping...

Hello there, Kirill!
Somehow on 12/25/98 at approximately 05:32:00 someone Kirill Frolov reported
for Aleksandr Majorov that "TR-DOS subdirectory system"

AM>> For example, in Scorpa there is a joke - the entrance to the shadow area happens magically
AM>> when reading the _second_ command!
KF> Have you confused it with anything else?
no, but I CHECKED IT!!!
if you put only one RET command into RAM
and if you look at her, you won’t go into the shadows!
what if
NOP: RET - then we’re leaving!
[ ]
AM>> On skoppe - current on the second command.
KF> That is. ? Everything turns out exactly the same.
KF> Look at the diagram.
AM>> Why - I don’t know.
KF> I have a suspicion that the paper diagram of the scorpion
KF> incorrect...
I PERSONALLY observed this effect, I PERSONALLY corrected it myself!
It even seems that he showed it to Zonov a long time ago.
I remember he didn’t believe it either, but after the demonstration he believed it :-)
and the paper diagram of the scorpion in the MNI formation node is correct -
I looked at everything with a sample :)

KF> I DON ' T UNDERSTAND!!! This shouldn't happen!
this can't happen because this can't happen?
KF> What modification? I have this glitch too!
ha ha ha! 33 times!
So you started to answer at first, and in the middle of the letter you decided to check????
Just rulez!!!
Or maybe you should first read and check the entire letter, and then respond?
;-)))))))))
and the circuit is very simple - a couple of broken tracks and a couple of jumpers.
after which (it seems!) one D-trigger is freed ;-)
Look carefully at the diagram and you can do everything yourself.
And remembering/inventing and throwing a diagram here does not correspond to the topic.
AM>> And the summary is that the magic increases by +5, something like 10...15 kilos, and it happens
AM>> that the aiming is skipping...
KF> IMHO this is not a summary, but you already need a power supply - after all, in IM2 mode

KF> throw out the summary altogether.
no, you don't understand.
for me, when there was still a wicom with a "bell" when it came in
the call at the moment of picking up the phone there was a chance to fall into the shadows.
A hedgehog (even a bald one :) understands that for this you need a needle on the NMI
Well that's it *MAS* with a sledgehammer
