Letter to the room - CompoWellcome about the new firmware TR-DOS v6.05E
4. LETTER TO THE NUMBER
From the Editor: CompoWellcome continues
delight us with their new firmware ROM.
Detours traveled this message
before us. But that is another story ...
(C) CompoWellcome
TR-DOS v6.05E vs TR-DOS v5.13F
or
Everything you wanted to know about the TR-DOS 6.05E,
but were afraid to ask.
In connection with the release of Uzbekistan spektrumistov
(in number of four units) in Fido, it was decided to proudly
announce to the the whole world (Spectrum) that not only
in so far (or close, as anyone)
Russia made new PZU'shechnye gadgets to our computer. What I
wrote earlier about this firmware in Wallpaper'e - full suxx,
because the first count only on the local public and Second was
a long time and is not it :-).
So, we proceed to the consideration and comparison of
various bells and whistles in DOS'ah 05.06 and 5.13.
-= CUT =
For nesveduyuschih: TR-DOS 5.13F - new
:) Firmware DOS'a (and only) with different twists from Russia,
and TR-DOS 6.05E thing local production ;-))).
-= CUT =
Immediately say, that in our firmware
subjected to change not only the DOS, but also
BASIC 128 (instead of 128 Basic'a can use MadRom).
Must first admit that
most of the ideas did not own
production, and are taken from various
DOS'ov. After that, everything was stuffed into
TR-DOS 5.04E (if not mistaken). Yes, and the article used
excerpts:) from the description of DOS'a, for which its author
(DOS and descriptions) thanks a lot!
Item No. 1.
Formatting floppy disks in 3 versions:
ORIGINAL - the usual format;
TURBO - formatting the disk with the other
location of the sectors, which leads to an acceleration of read
/ write drive is approximately 2 times;
FAST-TURBO - formatted similarly
TURBO, but without the test operation (if you
confident in the quality of your floppy disks), while
accelerated by the operation itself formatting.
Turbo format 6.5 DOS'a inferior format DOS'a 5.13, as is
done without bias sectors. Thought about it was, but Because of
extremely rare use of commands TR-DOS 'FORMAT' (mainly for
those purposes the Honey Commander) implemented nebylo.
Bybor format is available on request
DOS after you enter the normal command FORMAT
keys <1> <2> or <3>. Klavisha cancels the command. When
formatting Your Message is issued about the number of formatted
currently tracks and side of the disc.
After the end of the formatting is issued
a request to repeat it.
Item No. 2.
When writing the file to disk in case
file with that name on disk is the DOS prompts to erase the old
file. If You will answer <Enter> or <Y> old file
will be erased and replaced will be recorded
new file if it is not longer than the old one.
If a new file is longer, it will be
recorded as usual with the first free
disk sectors, and will appear in the directory
an erased file. Release a little glyukovato. Gluck climbs at a
record-same file, but with a smaller length. File a written but
the length of the new file will be equal length of the old.
Analogues in TR-DOS 5.13 is not available.
Item number 3.
In the description of the DOS 5.13 write: 'Removed
self-test drive. Drives shall
All 2h80, step 6 ms'. Imho, do so
impossible. Not once have a situation (on different machines)
when the drive has been reset during the first call has
steadfastly refused to Bosko output at zero track. Arises
basically if before kakayanit prog
managed to drive them to the end of the disc.
In DOS'e 5.6 we returned the self test, only
shortened it.
Item No. 4.
Uskorennaya command MOVE. In the usual version of the DOS
MOVE command is the longest on time work, in addition it seems
that the drive is worth more than work. This is because each
times when moving a file is
Read the catalog and write to it. In this
version of reading and writing the catalog are made once.
Directory information is stored in RAM, and all catalog
operations (Only in the team MOVE) produced in
RAM, which speeds up the work of the team, averaging 3 - 4
times, and in some cases and more.
Analogues in TR-DOS 5.13 is not available.
Item number 5.
A new command - rename
Disc: MOVE "name". In this case, the command MOVE
not satisfied, but just the name of the disk is replaced by
"name".
Analogues in TR-DOS 5.13 is not available.
Item Number 6.
In DOS 6.05E changed command editor
line. First, eliminate unpleasant
which occurs at the entrance to the DOS at 128
mode. Second, eliminate the influence of editing keys, which
move cursor to the line in 48 mode. And the most important part
- the possibility of calling previous command by pressing
<EDIT>. If you want to repeat the operation, or repeat it
with a slightly modified parameters, you can call it
immediately after pressing <EDIT>. If you do something typed on
the command line, the key <EDIT> does not work (in the standard
version is invokes the line of BASIC programs).
Analogues in TR-DOS 5.13 is not available.
Item No. 7 (the largest).
DOS 6.05E course supports RAM-disk based on the additional
RAM up to 1024k. In this case 4k away under a directory and
some other features and the remaining free memory allocated by
workspace RAM-disk. To initialize the RAM-disk, use the command
FORMAT "d: name". Next to the D: drive can be
treated as a floppy, with the
only difference is that this disc can not be
change and the power is turned off the information on it is
lost.
Nice feature is that
dumping information on the D: drive is
intact, and possible future work with
them without surgery FORMAT.
For systems programmers, it is important that
work with the RAM-disk does not differ from that of the usual
drive through the input # 3D00, # 3D03, # 3D13, and when you
contact the DOS to routines running at the level of work disk
sector. Program read and write sectors of work even if the D:
drive is not been 'formatted'. User in this
case has all the memory RAM-disk, but without
file organization.
Programs using direct programming K1818VG93 naturally do not
work.
Under the RAM-DISK, by default, is given
not all of 1024K of RAM, but only the older 512K.
Lower 512K set aside for resident (see below). In consequence
of this had to do the ability to read from the port # 7FFD
(hardware, like - see below) to determine the current page of
the lower 512K of RAM.
-= CUT =
I personally use the software definition of the current
page, although of course it can not track the state of the
second screen (as it should?). But this is someone like
more like it.
-= CUT =
Thanks to what is possible from the RAM-DISK'a run not only
the 128K program (eg Land of Myths).
Port of extended memory is used
# 7FFD. If someone wants to can make a
(Installer supplied).
Item number 8 (much less).
Magic'i ... Well what can I say? Entirely
and completely blows from DOS 5.13;).
IMHO, rulnye possible (and I quote an excerpt from the
description 5.13):
"Significantly enhanced features magic knopischi. When
pressed, the complex is suspended and waits:
1 - run the standard procedure of saving, but still there,
and when loading is reduced and adjusted Register R.
2 - the same, but the stack is placed in
bottom of the screen. Designed for burglary.
3 - Go to the STS. BANK = # 57
Two numbers on the stack, and a few bytes
of attributes - depending on the position of the stack. Before
entering the STS is extinguished muzykalka. PC in STS'e shows
the place to stop, but not always. You can find out exactly
under the stack.
4 - Return to the program. Serves as a pause.
In some prog worth checking
address the transition to tyrdose (# 0066), and if
Magik custom, then bummer. In this
versions of such tests do not find differences:
interception carried out at the beginning of zasiraniya
the stack. "
Item number 9.
You have access to all registers of the controller K1818VG93
already in two ways. Pull the from the different versions.
The first method (skorpionovsky):
# 3FF0 OUT (C), A: RET
# 3FF3 IN A, (C): RET
The second (very strange) through new
syscalls # 3D13:
# 0D - Register D contains the lowest address
Port E data register in it. If necessary and chief port
address, it is indicated in register B.
# 0F - Register D contains the lowest address
port, the output of the register data from E
him. If necessary and chief port address, it is indicated in
register B.
And two more (in the appendage):
# 10 - Calling the subroutine entry # 3FBA.
In the HL register address field data, DE
- Waiting time VG93 preparedness.
# 11 - Calling the subroutine reading # 3FD5.
In the HL register address of the buffer time in DE
standby readiness VG93.
Analogues in TR-DOS 5.13 is not available.
Item number 10.
Certainly Fixed bug TR-DOS'a
work with a large group of sectors 5 and 6 teams from # 3D13
(sm.ZF # 3).
Item number 11.
There is a built-in Mini-boot which
run from the TR-DOS command to '8 '(the former team of 80).
Really don `t know who was the author of this rubble, but we
have finished a bit (sorry. ..). Due to the fact that the
switch to drive 'B' can not quickly quickly, it implements
autosearch drives in the drive 'A' and 'B'. For example go to
DOS (disk in the drive 'B') press '8 'and
through two or three seconds boot itself switch to it! And
select the current drive in boot'e possible keys 1-4, and the
key 'D' - Reset Dos.
In DOS 5.12 was there seems to be a small copier, which
judging by the description of version 5.13 thrown ...
Item Number 12.
Similarly, version 5.13 DOS thrown in our memory test, the
filling of which is done via the command PUSH, as a consequence
speed RESET-DOS rose nemeryannom ... A also, through PUSH
cleared memory when resetting of the BASIC 128, with similar
consequences:).
Item No. 13.
Again, as in version 5.13 greatly accelerated reading from
the drive. Much faster to read even a program like iS-DOS and
Honey Comander'e, not to mention programs like Conver Comander,
Real Comander or command TR-DOS LIST etc.
Accelerate the entry, as shown by experiments, unfortunately
not. Some drives do not have time to unwind drive, the
consequences of this horrible ...
Item number 14.
Some minor glyuchki
TR-DOS (which was no longer remember). And just as in DOS 5.13
on a team you can NEW to know the last modified date code.
The so-called 'Rodionovskaya vector
Interrupt # 0900 - # 0A00 'was not affected,
All programs using it are normal.
Additional features
received a small change
BASIC 128 with TR-DOS 6.05E.
Item No. 1.
Naturally maintained by a resident
Honey Commander, but due to change
BASIC 128 get into it with any
reset (other than the 48-th ;-), unlike version 5.13, which
intercepted a resident is possible only when RESET-DOS.
Capabilities resident in our version is much expanded to
intercept discharges can absolutely any program with minimal
memory. Enough to place on at # FFF0 at page 31 (# 1F) line
characters 'Residentpresent!' (No spaces), and immediately
after a reset control will be sent to the address # C000 of the
same page.
Under this resident had already converted:
Real Comander, Conver Comander, FPM (two
version), Luxe Copy, Direct Comander, bo ot Turbinova and boot
Rodionova, STS.
Maybe something else I missed.
Use of such programs has not
an example is more convenient. Additionally, Conver and
Luxe Copy embedded gasilka screen.
Item No. 2.
There is a software RESET-DOS with a choice of any drive, if
reset, hold down 04.01
(1-drive A, 2-B, etc.). Unfortunately
only works on those machines where the keyboard at work dos not
blocked (PROFI, PENTAGON, ATM ...). Also much easier to work
with RAM-DISK'om (not have to write constantly '* "D"' ;-).
Item number 3.
If the screen saver from the BASIC 128 when choosing
item '128 TR-DOS 'press is not just ENTER, and with the
CAPS-SHIFT'om (you can EDIT :-), it automatically when you exit
to DOS from the current drive will be running the file boot.
Just like in Scorpio, only more correct.
Self-a 'Tape Loader' from the screen saver kicked, but worth
'48 TR-DOS '.
Item No. 4.
Pressing 5 + RESET resets the neglect of all residents. Very
rarely happens (when you copy the entire disk for
times) is killed by some residents, so that
after reset comp goes into full meditation, remove it from
which one can only Off.
Of course, many of the items lose their relevance when using
MadRom, but All the same it is not at all, and more
part of the improvements I made when not
suspected the existence of such a thing as
MadRom.
Installer
The installer comes in the form of source code to the Storm.
After compiling it creates a working file for flashing the ROM.
Full delivery firmware must contain the following files:

Port becomes active only in

can. Check for proper assembly of the port
You can check my TEST v4.22.
For a more comfortable working with RAM-DISK'on
I wrote a program from, as in IS-DOS, IMAGE.
It also allows you to save on the RAM-DISK
floppy disk, restore it from disk and
simply copy any disc into memory.
Works, of course, only with TR-DOS
6.05E and RAM-DISK'ami of 512, 384 and
128K. RD at 896K is not supported due to lack meaning.
All the flash and the accompanying software is absolutely
free, you will find they will be able to Station Zero BBS
TashZXNet.
Whereupon, Au revoire!
Editors note: by itself can add that popolzovavshis this
firmware for about six months, we found that this cultural and
rudder fareva! In the version for 512K Ram is a cactus that
RAM-drives from Honey Commandera and DOSa match. That is, there
was as though the IDE. So that this firmware version we are
working its recommendation.
