@zeilemaker54 Do you have perhaps a different version of this kit? Since I can’t find the list you pasted in the one tfh linked to.

No, I think it is the same thing. The information is from a text file on the disk. I do not know the filename by head, but can look tomorrow if you like. I have used information about the kernel changes in my msxsyssrc project to determine the different disk kernels. I have already indetentified 5 versions.

The disk includes a brazilian MSXDOS.SYS and COMMAND.COM. The file with the version history is called SYSFILES.MEM. This is the content:

************************************************************************
Following notes are the changes made to the the MSX-DOS system files.
************************************************************************

COMMAND.COM (version 1.01)

Fixed the problem that file concatenation got "write error"
message and never performed.

October 12, 1984
------------------------------------------------------------------------

COMMAND.COM (version 1.02)

Fixed the problem that command hanged when non-blank separators,
such as commas, semicolons etc., were used for batch command
parameters.

November 14, 1984
------------------------------------------------------------------------

COMMAND.COM (version 1.03)

Fixed the problem that DOS did not reboot after MACRO-80 has
been terminated.

December 15, 1984
------------------------------------------------------------------------

COMMAND.COM (version 1.04)

This version was in-house review only, and was not released.

COMMAND.COM (version 1.05)

Fixed the problem that the cursor was disappeared in some of
the application.
This was because command processor did not care the cursor
status when control was returned from the application. To
fix this problem, it was changed to turn the cursor on just
before passing control to the application.

[NOTE]
Application programs can control the cursor status
by sending following escape sequences to the console.
ESC+"y5" will turn on the cursor, and
ESC+"x5" will turn off the cursor.

The current date displayed by the "DATE" command has been
changed to fit into single line by removing "centuries" of
the year string. The change was made to the Japanese version.
Previously this message had wrapped to the next line, and was
very unreadable.

January 29, 1985
------------------------------------------------------------------------

COMMAND.COM (version 1.06)

Fixed the problem of version 1.05 that the escape sequence
to turn the cursor on was also echoed to the printer.

Fixed the problem of "DIR /P" command that the first file name
was scrolled off the screen when the console width was set
to 30 columns or less. The prompt for the next page was wrapped
to the second line.

Fixed the problem of "DIR" command that columns of the printer
output was not aligned. "DIR" command bypassed output of CR-LF
when the line was automatically wrapped to the next line. When
this was echoed to the printer, consective lines were joined
together.

February 21, 1985
------------------------------------------------------------------------

COMMAND.COM (version 1.07)

Accepts codes 80h to FEh as file name characters from this
version. They are Hiragana and Katakana characters in Japanese
version.

Fixed the problem of "DIR /W" command of version 1.05 that
the tab position was not aligned for the first line. Escape
sequences to turn on/off the cursor was also counted for tab
position management.

February 28, 1985
------------------------------------------------------------------------

MSXDOS.SYS (version 1.01)

The disk error handling procedure was improved.

There was a danger that a disk being damaged, if, the disk
was a non-MSX-DOS format (such as CP/M), an disk error occurred
and "Ignore" was selected.

To handle this case, changes have been made to the MSXDOS.SYS
to display "Unsupported media type" and "Abort" the process,
If disk driver detects illegal format.

March 7, 1985
------------------------------------------------------------------------

COMMAND.COM (version 1.08)

Fixed the problem of COPY command that "Write error" was
displayed while copying multiple files. The copy had been
aborted in the middle.

March 24, 1985
------------------------------------------------------------------------

COMMAND.COM (version 1.09)

Fixed the COPY command problem that when you try;

COPY A:TEST A:TEST

old COMMAND.COM read that file and wrote the file into same
disk. This should have been detected as

File cannot be copied onto itself
0 files copied

April 30, 1985
------------------------------------------------------------------------

MSXDOS.SYS (version 1.02)

Fixed the problem that disk error handler ran away when long
batch command was entered.

When invoking batch, if the batch parameter was very long (about
70 bytes), it destroyed MSXDOS disk error handler code. There
was not enough space for batch parameters.

New version will allow batch parameters even if they fill up
entire command line.

COMMAND.COM (version 1.10)

Added support for 80 columns display of MSX2.

"MODE" command parameter now allows up to 80 columns.

Fixed the problem of copying files onto itself finally.

Version 1.09 of command still could not detect the
cases like:

COPY *.*

and files were read in and written back in the same
place and sometimes got truncated.

Fixed the problem when appending binary files.

In the version 1.09 of command, appending binary files,
sometimes got incorrect data in ABC.BIN, and sometimes
got "Insufficient disk space" error message.

This problem was hidden until version 1.09 began to
handle append properly. Previous versions never did
"append".

Fixed the problem when concatenating ASCII files.

In ASCII mode copy, there were cases that source file
was not cut off at first control-Z. This occurred
when the file size was multiple of 256.

There may be no problem for copying single files, but
when the files were concatenated, this would cause
unwanted end-of-file and rest of the data after
control-Z would not read.

Fixed the problem when copying null file.

In the previous version of command, when the source
file was size was 0, destination file was not written,
though there appeared the message that file was copied.

Fixed the problem of batch files with very long line.

While processing batch, there were chances that the
command line exceeded internal buffer (after parameter
substitution, or batch file itself had longe lines)
and destroy other internal work areas.

New version will check the size of the command line
and ignore excessive characters.

[KNOWN BUGS]
If the command line with many many parameters was
entered to invoke batch file, say, full of separators
with many many "null" parameters, it will still destroy
MSXDOS.

Version 1.10 assumes MSXDOS.SYS version 1.02 or later,
and uses up all the spaces for batch parameters. When
combined with version 1.00 or 1.01 of MSXDOS.SYS, it
cause system crush, by executing BATCH command.

July 21, 1985
------------------------------------------------------------------------

MSXDOS.SYS (version 1.03)

when printer does not exist and control-P is pressed, system
hangs waiting for printer ready.

Only control-stop can force BIOS to exit printer wait loop.
But any characters including control-N are thrown away while
control-STOP is depressed, and trying to echo "^C", DOS enters
wait loop again. This is a ROM BIOS problem.

This fix trys to cover this situation; this will wait enough
time for auto-repeat to occur and then echo "^C".

Recovery action should be:

(a) Hold down [CTRL] and [N].
(b) Press [STOP].
(c) Still holding [CTRL] and [N], release [STOP].

COMMAND.COM (version 1.11)

Fixed the bug of version 1.10 that it forgets to load the latter
half of the *.COM file when the file size is lager than 22k
bytes. Nothing was loaded after address 58FFH.

Fixed the bug, known in version 1.10, that caused system crash
when there were many many batch parameters. And fixed the
incompatibility of version 1.10 with the old version of
MSXDOS.SYS (1.00 or 1.01).

[NOTE]
This is a summary of system crash possibility when
the batch command is entered. number(s) in parenthesis
are;

1. When the command line is longer than 70 bytes.
2. When the line in batch file is longer than 128 bytes.
3. When number of batch parameters is more than 64.

MSXDOS.SYS

1.00 or 1.01 1.02 or later
+---------------+---------------+
1.00 to 1.09 | maybe (1,2,3) | maybe (2,3) |
+---------------+---------------+
COMMAND.COM 1.10 | always | maybe (3) |
+---------------+---------------+
1.11 or later | maybe (1) | never |
+---------------+---------------+

Changed the message timing when multiple files are copied.

When dual drive simulator is active, commands like;

A>COPY *.* B:

displayed message sequences like;

FOO1 DAT (FOO1.DAT was found)
FOO2 DAT (FOO2.DAT was found)
Insert diskette for drive B:
and strike a key when ready
FOO3 DAT (FOO3.DAT was found?)
Insert diskette for drive A:
and strike a key when ready
FOO4 DAT (FOO4.DAT was found)

It looked as if FOO3.DAT was found while drive B
diskette was inserted. Though this was not true, there
was some uneasiness in this sequence.

Aug 23, 1985
------------------------------------------------------------------------

COMMAND.COM (version 1.11)

Fixed the bug of version 1.10 that file(s) get mixed up when
other files are appended to it by "COPY" command with a
(default) switch "/A". Append was successful, but original data
was lost.

[NOTE]
To fix above problem, shipment of August 23 version has been stopped
in the middle.

Yes. That file is also on the disk I linked to earlier.
Quite some nasty bugs in the older MSX-DOS versions.
