TRSTools Version 1.06

mkr — Tue, 28 Jun 2011 11:37:59 +0000

This release contains bug fixes and several new features:

A faulty format detection routine that was rejecting many NEWDOS/80 disks is now fixed (thanks to Ira Goldklang).
TRSTools now offers read-only support for the most common Montezuma Micro and LNW80 CP/M formats.
TRSTools now offers read-only support for Color Computer RSDOS disks.
The file properties and disk properties dialog boxes now only show information pertaining to the file system.
TRSREAD and TRSWRITE were also updated with these changes to version 4.29.

The new version can be downloaded here: TRSTools version 1.06.

TRS32 Version 1.26

mkr — Mon, 27 Jun 2011 11:53:08 +0000

This release contains two bug fixes:

On some Windows 7 systems, a synchronization conflict led to sluggish responses by the user interface. This problem has now been fixed.
Keyboard handling is now improved to make certain SHIFT+CLEAR key combinations more consistent (suggested by Darryl Grainger).

The new version can be downloaded here: TRS32 version 1.26.

TRSTools Version 1.05

mkr — Wed, 01 Jun 2011 14:18:56 +0000

This release contains a number of fixes and improvements:

TRSTools now extends LDOS and LS-DOS file dating to the year 2012 and beyond. New file dates can now range from 1980 to 2079 but are stored in a way that is completely backward compatible with older disks. See LDOS and LS-DOS: 2012 and Beyond – A Solution for more information.
TRSTools will now prompt to apply post-2011 date extension patches to any non-write protected Model 4 LS-DOS 6.3.1 or Model I and III LDOS 5.3.1 disk image. (This prompt can be turned off in the Preferences menu.) It will automatically select the correct patches based on the disk type.
I added improved recognition of all three MULTIDOS date formats. TRSTools will now automatically recognize which format is being used by the directory.
I fixed a problem with reading Model III TRSDOS files. Under a few circumstances, reading from a heavily fragmented Model III TRSDOS file could result in corrupted data.
An option in the file viewer to switch to a hexadecimal view wasn’t always present. I have fixed that omission.
TRSREAD and TRSWRITE were also updated with these changes to version 4.28

The new version can be downloaded here: TRSTools version 1.05.

TRS32 Version 1.25

mkr — Wed, 13 Oct 2010 12:50:07 +0000

This release includes two bug fixes and one new feature:

William Bosacker sent me a NEWDOS/80 boot disk that kept generating “Device not available” errors instead of displaying a directory. I tracked the problem down to a one bit error in the emulated interrupt status ports. This qualifies as one of the most obscure emulation bugs I have ever found; it would occur only one time when reading that one port at that one instant.
Ira Goldklang sent me a Model III boot disk that was being identified as Model 4 by the “Autostart” feature. Although the disk still worked (it just ran in Model III mode), I added recognition of this unusual boot sector to the autostart routine.
I also added a new feature suggested by Ira Goldklang. Now hovering the mouse cursor over the floppy drive indicator light in the status bar will display the current drive status and position. This makes it easier to determine if a boot disk is loading or just cycling endlessly.

The new version can be downloaded here: TRS32 version 1.25.

TRSTools Version 1.04

mkr — Thu, 30 Sep 2010 10:45:40 +0000

Improved viewing of MULTIDOS BASIC programs
Improved recognition of DOSPLUS and NEWDOS/80 disks (thanks to Ira Goldklang and William Bosacker)
TRSREAD and TRSWRITE were also updated with these changes to version 4.27

TRS32 Version 1.24

mkr — Wed, 23 Jun 2010 09:58:09 +0000

Eliminated “Parity error during read” errors sometimes generated by NEWDOS/80 while formatting double-sided virtual disks (thanks to Pascal Holdry)
Corrected behavior when pasting TAB characters (suggested by David Alexander)

TRSTools Version 1.03

mkr — Wed, 28 Apr 2010 09:06:51 +0000

Improved Windows 7 support in several areas (thanks to David Sutherland)
Improved viewing CMD files on MULTIDOS disks
Eliminated extraneous beep when viewing files under certain sound schemes

TRSTools Version 1.02

mkr — Wed, 31 Mar 2010 08:22:53 +0000

Greatly improved the recognition of some marginal disk formats
Added a new Z80 disassembly viewer as the default for CMD files
Added the ability to switch between different file viewers
Fixed the incorrect window sizes with larger DPI values (thanks to David Sutherland)
Fixed the problem encountered when viewing blank binary files (thanks to David Sutherland)

Z80Disasm Version 1.00

mkr — Tue, 23 Mar 2010 22:15:03 +0000

Z80Disasm, a freeware command line Z80 disassembler for Windows, is released. Z80Disasm is a symbolic labeling disassembler that supports all Z80 instructions and can read either TRS-80 CMD files or Intel HEX files.

TRSREAD and TRSWRITE Version 4.26

mkr — Tue, 02 Mar 2010 20:21:08 +0000

TRSREAD and TRSWRITE, command line TRS-80 disk image manipulation tools for Windows, are released. TRSREAD and TRSWRITE allow you to manipulate TRS-80 disk images in a similar way to TRSTools, only on the command line.
