Irwin has written two DiskDisk related programs. He writes:
CDD/CMD v2.0.0 is a little utilty to use with the DiskDisk utility from MISOSYS that allows us to emulate the MS-DOS CD command. I wanted to be able to change DiskDisks as easy as I change subdirectories on MS-DOS.
Usage: CDD [:dn] DDfilespec
Where DDfilespec is the name of the DiskDISK file you want to mount. and :dn is an optional drive number you want to use for that file. The default is :4.
RMD/CMD v2.0.0 allows for the DISABLE to disable not just a DiskDISK mounted at :4, but the user is now free to disable a DiskDISK no matter which drive it is mounted to.
Usage: RMD [:dn]

(Irwin-B-Burton).gif)
Irwin Burton has written two new TRS-80 Model III programs - NAMEIT and PWD. NameIt allows for all characters to be in a LDOS disk label and PWD (like the unix command) will give you a quick update of what disk is mounted in a drive number. Source is included.
KiwiSinceBirth has posted updates to his compilable source file for the Model I/III ROM
He has a traditional Model I Level 2 BASIC ROM and Model III Level 2 BASIC ROM which have comments and which can be compiled into a workable ROM. His source differs from a standard disassembly in the following ways
These ROMs can also be somewhat customized as follows:
| #DEFINE VER12 | uncomment this to degrade from V1.3 to V1.2 of the ROM. |
| #DEFINE VER13 | this is the default if VER12 is not defined, and doesnt need to be uncommented |
| #DEFINE EACA80 | uncomment to enable Dick Smith System-80 (EACA) hardware support. NOTE: While not mandatory you should also define VER12 since the System-80 ROM was based on V1.2. V1.3 has not been formally tested, but assume should work, and opens ability to also specify FREHDBT. This only targets the core 12kb ROM, and does not include the latter Rom extensions |
| #DEFINE FREHDBT | Enables the FreHD auto boot feature, i.e. the Auto boot ROM. This requires version 1.3 ROM as a base, please do NOT define VER12 as it is not compatible (it will be ignored anyway) Consider also enabling NMIHARD to ensure reset (on non-floppy machine) will force a reset. |
| #DEFINE NMIHARD | Set NMI (reset) as always perform a hard reset. Normally on non-floppy systems NMI performs a soft reset returning to the READY> prompt with the basic program intact. This is useful in system without floppy disk to force a full reset (0066h) |
| #DEFINE LOWCASE | Disable Alpha character translation of letters A-Z,a-z to the values on range 00h to 1Fh. This is useful when a lower case mod is installed, but an alternate video driver has not been installed, or where the font rom on the machine has the alternate characters in the 00h 1Fh range (0471h) |
| #DEFINE FASTMEM | Speed up startup memory size check by checking first byte of every 256 page, rather than every byte. |
| #DEFINE BUGFIX5 | Fix Error 5 - 08A7H - INT(DoubleValue) rounding |
| #DEFINE BUGFIX8 | Fix Error 8 - 1009H - PRINT USING, - sign at end of field |
| #DEFINE PATCH | Includes NMIHARD, LOWCASE, FASTMEM, BUGFIX5, and BUGFIX8` |
| #DEFINE SIZE16K | Will pad the end of the rom with $FF to 16KB size. useful if want to append multiple ROM images for used in large 16K paged rom |
| #DEFINE _EMBED | Strip all HW, and IO routines leaving just BASIC language as standalone code and used in L2 Basic for CP/M |
He has also developed an enhanced ROM for both machines which have slightly broken compatibility, but which otherwise include new support, features, and some bug fixes
| #DEFINE NEWBOOT | Enables a new boot routine which asks for "diskette?" when no disk is detected and retries. It also allows for break to be pressed at any time. (Credit : John Swiderski) |
| #DEFINE FREHDBT | Enables the FreHD auto boot feature, i.e. the Auto boot ROM. This requires version 1.3 ROM as a base, please do NOT define VER12 as it is not compatible (it will be ignored anyway) Consider also enabling NMIHARD to ensure reset (on non-floppy machine) will force a reset. |
| #DEFINE NOMEMSIZE | Skip user input of Memory Size? override at startup with M key. (Credit : John Swiderski) |
| #DEFINE FASTMEM | Speed up startup memory size check by checking first byte of every 256 page, rather than every byte. |
| #DEFINE NMIHARD | Set NMI (reset) as always perform a hard reset. Normally on non-floppy systems NMI performs a soft reset returning to the READY> prompt with the basic program intact. This is useful in system without floppy disk to force a full reset (0066h) |
| #DEFINE LOWCASE | Disable Alpha character translation of letters A-Z,a-z to the values on range 00h to 1Fh. This is useful when a lower case mod is installed, but an alternate video driver has not been installed, or where the font rom on the machine has the alternate characters in the 00h 1Fh range (0471h) |
| #DEFINE MSGSTART | Enhanced startup message showing Free Bytes available to BASIC |
| #DEFINE KEYBOUNCE | Enables the Keyboard debounce routines that where introduced in rev1.3 |
| #DEFINE BUGFIX1 | Fix Error 1 - 04F6H - 32 Character Mode Line Length |
| #DEFINE BUGFIX2 | Fix Error 2 - 153EH - Random Number Single Precision Overrun |
| #DEFINE BUGFIX5 | Fix Error 5 - 08A7H - INT(DoubleValue) rounding |
| #DEFINE BUGFIX7 | Fix Error 7 - 0EF2H - Space after type declaration tag |
| #DEFINE BUGFIX7C | Fix Error 7C - 213DH - Space after TAB token |
| #DEFINE BUGFIX8 | Fix Error 8 - 1009H - PRINT USING, - sign at end of field |
| #DEFINE BUGFIX11 | Fix Error 11 - 2301H - Overflow on Integer FOR loop |
| #DEFINE BUGFIX13 | Fix Error 13 - 1222H - Display of Single Precision Numbers |
| #DEFINE EACA80 | (OPTIONAL) uncomment to enable Dick Smith System-80 (EACA) hardware support. This only targets the core 12kb ROM, and does not include the latter Rom extensions |
| #DEFINE SIZE16K | (OPTIONAL) Will pad the end of the rom with $FF to 16KB size. useful if want to append multiple ROM images for used in large 16K paged rom |
To make room for all this, cassette support has been removed.
Additionally, you can now download pre-built binary images for most common configurations. There are 16 variants. Hr did this to make it easier to use, no assembly required, no defines to understand, just choose the ROM that makes sense. It also means the vanilla configurations can be compared against official roms, to check for binary compatibility. This build process is automated by GITHub anytime a change is made, it will assemble and publish a new release.

To make linking easier, I have added clipboard icons to the Hardware, Software, and Service Manual pages.
The SSL certificate for www.trs-80.org has been purchased and applied, so related security warnings should have stopped.
NEWDOS/80 v2.0 for the Model I has been disassembled, with most of the heavy lifting done by Claude AI, with help from Gemini and Grok. They all definitely have their strengths and weakenesses.
The main page can be found here.
I have also created a main-menu entry for all disassemblies, to make them easier to get to. That can be found on the navbar, or here.

If you sent in a disk request which was not processed, you have my apologies. As part of the site redesign, I seem to have dropped the perl script which actually sent the disk request form in! If you emailed me, it was processed; but if you silently sent in the form and that's it ... it wasn't. I have fixed the form so it should submit. If you requested disks and did not get them, please fill out the form again.

I wanted to make it easier for people to be able to refer to specific portions of the site, so I have added CSS and Javascript that will put a little clipboard up on headers. If you click the clipboard, the URL for that specific header will be copied to your clipboard. Thank you Gemini for the code!

Amardeep Chana has written up step-by-step instructions to modify a Model I to run much cooler and more reliably. It involves modifying the system to no longer need the +/-12V to power the RAM, focusing solely on 5V.
You can download the step-by-step guide here.
The Easter Egg page page has been updated with a reverse engineering of Randy Cook's secret screen from TRSDOS v2.x. Thanks to George Philips and absolutely no thanks to Gemini who halucinated an elaborate routine that didn't exist!
Thank you to everyone that has been reporting in with questions and issues!
And special thanks to Ven Reddy who pointed out that when I moved off of WordPress I lost the Site Search function. I personally consider the site too unwieldy and too hard to find anything, and I wrote it - so I can imagine what everyone else goes through. So the loss of site search was a big loss. The site search page is now present on the navbar but can be found here as well.
If anyone has any better ideas as to how to organize the navigation or make it easier to find subpages and content, please let me know.
In other updates, I have been working on the disassembly pages trying to add more information to the input/output portions. Right now it's in the form of adding bit tables to show all the options and explanations within each comment. Also, as of last night, the disassemblies are "mobile friendly".
