While going through a set of disks I recently read, I came across some additional unofficial NEWDOS/80 v2.0 zaps.

They include changing the exit command from EDTASM from a B to a Q, changing the modify cursor in SuperZap to something FAR more friendly, changing the BASIC2 command to LEVEL2, and move.

You can find them on the Unofficial Newdos/80 v2.0 Zap Page.

The site http://inufuto.web.fc2.com/8bit/ had some new (2022) TRS-80 games, but they were all non-working for one reason or another.

Shawn Sijnstra took the time to rework those files so that they will run in a Model I emulator.

You can find them here.

While Frank Durda IV developed his custom aftermarket ROM, XROM, he used the extra space in a 16K ROM to add a diagnostic ROM. That ROM is invisible to the system unless a jumper is used.

A detailed disassembly of the diagnostip portion of the XROM is now available on this sites’ Model 4 ROM Explained – XDROM – Diagnostic Part page.

Frank Durda IV had developed a ROM C which he proposed to have Tandy issue as an update. It added functionality and fixed some bugs. That ROM was not released.

When Frank left Tandy and started M.A.D. sofware, he offered a ROM C replacement for U.S. Model 4’s, called the XROM. Model 4 NGA systems would use this ROM. Other Model 4 systems could use an expanded version called the XDROM, which had some diagnostic code added as well.

A detailed disassembly of that ROM is now available on this sites’ Model 4 ROM Explained- XDROM page.

Tandy Assembly is planning on having their annual get-together on September 29-October 1 of 2023 in Springfield, Ohio.

The NEWPRINT/Multi is now available for purchase from Plaid Vest Software. It is a Virtual Wi-Fi printer with web-browser output for all TRS-80 models. Features Include:

• NEWPRINT/Multi is a Wi-Fi-enabled “virtual” printer adapter that connects to your computer’s printer port and your local Wi-Fi network to send printer output to any device that supports a modern browser (iPad, Desktop PC, Mac, etc.).
• The NEWPRINT web interface can show printer output as plain text, hexadecimal values, Print Shop graphics (Apple II), or Apple IIgs GS/OS graphics printing.
• Text mode output does not (currently) understand special printer control codes used by most word processors (BOLD, multiple font sizes, Form Feed, etc.).
• The NEWPRINT web interface is available from any browser on your local Wi-Fi network at newprint.local
• NEWPRINT uses the standard HTML WebSocket API so you can even write your own web-based or desktop interface for displaying and processing NEWPRINT output.
• Note: A power adapter (+5v DC) and printed User’s Manual are not included to keep prices low. See the PDF User’s Manual below for more information.

Lawrence Kesteloot has updated his TRS80-TOOL to v2.4.1.

The GIT for the source and binaries can be found at https://github.com/lkesteloot/trs80/tree/master/packages/trs80-tool.
