NEWS:
=====

Dragon 32/64
------------
1) Tom Erik Gundersen (a regular in our live chat) posted a photo of the
manual and hardware for the DriveWire Microserver, a self-contained (no
separate computer required) micro SD card DriveWire server for the Dragon,
which also included a custom ROM (see photo in comments):
https://www.facebook.com/groups/dragon32/posts/4469497403309894/

2) I don’t know if this was covered on last weeks show (it was posted a
few hours before show start), but Julian Brown posted his 4th VLOG about
his VDG/SAM replacement upgrade board:
https://www.facebook.com/groups/dragon32/posts/4468617740064527/

3) Roy Berridge has a bit of a video problem on his Dragon 32. Dragon
tamers needed!
https://www.facebook.com/groups/dragon32/permalink/4469067310019570/

Coco 1/2/3 (and multi-platform)
-------------------------------
1) TRS-80 Retro Programing on YouTube uploaded an update/progress video
on his port of the Atari 2600 Haunted House game to the Coco:
https://youtu.be/SDuI7Azc-QQ?si=bzJ6JPVZIZRBfrCX

2) Brian Palmer typed in and uploaded a DSK image and a screenshot of the
Sydney Opera, originally done by Bill Baldacchino in Austrailia. I think
this is a Coco 3 640x192x4 screen?:
Screenshot:
https://www.facebook.com/groups/2359462640/posts/10164543537102641/
DSK image on the Coco Facebook group:
https://www.facebook.com/groups/2359462640/posts/10164543540617641/

3) Rich Stephens posted a photo showing his Coco 3 running the Fujinet
cartridge bus prototype (and linked to the XRoar emulator and Fujinet Go
Android with XRoar as well):
https://www.facebook.com/groups/2359462640/posts/10164514197557641/

4) Erico Patricio Monteiro posted an animated GIF showing his Coco 1&2
rendition of RoboCop walking, which looks better than the Coco 3 official
port:
https://www.facebook.com/groups/2359462640/posts/10164522761537641/

5) Bradley Goldsmith teased out a picture of a Coco hardware cartridge
that he is working on in the Coco Facebook group:
https://www.facebook.com/groups/2359462640/posts/10164535086752641/

6) Cedric Beaudoin announced last week that the second batch of the ESP32-Coco
have all been produced and shipped. He also notes in the comments that he
is not planning on doing a 3rd run until maybe this fall:
https://www.facebook.com/groups/4262638377332924/posts/4388957741367653/

7) Tristan Robichaud has released the first draft of EPS32-Coco base
documentation. He would like some feedback, as well as checking for
factual errors:

8) Edgar Pinheiro posted on the Clube Color Brasil Facebook page that he
is selling his multi-pack boards, along with a photo:
https://www.facebook.com/groups/397401583720895/?multi_permalinks=26989110334123325&hoisted_section_header_type=recently_seen
Video of it in action:
https://www.facebook.com/edgar.pinheiro.14/videos/2494957724359933/

9) Michael Pittsley started an interesting discussion in the Coco Facebook
group, asking that since many people have now gotten hardware and software
for the Coco that they couldn’t afford when young but now have; do people
use the Coco in modern times for more than just games, and if so, for what?
https://www.facebook.com/groups/2359462640/posts/10164536348097641/

10) Allen Huffman did a post about the 1995 Coco 3 dual direction hardware
scrolling 16 color graphic screen demo that Sock Master (John Kowalski) did,
as he did not recall seeing it at the time of release (it originally came
it on Frank Swygert’s World of 68 Micros magazine). This is pure BASIC;
no assembly language routines at all:
https://subethasoftware.com/2026/07/14/sockmasters-2-way-scrolling-in-basic/

11) Coco Town returns with a deep dive on how BASIC handles the keyboard,
and even how the Dragon ROM’s improved on the Coco version:
https://youtu.be/tzZRDFCFvxA?si=rzkYfPgWd_HOG4ff

12) Lee Perkins has released several videos showing different aspects of
his port of Montezuma’s Revenge to the Coco 3. I don’t believe that
this game has been released yet:
Partial play:
https://youtu.be/aNmtxytdnCg?si=XRXHS6a-AvLCnY7s
Ways to die (including different animation sequences depending on which way):
https://youtu.be/vMKxcKBMYuE?si=lkx_nd_K6is545CC
High score board:
https://youtu.be/7NQetaGIBNo?si=UM3LZa9btxXCx6Af

13) Pierre Sarrazin has released version 1.99 of CMOC, which has the
following updates:
- fixes buggy optimization
- inline assembly now support referring to offses of struct members
- Added several non-void-function
- minor optimizations
http://gvlsywt.cluster051.hosting.ovh.net/dev/cmoc.html
I also didn’t realize that Pierre had also released his own PMODE
4 artifacting game (written in CMOC, naturally) of Astrosmash, called
CocoSmash, which needs a 64K Coco or higher Coco 1,2,3 to run:
http://gvlsywt.cluster051.hosting.ovh.net/dev/cocosmash.html

14) Some sad news passed on by Tim Lindner – Art Flexser (author of ADOS
& ADOS-3 amongst many other things) has passed away. He was active on the
Cocolist for decades:
https://goldsteinfuneralchapel.com/tribute/details/772

15) Dennis Page wants to know what roms work on a CoCo1 with 64K?
https://www.facebook.com/groups/2359462640/permalink/10164535715032641/

MC-10
-----
1) Scott Gilson is looking into starting manufacturing of the MCX32-SD again,
since they very rarely come out anymore from zippsterzone.com. If you are
interested in one (or more), let him know on his Facebook MC-10 group post:
https://www.facebook.com/groups/731424100317748/posts/27336350052731791/

2) Allen Huffman did his first MC-10 blog post on his Sub-Etha Software
site. In this entry he covers Jim Gerrie’s reverse (invert) print routine
in detail including the assembly source that makes it happen:

3) YouTube channel Freerolls Club has released several gameplay videos of
older games that Jim Gerrie had ported to the MC-10 (from 1971-1974). The
poster mention that “This is a gmae with an AI component modified to work
on the TRS-80 Micro Color Computer (“MC-10”) using Micro Color BASIC
from the author’s published source code”. I am not sure what this means?
Games include: Gomoku, “The other Star Trek game”, Oregon Trail,
Hangman, Composer, Hamurabi, Caves1, Lemonade Stand, Hunt the Wumpus
https://www.youtube.com/@freerollsclub/videos

Game On news (all Coco related platforms):

4) Alex Gayer posted a DSK image of a Battlship clone for 32K Extended
BASIC Coco’s to the Coco Facebook group; a work in progress but playable:
https://www.facebook.com/groups/2359462640/posts/10164516614222641/
He earlier posted a screenshot of it running in emulation along with a
quick IDE preprocessor he “whipped up”:
https://www.facebook.com/groups/2359462640/posts/10164516415007641/

5) Dr. Boisy Pitre posted a link to Rich Lucente’s first public release of
his native Z-Machine interpreter for NitrOS9 (and compatible with Version 3
story files). This is the Infocom engine written in OS9 Assembly language,
which will allow all of the classic Infocom text adventures to run under
OS-9/NitrOS9:
https://www.facebook.com/groups/2359462640/posts/10164528820297641/

Coco 1/2/3 (and multi-platform)
-------------------------------
1) Glen Hewlett has released several updates to his BASIC to 6809 compiler:
Version 5.29:
V 5.29
• The CoCo 1/2 graphics mode was reserving an extra graphics page
beyond what the user requested, wasting upto 6144 bytes of RAM
• Fixed a bug with CASE ELSE when used inside an IF/THEN/ELSE statement
• Fixed a problem with the TRIM commands that could corrupt the
stack if given a string with a size of 0
Also the compiler can now playback movies from the CoCoSDC on a CoCo 1/2,
in GMODE 8,15 & 16. The MakeNTM program has been upgraded to create the
movies in the new CoCo 1 modes.
V 5.30
• Made the CoCo 1/2 Movie player use less RAM and it's own RAM for
the Audio buffer, as it was previously using some test RAM that could
have been user code and also previously also required the Math_Integer32
library.
V 5.31
• Fixed LOADM command so it works properly on real hardware
(initialized directory and other disk bytes)
• LOADM now will add ".BIN" to a filename if it's missing
• SDC_LOADM now will add ".BIN" to a filename if it's missing
https://github.com/nowhereman999/BASIC-To-6809

NEWS:
=====

Dragon 32/64
------------
1) Julian Brown has posted update 3 video blog about his Super SAM/VDG
board update, this time covering sprites:
https://youtu.be/IMoklF2iiq4?si=1U-ih6caFOy3eEj8

Coco 1/2/3 (and multi-platform)
-------------------------------
1) Grant Bloedow posted a YouTube short showing his beta of a server
based implementation of the XRoar emulator with a fujinet server (using
the Becker port). It also adapts to a web interface and can run on phones,etc.
https://youtube.com/shorts/nFmITESf9io?si=ksIXTl_n1T5S7v2n

2) Allen Huffman put up a blog post explaining some of the quirky behaviour
of the PPOINT command in Extended Color BASIC, depending on PMODE and
SCREEN settings:
https://subethasoftware.com/2026/06/23/what-you-pset-is-not-always-what-you-ppoint/

3) Keith Frechette has started a project called “Li’l Commander” based
on Robert Kilgus’ Color TRSDOS that came with EDTASM+. This is a set of
routines to make file handling much easier than doing straight Disk ROM
calls, and I think Brian Wieseler actually has a more modern version that
Robert did back in the day. The new program by Keith is callable by the
DOS command, and he mentions in his Facebook post that he has more planned:
https://www.facebook.com/groups/2359462640/posts/10164438485797641/

4) Robert Sitton has released video of his BOING.DSK challenge, which
shows ray tracing to do the “warp bubble” effect on a graphic image
on the Coco. In the comments he has video of an optimized, faster version
that does 3 such bubbles at once:
https://www.facebook.com/groups/2359462640/posts/10164438315277641/

5) Reinaldo Torres has announced his TTGO-VGA32-COCO, which is an emulator
that uses that quite cheap LilyGO TTGO VGA32 board. From his post on the
Coco Discord:
“After several months of hard work, I am happy to finally share my latest
project with you all! Say hello to TTGO-VGA32-COCO, an emulator built to
bring the legendary Tandy Color Computer experience to ultra-affordable
hardware. If you have a LilyGO TTGO VGA32 board lying around (or are
looking for a great reason to buy one for just a few bucks), this project
turns it into a self-contained CoCo powerhouse! Some of the key features:
- Single Unified Firmware: No need to flash different files for different
setups. One firmware handles everything.
- Online Switching: Seamlessly toggle dynamically between a CoCo 2 and
CoCo 3 environment right from the interface.
- Fully Embedded & Standalone: Runs entirely on the cheap LilyGO board. All
you need to get started is a standard PS/2 keyboard, a PS/2 mouse, and
an SD card loaded with your favorite software.
I’ve put a lot of long nights into tweaking this to get it running
smoothly, and I would love for you guys to flash it, play around with it,
and let me know what you think!”
Github link:
https://github.com/reyco2000/TTGO-VGA32-COCO

6) Thomas Cherryhomes posted where to get the test builds of Fujinet &
emulator combo downloads for Android that can run Atari 8 bit, Apple II,
Adam, MSX, and of course the Coco:
https://www.facebook.com/groups/2359462640/posts/10164437237882641/

Main article:
https://www.phoronix.com/news/BASIC09-LLVM-Front-End
NOTE: there are some videos of programs written this way in the basic09
channel on Discord from Boisy himself that can be shown.

8) Rich Stephens posted that a new update to the Fujinet News app for the
Coco is out with more enhancements:
- Highlighted text improved
- consolidation of redundant code
- Added ability to toggle through color sets in both high res and 40/80
column Coco 3 modes
- Selected screen width/height & color set saved in an app keyboard
- Disk image now auto-boots news
Facebook post and demo video:
https://www.facebook.com/groups/2359462640/posts/10164449633802641/

9) For those who have followed Don Sorensen repainting his Coco’s and
coming very close to the original colors, he has posted the exact car
equivalent paints he has used:
https://www.facebook.com/groups/2359462640/posts/10164446599402641/

13) Tech X Docs channel on YouTube released a video “Remember These
Embarrassing 1980s Tech Products?”. For some reason he lists the Coco
3 as one of them:
https://www.youtube.com/watch?v=YwiinYBq6Ns&t=1209s

14) TRS-80 Retro Programing posted a video this week showing his start of
