Special NOTES:

For those who want to try an online BBS running on a real 512K Coco
3, you can reach Terry Trapp’s RiBBS system here (please note that
this an active development machine so the BBS occasionally goes down
when Terry is working on hardware, etc).:

VCF-Midwest (the largest retro show in North America, I believe) is
September 13-14 at the Schaumburg Convention Center in Schaumburg,
Illinois. This year is the 20th anniversary of this show, and there is
a lot of collaboration between CocoFest and VCF-MW, so expect a large
number of Coco and Glenside people at the show! Still free admission,

the Connecticut Convention Center in Hartford, Connecticut. Tickets

Dragon 32/64
------------
1) RetroFest 2025 was held in Swindon, UK last weekend, and included
some Dragon setups. Various people have posted videos and photos from
the show:
(show folder of some pics Richard Harding forwarded me)
Richard Harding's photos posted on Facebook:
https://www.facebook.com/groups/dragon32/posts/4049278535331785/
Chris Poacher's Powerpoint presentation about Microdeal (over 17
minutes):
https://www.facebook.com/groups/204334613785733/posts/1699214204297759/
He also made a 30 second video video (there is another
video in the comments showing when it got much busier):
https://www.facebook.com/groups/204334613785733/permalink/1696530531232793/?mibextid=K35XfP&rdid=8dXxvMzP2ihaAN2B&share_url=https%3A%2F%2Fwww.facebook.com%2Fshare%2Fv%2F1Bz45E3Ma8%2F%3Fmibextid%3DK35XfP
YouTube channel "More Fun Fixing It" did a 1+ hour video about the
whole show in general:

2) Julian Brown posted a summary update on his Dragon ATX project
to the World of Dragon forums. He mentions that the ATX machine is
running and everything except the cartridge port, real time clock and
expanded audio built and working. He then goes through updated boards,
etc. and the status of each:
https://archive.worldofdragon.org/phpBB3/viewtopic.php?f=9&t=11282
He also posted an "inbetween" version of his CPLD based VDG replacement
board, which will handle things like switching between PAL and NTSC:
https://www.facebook.com/groups/dragon32/posts/4053734601552845/
3) John Whitworth announced that he has SuperRGB boards available
via eBay and his website. Based on Phil Harvey-Smiths's original
DragonRGB board, it outputs clear RGB for both Dragons and Coco 1/2's,
and plugs sraight into the VDG socket. Works with the T1 variant too:
https://www.ebay.co.uk/itm/236131257361

He also has the extender cable available (this allows extending a 40
pin socket to move such a chip out of the way of upgrades, etc.):

4) Reselling Ashley on YouTube showed a "rare Dragon 32 console bundle"
(not working) that he got at a garage sale style event in the town
of Bridlington. He is a reseller (flipper), so he sold it, but it
came with a box of stuff as well:

Coco 1/2/3 (and multi-platform)
-------------------------------
1) Glen Hewlett has announced that Version 4.40 (and then 4.41) of
his BASIC-TO-6809 cross compiler. The biggest change this week? It
now supports code output for Dragon 32/64, including proper keyboard
mappings. There are also minor bugfixes and crunching of the INKEY
and INPUT routines to save about 300 bytes:
https://github.com/nowhereman999/BASIC-To-6809
2) Not to be outdone, the cross-compiler for many 8 bit targets,
ugBASIC, had an update to it's main branch , mostly bug fixes but
also adding support for string constants in DATA statements using
square brackets:
https://ugbasic.iwashere.eu/changelog/main
3) Juan Castro has been working on additions to HDB-DOS for the Coco
1/2's to add extra functionality, and has been posting updates to
the Coco listserv mailing list. Some things that he has added:
ON ERROR GOTO
Drop box download link for the disk image to try (note that there are
over a dozen builds for different hardware configurations). This is
the same project we mentioned a few weeks ago where he has all Coco
3 tokens now recognized (so programs can load without errors), but
some commands are re-purposed. Things like 51x24 and 64x24 screens on
PMODE 4 that are set with the WIDTH command, and LOCATE works on them;
LPEEK and LPOKE (which originally allowed those commands to work on
the entire 512K RAM of a Coco 3) now allow 16 bit values as an example
(show readme from link below for some details):
https://www.dropbox.com/scl/fo/9p5ydq5hqgp4b1fbqyyif/AKnngotPgk1PLUm6kw0nn5U?rlkey=pxtfum7dzwno0ej42bfb8ucrb&st=duyykgkj&dl=0
4) It was pointed out on the Coco Discord that a blog website is
up called "Tandy TRS-80", which features some Coco related material
(the last 4 entries up to May 18 are Coco related, with the May 15
& May 18 entries are about adding cooling to a TDP-100 case/Coco
"F" board computer combination). I don't think that I have covered
it before, but it's been around since March 2024 (there are some
formatting issues, at least for me, on the main home page):
https://tandy-trs80.com/cool-my-coco/
5) Pierre Sarrazin, hot off of a CMOC update last week, has now
added a new library as well called WydeAlloc. This offers dynamic
memory allocation suitable for a 16 bit platform, and can implement
C functions like malloc() and free(). It is distributed uner GNU GPL
version 3 or later. I think this is for CMOC itself to use?:

6) Simon Jonassen put up another sample of his
wobblemode/semigraphics-24 picture renderings - from his comments,
the best one he has managed yet:
https://www.facebook.com/groups/2359462640/posts/10162716407327641/
7) Andrew Ayers has uploaded a DSK imaage containing some pretty good
sound utilities for the Coco 3 to the Coco Facebook group, that were
originally from Rainbow: Bells & Whistles 2 by Matt Thompson, and
Super Play by Jeremy Spiller (author of Zenix and The Crystal City):
https://www.facebook.com/groups/2359462640/posts/10162716125107641/
8) Terry Trapp found out that someone was cuasing his RiBBS system
to hang up (not allowing other callers) using the old Hayes +++ATH
trick echoing back. He thinks that he has it fixed now.
His post on Facebook:
https://www.facebook.com/groups/2359462640/posts/10162715474867641/
How to Telnet to his BBS (running on a real Coco 3/512K):
telnet ribbs.griswoldfx.com 6809
9) Dannielle posted on the Coco Facebook group about her Coco based
drum sequencer through the joystick port. She is using the fire button
to sync via external clock pulses:
https://www.facebook.com/groups/2359462640/posts/10162701794527641/
She also posted a video showing it in action:
https://youtu.be/4-QPW7l5j-o?si=nzZji3LnwnqKCScu
10) Luciano Scharf posted some photos from 9th Color Rio Club meeting,
held in Rio De Janeiro, Brazil a week ago:
https://www.facebook.com/groups/2359462640/posts/10162695698002641/
11) Joel Ewy has been working on disassembling the iffs graphics
utility for the MM/1, and has hit some undocumented (as far as he
knows) SetStat calls. For those who may still have any documentation
for their MM/1's - would you be able to help him?
https://www.facebook.com/groups/3194643584094250
12) Steve Strowbridge has added After Dark, Retro Talk and Geek Talk
episodes to his YouTube CocoTalk! channel. I think he has pretty well
everything uploaded now:
https://www.youtube.com/@cocotalkforever/videos
13) Juan Castro, member of the Brazilian Coco group and Retropolis,
was interviewed on the YouTube channel TByteCreator. They covered the
Coco, Dragon, Alice and many other early systems (Set close captioning
with Brazilian/Portugese -> English):
https://youtu.be/z8REQFZ_Ql0?si=dk8_9q--2DPu0P9W
14) MrDave on the Coco Discord point out a review of the Sanyo PHC25
Japanese home computer by YouTube channel Olipix RetroTech... a Z80
style machine which uses the a Mitsubishi clone of the Motorola 6847
VDG, like the Coco, Dragon, MC-10, Acorn Atom, etc. It did come
with lowercase built into the VDG ROM, and a larger font... and a
sound chip:
https://youtu.be/FSkXsMMBAYU?si=zjMEuYeY-tJ3ZK1M&t=2209
15) Keith Frechette posted a photo of the inside of the Coco 3 he
recently required (thinking it 128K RAM)... turns out it is 512K with
an actual Tandy 512K upgrade:
https://www.facebook.com/groups/2359462640/posts/10162721560007641/
16) Tony Licari posted some photos from the Tandy catalog showing
Coco's and some other TRS-80's, but from the Australian version of
the catalogs, with Australian dollar prices from the time:
https://www.facebook.com/groups/2359462640/posts/10162720389482641/
17) The Tandy/TRS-80 people have released the latest issue of TRS8BIT,
the long running newsletter for all Tandy computers, including
Coco’s. The current issue (June 2025, volume 19, issue 2) is
92 pages:

MC-10
-----
1) YouTube channel Testudo Tech did part 4 of their series "The Worst
PC Computers Built from 1977 to 2008) - and the MC-10 is one of the
machines. The do mention that Alice was successful in France, however:
