Interview schedule:

Interviews are being coordinated …

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).:

Upcoming conventions/trade shows of interest to Coco people:

VCF West at the Computer History Museum in Mountain View, California is
August 1-2, from 10 am-6 pm Friday and 9 am-5 pm Saturday. There are
usually some Coco people at the show (both attendees and exhibitors),
and we have had walkthroughs before that show it to be a fun show
with a lot of history since it is in Silicon Valley:

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,
and hotel booking is open already.

That same weekend, Retro World Expo will be held September 12-14 at
the Connecticut Convention Center in Hartford, Connecticut. Tickets

is a gaming oriented retro show (including tournaments) but also
includes things like wrestling:

**** NEW NEWS ORDER TO HELP OUR LIVE EUROPEAN VIEWERS ****

NOTE: We are planning to do a special “Coco 4” episode in the
future, which will included all the computers that were announced in
the 1991-1994 time frame that were supposed to be successors to the
Coco 3. We have Joel Ewy who has volunteered to show off their MM/1,
I am going to try and get my TC-9 up and running at least enough
to show it working, and Rick Ulland will show off a Delmar System
V… but we still need volunteers with TC-70’s, Kix-20 or Kix-30,
Delmar System IV, AT-306 and MM/1 B’s. Anybody still have these
machines that they would like to show off in an upcoming show? Email
me at curtisboyle@sasktel.net if you are.

also had a multi-pak, Eliminator, etc.) including custom terminal
software for the Apple II that emulated OS9 Level 2 escape codes:
https://www.facebook.com/groups/2359462640/posts/10162990398142641/

3) Somewhat along the same line are some posts by Toni W Ryan in the
Coco Facebook group talking about a Coco program he wrote for Pizza
Hut back in the day, and how a BASIC program he wrote ended up saving
them hours of drudgery previously done by hand:
https://www.facebook.com/groups/2359462640/posts/10162977475872641/
And an inventory program he wrote on his Coco 1:

4) Dannielle just about has her Coco-Musik solo album, and wants

5) Erico Monteiro posted an updated animated gif showing a possible

version 1.2, which has the following updates:

Robot Odyssey and enjoy.

longer has any frameskip!
Added ‘Muddied Green’ artifacting for the non Black/White
color set.
Added ‘Diagonals’ as a d-pad option for Q-Bert like games.
Speedup POKE is now available to boost CPU speed to an effective
1.78MHz
Fixed Skiing cart so it now runs past the ‘Get Ready… Get Set’
voice.
Boosted sound 50% across the board (it was sounding a little weak)

8) YouTube channel JimsElectronicShop posted a 5+ minute video of
6809 general info, if one prefers looking at it in video format (and
with voiceover explaining what one is looking at) rather than a text
file format:
https://youtu.be/q4awmhNgspE?si=lK0ljLwiIvHMJqzK

9) Coco Town has released another video in his series about his Moon
Patrol style game. This episode covers generating random numbers in
6809 assembly language… but generated by AI (originally done by
Glen Hewlett). He deep dives into the how the algorithm works. He
promises a followup to explain how the Microsoft BASIC one works –
which appears more truly random, but slower:
https://youtu.be/nhuOyMNIbHk?si=ZkxNY8aAq2VAloy5

10) Richard Lorbieski, owner of the resurrected Boysontech, has 3

Paragon Joystick adapter
This allows one to use Atari or Sega Genesis joysticks through
the analog ports on Coco 1/2/3’s, Dragon 32/64 (which need an
adapter cable), and Tandy 1000’s. $23 USD each

Boomerang Classic 512K RAM expansion board
Uses static RAM like most modern Coco 3 RAM upgrades, thus drawing
far less power and generating less heat than the older dynamic
RAM model. No soldering required. $24 USD each

CocoSDC – now being sold either as a kit or a fully assembled unit,
including 3D printed cases from John Strong. $85 USD each including
the case.

11) EJ Jaquay had put up a preview release of the next version of the
VCC Coco 3 emulator – version 2.1.9.3p1. This version contains some
bug fixes, as well as better support for CocoSDC emulation:

Game On news (all Coco related platforms):

1) For those who loved the SPOOKS game that we mentioned last week,
Paranoid Cactus has an itch.io page which shows a lot of different
games that he has made for other platforms (as well as Spooks
itself, which we now know will run in 32K RAM, and has 6 different
screens). And we learned a bit from the Cactus himself – he is a
fellow Aussie to Nick!:
https://paranoidcactus.itch.io/

2) Pere Serrat has converted the newest Inufuto game Mazy2 to run on
the Dragon, and you can download this updated version from the World
of Dragon forum:

5) YouTube channel Roy (Random Precision) is making a modern port of
the Dragon 32 specific version of Chuckie Egge. It’s running slow

seems to pretty well be there already:
https://youtu.be/M03Q9rr9swQ?si=FFUr64mtYfzZSMKd

6) German YouTube channel EORetro (whom we covered recently when he
showed his Dragon 32) released a 45+ minute video that aims to cover
a wide range of games on the Dragon 32. He does this with original
tapes and original cassette inlay instructions, starting with Ring of
Darkness, but including classics like Manic Miner, Downland, Return of
the Beast, Dunjunz and more. There are even some demo’s at the end:
https://youtu.be/s1GmNP3ZKIA?si=V1hLK7CNZIGHdC0C

7) Marco Spedaletti, author of the cross platform ug (Micro games)
BASIC compiler, posted a link to games written using ugBASIC, and

Coco, Coco 3 and Dragon entries, even including some Coco exclusives,
if one wants to try them out or even program their own:
https://ugbasic.iwashere.eu/games
