CoCoTALK! audio episode 131 - With Floyd Resler, Chet Simpson and Inside CoCoTALK!
Some news stories for October 26, 2019 show:
1) Jim Gerrie release "Stronghold of the Dwarven Lords" for the MC-10.
2) Brian Palmer has been experimenting with custom Coco 3 palettes for the Dragon game (that works on the Coco) called Back Track:

3) Paul Shoemaker has gotten a fair bit further on his port of the Apple II version of Oregon Trail to the Coco:
https://www.facebook.com/groups/2359462640/permalink/10157585460487641/
4) Related to this: Vintage is the New World has an article on (and mini interview with) Paul Shoemaker about his port of Oregon Trail:
5) Diego Barizo has released version 4.0 of his X-Filer virtual disk utility for the Coco 3:
https://www.facebook.com/groups/2359462640/permalink/10157583688102641/
6) petsasjim1 on YouTube has been adding more Dragon 32/64 game videos, of course - a neat one is a text adventure game that not only has an interesting user interface, but allows up to 4 players.
Death Cruise 4 player:
The Dark Pit (which actually works with the Tandy Electronic Book, too!):
https://youtu.be/NLxygDDNnIY?t=96
Cyclops (Semigraphics Pacman type game):
Cuthbert in the Cooler:
Dragon Golf:
Dragon Trek (a graphical Star Trek game):
https://youtu.be/wsffitkCXP8?t=10
And another Dragon Trek (completely different), also graphical game
7) Amigos Retro Gaming did a play of Poltergeist on real hardware:
8) Dave Philipsen has a video showing some of the progress he has made on his CocoDEV board - which features an FPGA 6809 core running at 25 MHz and with BASIC.
9) Stevie himself did a couple of special Coco YouTube videos this past Tuesday. One was a demo of some BASIC games using the extended features of the CocoVGA, which included Brendan Donahe & his daughter Morgan (Brendan is the man behind the CocoVGA, and his daughter wrote the games and designed the custom characters):
His second video had Sheldon MacDonald as his guest, and he was showing prototypes of Sheldon's new Coco controllers, demonstrating multiple games with it:
10) Bill Pierce uploaded a video (from VCC) of his horizontal scrolling demo again, this time written in assembly. One thing that happened during people testing it on real hardware, is that it was causing screen glitches on real 2 MB RAM systems (both Triad+ and Boomerang E2). It appears to be a timing problem if running the computer at .895 MHz. On both boards, it runs fine if running at 1.78 Mhz) (a huge discussion trying to track down what what happening is in the comments).

And, more discussion on the 2MB / video above 512k issue:
https://www.facebook.com/groups/2359462640/permalink/10157594300962641/
11) Steve Bamford has a new video displaying a Halloween themed level in his upcoming GMC cartridge game, 'kiruke-no-shima-circe'
12) CanadianRetroThings has put up a video about his MC-10 (including his 16K RAM pack & cassette), with general info, etc. A bonus - he has a modified MC-10 which has 8K on the main board, but still only goes to 20K with the 16K pack added in. This is also labelled as "Part 1", so he is planning on more MC-10 content in the future. (He also plays Minefield, written by our own Ken Reighard). Unfortunately, I think the 8K RAM upgrade is causing problems with the 16K upgrade pack (as seen on PacMan)
13) Simon Jonassen has graphic/game demo that he has been working on for the Coco 3:
https://www.facebook.com/groups/2359462640/permalink/10157598804057641/
14) Ben Drakes has made a video playing Ken Kalish's Escape game (which was the first use of the engine he used for Phantom Slayer) using his VR rig:

7) Matchy released a video showing a Coco generating a QR code (and using the Axel F MOD file playing using Sock Master's MOD player as background music), and showing that is scannable.
8) GigerPunk on YouTube started to do long play Dragon game reviews about a year ago - on the real hardware, but I just found out about his page with his latest video, released this week.. He also reads out the original instructions, too.
When he got his Dragon:

Phantom Slayer:
Backtrack:
9) Secretly helped by our own host Steve Strowbridge, Manny Wolfe II got an awesome anniversary present from his wife & Cloud 9 - a 2 MB RAM, 6309 Coco 3 (including 2048K replacement sticker):

https://www.facebook.com/groups/2359462640/permalink/10157577927592641/
12) Simon Jonassen put up some graphic images showing a technique that he is working on of (I think) just using the primary RGB (& black & white) colors with dithering, and alternating lines vertically with red, blue and green based palettes to make it appear as if more colors are being display (kind of like a zoomed up version of the RGB phospher dots that appear in a triangle on a TV):

Episode 129 - Glenside election results
Sunday Oct 13, 2019
Sunday Oct 13, 2019
The top story this week was the results of the Glenside Color Computer Club election results, we also heard project updates from the panel, and reviewed a lot of Coco, MC-10 and Dragon news from around the globe.
Some news stories for October 12, 2019 show:
0) Glenside election results
- President - Eric Canales
- Secretary - Rich Bair
- Treasurer - Brian Goers
- VicePresident - John Mark Mobley
1) Jim Gerrie has been fixing more bugs, and slightly speeding up his Akalabeth port to the MC-10 (he even took a suggestion from Curtis Boyle!):
http://jimgerrie.blogspot.com/2019/10/retrochallenge-201910-akalabeth-another.html
Unfortunately, his blog has a later update from Thursday, October 10th, that he is running out of BASIC memory, even on the MCX-128, to be able to fit the whole game on the MC-10 - and the Coco will have a lot of the same issues. So it may have to wait until we get time to work on the a (Nitr)OS9 Level 2 BASIC09 version, where we can get >32K for a BASIC program.
http://jimgerrie.blogspot.com/2019/10/retrochallenge-201910-coco-version.html
2) Roger Taylor is sending out feelers on Facebook about a "computer on a channel" for Roku, where you will be able to use a Coco 3 emulator through the Roku:
https://www.facebook.com/groups/2359462640/permalink/10157540291702641/
3) Amigos Retro Gaming did a live stream of some classic computer game playing, including a sizable chunk on the Coco 1/2/3 (starting about 59 minutes in for the Coco). Paul Fiscarelli and myself helped supply tips & some game suggestions, and even Rick Adams popped by for a little bit.
https://youtu.be/ofiWbjGcKPQ?t=3540
4) Amigos Retro Gaming have also released the video of episode 1 of their Coco game podcast (the Coco Show) which features Poltergeist and Sailor Man
And the audio version is up as well:
5) Aaron from Amigos Retro gaming also did a video of him playing Sailor Man live, showing a lot of the features, all 3 levels, the inviso screen, etc.
6) Ed Snider has some preliminary designs for his new Coco 3+ - but this time for the case. It will have an external keyboard, but a built in MPI, and be in a compact, cube shape.
https://www.facebook.com/groups/2359462640/permalink/10157542665227641/
And an actual prototype, showing the 2 slots built in:
https://www.facebook.com/groups/2359462640/permalink/10157552612097641/
7) ShareSquid on YouTube did video play of Downland showing some tips and tricks - running on real hardware with a deluxe joystick.
He also did a companion piece - "Dumb Ways to Die" in Downland:
8) Our own Brian Wieseler has pictures of (and demo video from) the Dazzle video capture device, capturing composite from a Coco 3. It seems to be an excellent job:
https://www.facebook.com/groups/2359462640/permalink/10157550440267641/
9) Petsasjim1 on YouTube did more Dragon game play videos, including (This is not all of them by far):
Cave Fighter (a Scramble type game - but with some cool wall barriers added):
https://youtu.be/cMT1pstBFcc?t=14
Caverns of Doom (BASIC adventure game with RPG elements):
Capture the Flag:
Buzzin Bertie (never seen this one before, not sure what the goal is):
https://youtu.be/LPf-KCdYKqQ?t=18
Bust-Out! (A higher semi-graphics version of Bustout with a fair number of game options - including some multi-voice music in the background at times & win you complete a screen):
https://youtu.be/231Qys-6AUg?t=157
Bug Diver (reminds me of Shark Treasure):
https://youtu.be/iahDeU1SODc?t=9
Bubble Buster (Popcorn style game):
https://youtu.be/6XQcH1kVDIE?t=15

Sunday Oct 06, 2019
The CoCoTALKers did a whole lot of CoCoTALKing this week :) No major topic just a lot of panel discussions.
We saw an update on some new 3D printed cased from John Strong for the Ian Mavrick FD-502 reproduction cartridge.
We had a host discussion on favorite CoCo Arcade Game/Clone/Derivative that one might enjoy more than the arcade original.
And CoCo/Dragon and MC-10 news from around the web.
Some news stories for October 5, 2019 show:
1) Ed Snider announced that him and Gary Becker will continue to collaborate after the GIME-X project is done (which seems to be soon now), and will make a full blown Coco 4!
https://www.facebook.com/groups/2359462640/permalink/10157521502122641/
2) Todd Wallace has started implementing copying files between DECB and OS9 in his disk utility:
https://www.facebook.com/groups/2359462640/permalink/10157526522332641/
3) Sheldon MacDonald showed off his prototype mini game controller for the Coco (smaller than a black beauty joystick):
https://www.facebook.com/groups/2359462640/permalink/10157526519867641/
4) Jim Gerrie has an update video to his MC-10/MCX-128 Akalabeth port (The predecessor to Ultima).
https://youtu.be/2ZOsAsKzMqE
He also has a blog entry for it now:
http://jimgerrie.blogspot.com/2019/10/retrochallenge-201910-akalabeth-updates.html
5) Matchy has a new video (shown *greatly* sped up, not in real time) of 3D mapping (both outline and filled) using tessellation terrain maps. The first part is on the Coco 1/2 in semigraphics graphics; the later parts on the Coco 3 with 16 colors.
https://youtu.be/WvWuVKGc6AI
6) Interesting discussion on Facebook started by our very own Nick Marotta - what game ports (official or clone) did one prefer to play on the Coco vs. the actual arcade (not including the influence who not having to pay quarters).
https://www.facebook.com/groups/2359462640/permalink/10157528830222641/
7) "Petsasjlm1" on YouTube has been using XRoar to play a bunch of old Dragon games, which he seems to be playing in alphabetic order. I don't think he is too familar with the platform, as some of them he doesn't get very far at all. But there are some good videos of Dragon unique titles:
Backtrax: https://youtu.be/sN-RxQ_iiJE
Balldozer (Arkanoid style game): https://youtu.be/LevwtgRePfE
Beanstalker (Lode Runner clone): https://youtu.be/OKBEYaDm9tI
The Bells: https://youtu.be/MDiOrdniHc8?t=47
8) Richard Kelly put up a program to check for true lowercase T1 VDG by checking it one has Color Basic 1.3 installed. Now, the two are not tied together, hardware wise, but does anyone know if Tandy sold Color Basic 1.3 on anything but T1 equipped Coco 2's (and Coco 3's)?
https://www.facebook.com/groups/2359462640/permalink/10157526641202641/
9) Daniel Campos & Luciano Scharf have some pictures from the RetroSC gathering in Brazil, showing various Coco's and some of the Brazilian clones:
https://www.facebook.com/groups/2359462640/permalink/10157536046292641/
10) Paul Shoemaker has some pics from a possible upcoming Coco project (one of several people to delve into porting Oregon Trail to the Coco).
https://www.facebook.com/groups/2359462640/permalink/10157534949302641/
11) Amigos Retro Gaming (on YouTube) did a live stream of several of their shows in a row on Friday night. One of them is their new Coco gaming show (which featured Poltergeist and Sailor Man), but it hasn't been posted yet (Their Sinclair show, recorded just before the Coco show, just got posted this morning, so I assume that it is coming soon).
12) Retro Arcade gaming has done a Space Invaders clone, which includes several Coco/Dragon ports (including the transcode) (I would have picked Mark Data Products clone for the Coco 1/2 over the Spectral one, myself):
