This always has a strong Coco/CP-400/etc. contingent, including multiple people who have been guests on our show.It is happening at 1670 Haroldo Soares Glavan road, Cacupé, Florianópolis, Santa Catarina. https://retrosc.org/ The World of Commodore 2024 is November 30-Dec 1 at the Admiral Inn in Mississauga, Ontario. Why am I mentioning this? Well, it's sponsored by TPUG, and they created the SuperPET (a special PET with a 6809 CPU added...) and they helped port OS-9 Level 1 to it. So it's a sister computer to the Coco after those improvements. https://www.tpug.ca/world-of-commodore/world-of-commodore-2024/ VCF-SoCal - Feb 15-16 (Hotel Fera in Orange, California. https://www.vcfsocal.com/ VCF East has had a date change for next years show due to a scheduling conflict.

This is a convenient way to do digits that can fit two per byte and can do some simple math without much conversion needed to make into ASCII to put on a screen. He compares the speed of BCD vs. the more commonly used method:: https://youtu.be/MspTilYfmX0?si=4b2PcR9EcdL7nJYo 2) Ken of Canadian Retro Things put up a video for getting a couple of tape recorders working with his Coco 3: https://youtu.be/NZ7qMBZXsB4?si=xoAJnDJmIsuDSlZ1 3) Eric Canales has released 6dev09 Build 19, and has also now made it free & open source: https://www.playpi.net/6dev09-build-19-released-now-free-and-open-source/ 4) Pedro Pena (Rocky Hill on YouTube) posted his SepTandy... errr, OcTandy video about a project that he has been working on for some time: An ATX style backplane Coco 2/3 that works with a standard ATX case/power supply. Coco 2 is working now, Coco 3 is a work in progress. Each slot has a card for a different function of the Coco, and it supports things like modern wireless keyboards, etc.: https://youtu.be/f3vT7OViMJw?si=luk4xhIDNoIH1S3t 5) Multiple people mentioned a Jason Scott podcast episode about the MC-10, where he talks about being pestered by James "Jim" Gerrie to add online emulation support for the MC-10 on the Internet Archive (via online MAME), and then goes into how much Jim has uploaded for the MC-10, and how impressed Jason is with the effort: https://youtu.be/1BW973pX6BE?si=-kCkCbVp4NYUXDNh 6) Retro Fox on YouTube attended the VCF East Swap Meet last weekend (like Henry did) and managed to get some Coco items: https://www.youtube.com/live/i5kKm1LtGKo?si=IIp1SxBfvx11emGP&t=1133 And one more: https://www.youtube.com/live/i5kKm1LtGKo?si=X2F5SC0NMdozQl3z&t=1898 7) Tazman (Scott Cooper) has been learning a little ML, and has a low res maze solving program that has a cool animated background now: (show file "scott cooper (tazmn) assembly maze version 2.MOV" from my desktop 8) Glen Hewlett posted another update to his BASIC to 6809, to which has added the faster floating point library that we mentioned last week, written by Lennart Benschop. He mentions some benchmarks vs. the Microsoft Extended BASIC floating for comparison: (show file "glen_hewlett_basic_compiler_update.png" from desktop) 9) RI Computer Museum did a quick video of a Coco 1, including showing brief gameplay of Downland: https://youtu.be/L6vzWwKtJsM?si=Xc0tO1VMkY1-SxW9 10) Jim Brain, owner of Retro Innovations and president of the Glenside Color Computer Club, posted two articles on how the external character ROM's work with the 6847 VDG chip used by the Coco, Dragon, MC-10/Alice and other computers work. Part of his research involves the original LowerKit done by Dennis Bathory Kitz back in the 1980's, and he shows some alternate character sets: Part 1: Understanding external character ROM functionality on the 6847: https://www.go4retro.com/2024/10/29/how-low-can-you-go-2/ Part 2: Expanding the MC6847: Deciphering Fonts: https://www.go4retro.com/2024/10/31/expanding-the-mc6847-deciphering-fonts/ 11) Carlos Camacho on the Coco Facebook group pointed to a cool auction that has the manual for a rare operating system for the Coco called SOS, and hoped that somebody in the community managed to get so it could be scanned and preserved. We got lucky this time - David Collins won the auction and will be receiving it soon. The community still need to find the software itself. From the Hot Coco ad (see comments on the post), it sounds like a real operating system with many calls, 35,40 or 80 track single or double side drive support, and included patches for running with Telewriter-64, Elite Word, and the Microworks Editor/assembler package: https://www.facebook.com/groups/2359462640/posts/10161768509597641/ 12) Martin Brossman posted a half hour interview with Steve Baker who is the manager of Expert PC & Radio Shack in Elizabeth City, North Carolina, and talks a little about his history selling Coco's, and his guest talks about how the Radio Shack comeback is going, from his point of view: https://youtu.be/zEfA0_tt6j0?si=EeXQdI9ep0Gviy4W 13) ugBASIC continues to get multiple updates per week. This week included some Coco fixes for the VDG (graphical position calculation) amongst other things: https://ugbasic.iwashere.eu/ MC-10 ----- 1) Dragon 32/64 ------------ 1) Richard Harding, the historian of the Dragon community, is offering some original artwork for sale that Dragon Data used for their "Selection Four" software package. I don't normally list items for sale, but Richard uploaded multiple pictures of the original artwork so I think it is worth looking through: https://www.facebook.com/groups/dragon32/posts/3856198444639796/ 2) Tony Jewell is doing a 6847 demo at an upcoming tradeshow, and he uploaded some sample pictures to the 6847 group on Facebook (these all will work without a SAM chip, so on things like the MC-19/Alice, VZ200, etc.): https://www.facebook.com/groups/173737063356725/posts/1641155646614852/ Game On news (all Coco related platforms): ========================================== 1) Nick Marentes and Jim Gerrie have been talking about some updates to Jim's MC-10 (soon Coco) port of Nick's original October 1982 TRS-80 Model 1/3 release "Stellar Odyssey", including some screen layout changes that Nick suggested. Jim release an update video showing some of those changes: https://youtu.be/sxMyQe-vcMs?si=9F_YarpMCQ1YHnNd He also released a quick video of the first Alpha of the Coco version of Stellar Odyssey: https://youtu.be/xF2R8Jrcpv0?si=biqsYwDjJHn0gIl7 And he just released a video this morning showing it running under VCC, and he mentions in the comments that he thinks he has loading/saving working, so now it is bug testing (something Nick never had to do on the original): https://youtu.be/1CDM2MWAm3I?si=oH82dtfoM5-r4a-g 2) Tim & AJ return to Dungeons of Daggorath for part 7 (G) on their YouTube My Drunk Sibling channel. By the end of this episode, an ecstatic AJ manages to completely clean out level 4, and gets both the Mithril Shield and the Elven Sword: https://youtu.be/ebujIXBlARI?si=Sg34g3D6tAh3MnQo 3) The non_maskable_interrupt channel on Youtube release a YouTube short of playing Donkey King (on a CM-8 so it's in black and white): https://youtube.com/shorts/4b5LkMbLBxE?si=xnp0-DlkVWNbHswo 4) Thomas Cherryhomes of Fujinet fame has announced (and with a screenshot) that a new cross-platform game for the Fujinet is getting a Coco version soon - Fujitzee (a Yahtzee style game). Currently in alpha testing: https://www.facebook.com/groups/2359462640/posts/10161752761667641/ 5) For those of you familiar with the programming robots game Color Robot Battle, John Metcalf is running a tournament at the Retro Computer Festival in Cambridge, UK November 9-10 (next weekend!) (the same convention/trade show that we have been plugging in our Convention/Trade show segment).

Originally written by Ron Potkin for the TRS-80 Model 1/3 in late 1979, he ported it to the Dragon in 1983. As usual, he does a very thorough review, including screen shots and even animations showing game play: https://zeitgame.net/archives/15767 8) Retrogames-co-uk did another updated of stuff he has gotten 0 and this week he got a Cuthbert Club badge: https://youtu.be/kxPaO5Ti2zw?si=jRSmhd_XsOMyMCtk&t=567 9) Steve Rasmussen (alias Buck Owens) put up a an hour long play video of Nick's H.E.R.O. game run in VCC at 2.68 MHz (so close the speed a GIME-X and GIME-Z will do). If you don't like spoilers, don't watch it all the way through - Steve goes on to beat the game: https://youtu.be/anb5Q_1PWLY?si=lLAE9eXBlSRn32zq Speak your mind!
