TRS-80 Trash Talk Live #8 is Happening October 24th at 9PM EDT

Due to popular demand, we will now be having monthly live shows!  Woo hoo!

Join us for the next show on October 24th, 2020 at 9PM EDT.  We are not publishing the Zoom link going forward for reasons well known if you attended the last show.  :)  Watchers can join the YouTube stream.  If you'd like to join the interactive Zoom meeting, which is much more fun honestly, please get in touch privately.

This time around, we're going to have a presentation by Michael Wessel.  Michael is the creator of the super-cool new TRS-80 accessory, the Talker/80.  The title of the presentation is "The INPs and OUTs of Talker/80, a modern Voice Synthesizer for the TRS-80"

So be sure to join us and find out what it took to create a new TRS-80 accessory.  Maybe it will inspire you to create one of your own!

TRS-80 Trash Talk Live #7 is Coming on September 26th at 5pm Eastern

Join us on Zoom on September 26th at 5pm Eastern for another live show!

In addition to the usual revelry and camaraderie of our typical live show, we'll be having a few special presentations to make up for the lack of Tandy Assembly this year. :(

Arno Puder and Andrew Quinn will be giving a presentation and demonstration of two exciting new TRS-80 projects, TRS-IO-M1 and PocketTRS.   Here are some of the highlights:

TRS-IO-M1:

• TRS-IO port to the M1
• Supports all features of TRS-IO (FreHD, RetroStore, trs-nic, etc)
• Same code base as the TRS-IO MIII
• Has a 32kB SRAM chip included
• Auto-boot feature
• Fully Open Source

PocketTRS:

• Hardware emulation of a MIII
• Display via VGA. Color can be set to green, white, or amber
• Keyboard via PS/2
• Audio interface can be used for game sound as well as cassette input (500 Baud only)
• I/O expansion bus emulation: one can connect external cards such as FreHD
• Has TRS-IO embedded
• Fully Open Source

Then, Tim Halloran will give us a short demo and progress report on hacking the CHOMRAtrs.

Despite glacial postal service between the US and Australia and chip shortages, a few of the new CHROMAtrs boards from Ian Mavric are working (based on work by Pascal Holdry). You may not know that Robert S French released much of the software (Ira's site) and it is possible to obtain the code and work on it. That's what Tim Halloran has been up to (with help from George Phillips) -- in particular making it easier for cassette-based systems to use the board. 

So mark the date and time and come join us on Zoom.  Everyone is welcome, even fans of other vintage computer platforms.  See you on Zoom!
