I managed a Radio Shack store back in the 1980's, and I'm now a collector of TRS-80/Tandy computers as well as Tandy corporate and retail memorabilia. I'm always on the lookout for unique or obscure items for the collection.

I grew up on Tandy computers; Radio Shack was my "Cheers": Everybody knew my name, and they were always glad I came. Now I'm living the Tandy dream with my large collection of Tandy computers spanning from 1977-1993. I'm excited to be a part of the community!

- CoCo xSID brings Commodore 64 and 128 sound and 3 voice music capabilities to the Color Computer 1, 2, and 3 via cartridge. It employs a microprocessor emulation of a MOS 6581 SID (Sound Interface Device) chip. With the use of an MPI, multiple CoCo xSID cartridges can be used with a CoCo simultaneously.
- PiKey-10 enables the use of wired USB keyboards and Atari joystick/Sega joypads with the TRS-80 MC-10. It includes a 3D-printed riser that is installed between the MC-10's case halves to provide room for such enhancements.
- CoCoVGA is an enhancement for 6847-based systems such as the Color Computers 1 and 2 and MC-10. It outputs VGA, supports all of the graphics and text modes of the 6847, and provides some additional features such as 16-color graphics, 64-column text, and software configurable character/tile sets.
- We will also be demonstrating other related software projects which take advantage of these hardware enhancements.

TRS-80 Trash Talk Podcast
TRS-80 Trash Talk was conceived in late 2015 by Peter Cetinski. Inspired by the established and successful Floppy Days and CoCo Crew podcasts, Pete figured there should be an audience for fans of his favorite platform, the Z80 based line of TRS-80s. It was also a great way to talk about and establish a community of TRS-80 enthusiasts.
The show focuses on the TRS-80 Model I, II, III and 4. But, all models of TRS-80 are covered to some degree, including the Color Computer, the portables and the later business computers.
TRS-80 Trash Talk is hosted by Peter Cetinski, Ian Mavric, Eric Dittman, Aaron Brockbank and George Phillips.
