In my last video, I repaired the keyboard on my CoCo 2). In this video, I will begin upgrading this machine with more RAM, and an Extended color (colour) BASIC ROM. This Coco 2 has a rev. 20261044 system board which will make the upgrade process fairly easy. I am still researching how I want to go about the video upgrade on this retro-computer , so if you have any recommendations about the best method, please comment.

Be sure to watch the first video where I repair the keyboard membrane. Part 1: https://youtu.be/TvSog3ZTf9c?si=80Ag_tB194CMRVSB

I also have other videos related to the original Tandy Radio Shack Color (Colour) Computer. https://youtube.com/playlist?list=PLB0ffa2MA6bti0f6EMWmbwltB-piJwbSB&si=_of8N-D16_T0VkJq

I finally got ahold of a TRS-80 Color Computer 2. In this video I’ll look at DIY methods to repair the broken keyboard without replacing the keyboard’s Mylar membrane. This CoCo 2 is a non-extended 16K machine, and I’m looking forward to upgrading it to 64K with Extended Color Basic, and composite video. First though, I need to get this Tandy Radio Shack retro beauty fully operational.

As much as I like the CoCo 1 that I recently obtained, it is pretty limited without a way to save programs. I’ve found a great solution in an old Sanyo cassette player, but I will need to make the appropriate interface cables to get it working.

In this video, I share the newest retro-computer in my collection, a Tandy Radio Shack TRS-80 Color Computer 1 (or CoCo1). I’ll also share just a little bit of personal history that makes this Radio Shack computer special to me.
