The OTHER Old School Gaming, Part 2

 Back in 2022 I kitbashed an old TRS-80/Tandy Color Computer 2 into a modern PC using a RaspberryPI 4. I had so much fun doing it, I immediately began my ideas for another Kitbash, this time using a TRS-80 Model 4 and trying to build something that would have been like the proposed Tandy Color Computer 4

I didn't quite do that, but I used the knowledge from my first Kitbash to build something new. But first I needed to figure out what to do. Well, that's not true, I pretty much knew what I wanted, I just had to do it. First I needed the case. Thankfully eBay comes through.

I scored a TRS-80 Model III case. Just the case, nothing inside. I wanted a Model 4 since they were a little bigger and white. It seemed fitting that a Model 4 case would be the start of my Color Computer 4 project.  But Model 4s were rarer than Model IIIs, but I could fix that.

Case ready to go I needed remove some internal pieces to fit a new keyboard.

Thankfully, I had gotten a Dremel for Christmas. 

Now came the longer part, finding a monitor and keyboard that would fit. I found some custom scientific equipment monitors that were even in HD and had a touch screen, but in the end I found a cheap ass monitor on Amazon.

It didn't look bad, and even had built-in sound.

I played around with a few keyboards, including a cheap one my wife and I found at a second-hand store we were dropping off old toys at.

Not really liking that one, and it later died on me anyway, I spent some money to get a really nice keyboard. Nicer than the project dictated, but I could also redo the keys to make it look like the old TRS-80 keyboard.

I knew heat was going to be an issue, so I installed some fans.

They worked out better than expected really!

Now came the time to get everything together. I scored a 5" monitor from my brother and added that to one of the drive bays, my youngest even designed and 3D printed some adapters for it fit in better.

I picked up a power strip with USB ports to power everything inside (thankful for those fans) and started putting it all together.

Components

Tested everything and spent a few hours planning where to put all these cables and unplugging and plugging back in so I was not creating a fire hazard.

Till today.

FANS!

It looks nice next to my other Kitbash.

The top bay is still empty, but I have a 3D file to print that will turn it into a 3.5 drivebay. The 3D filament currently loaded is glow-in-the-dark, since I am just going to paint it black, it seems like a waste. 

Well.

That was a blast. Now to load some old DOS games on it. That's the external hard drive in the middle. I have another monitor, I should put it up and use it for my Atari 600 and 2600 emulators. 

What should I do next I wonder.

Reminds me of a novel I read decades ago. The police in France were investigating a crime. They were searching this one suspect's house. The guy had this old French pc from the 80's. The officers turned it on and found it had been gutted of original parts and updated with current tech,
