The DECB disk that doesn't work - it *may* have some hidden ML routines to disable some BASIC commands, as a form of copy protection. Or it could be corrupt.

I can't remember - you are on the Coco Discord already, correct?

What’s Up…

Nice! Love the CoCo 3 and OS9 (nitro is great). Very clear output... great job!

This makes me wish I still had my CoCo 3!

What is a good CoCo computer to buy on Ebay?

would this power a 12 volt motor, maybe 20 amp?

And you did it with a Bobbie Dazzler multimeter!

Great work, great video! Edit: The transformer and transistors you mention to form a self-oscillating circuit; aren't those the exact transistors and the gate drive transformer you refer to in the video a little later on? That's one thing that caught my eye when you were explaining the working principle at the start. The auxilary windings are often present and running off of the main transformers. The TL494 is such a venerable chip; so many designs based on them and things made with them! That also makes them incredibly cheap to make, and as such, ubiquitous in production. And hence, there's lots of them out there to break. I find a ton of them broken and with their ubiquitous nature, I can find a plethora of resources on fixing them. I love the thing! I've made a ton of projects that aren't in its intended range of uses.

Nice repair 👌👌👌

You don't have any surge suppression on your bench? Almost all of my equipment is disconnected from the mains by timer-controlled switches and all have MOV protected power strips. Lightening strikes only affect equipment that is left plugged in; use a switch, circuit breaker or contactor (unless you like fixing your own stuff).

New to Seed Pixels. My 4 ft seed tree worked great this year. The issue I am having is that 2 short working sections will not splice together to make one. Yes, I have the correct ends and +/_. Any comments on that. Thanks Jim

If you had corrosion sent 12V down the data line?

At 11:21 you say the RGB pinout is incorrect... What is wrong? Where can we get the correct pinout?

Your a pleasant guy to watch but I dont know how you can possibly complicate replacing 8 capacitors to an hour and 13 minute video... It took me 20 minutes because I had to find a non polarized cap for C20.

I'm working on the same issue... Putting Coco3 RGB through a GBS-8220. Just curious on how to create the composite sync that you mentioned around 3:14 in the video. Did you ever get it working? At 5:44 you mentioned using resistors and a capacitor for the ghetto sync. You neve posted the details of that.

Who the hell is Terry?

I just experienced the exact same problem, pretty sure it was caused by the extension cable at the remote head. The radio was intermittent with power ON until I wiggled the RH cable, and it would turn on, and then it stopped turning on. Found that fuse was open as you showed. Not having a soldering iron that was small enough, or a hot air tool, I just crushed the little fuse and there are two tabs that would stick up. Using 22 ga wire and a micro glass, a 2 amp fuse, I was able to restore the radio to working condition. All covered in heat shrink and thinner than the board mounted capacitors. Thank you so much for the video and your time and effort.

Good job dad❤

Have no power on 2019 RAM radio. What fuses would I look at?

Terry, Please share the PN for the 1.8 amp fuse? Thanks Ray

I have a D board 4K and E board 64K mod.

This is amazing!

Game changer!

Beautiful display Terry!

I did the same thing, replaced the fuse with a PICO 2A and it quit working after working for a while. And guess what the same result you ended up with. The higher current fuse allows the transistor to release smoke. Excellent troubleshooting, parts on order. Thank-you!

Could you please share the part number?

My very first board SMT way back to 1998.

No Power parts only = We didn't have a way to test it.

Was waiting to find out what series motherboard was in the machine, 'D' or 'E'? alf

Now you just have to see if it is a 32K, or a 64K (I am guessing 64K). Which revision motherboard is that one? I am guessing a D or E board.

Great Video!!

I got one of those in 1984. It was an amazing Christmas.

That is totally freaking nuts. I just did a mint upgrade on my CoCo 1. Low serial number 29,000 and change.

That's great! I don't know if I'll be able to look into this further this year, but I'm glad you're working on this and keeping it open source. I think the propellor is one of the best ways to tackle this task, and I look forward to its continued development.

I just realized there's that Microware banner on Extended Basic. I knew they did BASIC09, but since that was seemingly so different from color basic, I didn't think they had a hand in it. Maybe just some pieces were borrowed from BASIC09 and implanted in Microsoft basic.

Thank you brother, I just ordered the fuses, this was exactly the problem I had! 73's to you From AB Canada VE6WWT

Good video, but in the future you should switch the video feeds around, so the board view is larger and the facecam is in the corner. I want to see the work you're doing!

Great Video Terry

Good video Terry

Nice job

Your video capture of the CoCo 3 looks sadly familiar. I don't know why my USB capture stick skips over pixels too but it looks terrible, and WIDTH 80 is absolutely unreadable.

man you should do something about that static.. wearing headphones here nearly blew out my ears.. ! !

Still have the Color Computer that I purchased at Radio Shack when I was a kid. It's a tank and still works! If I recall, they misspelled or used the British spelling of colour in the manual.
