Do you have a video on how to calibrate?

It always boggles my mind how disgusting some of these computers get. I'm glad you were able to save this one.

Can't you just add a 5V zener to the main PCB? Does this also affect C64C's? That one does seem to have a rectifier and voltage regulator on board.

2024 SUCESS FULL😉

I like your videos

Not sure Those standsoff Will last 🤔. They are soft in the middel. At The end where The joystick was inserted, The board moved slightly. But a Dahm good repairjob. I guess i would have attempted to throw The board as a frisbee After a week 😂

At around 31:00 I would have used HALF a potato, to make sure it is much more stable! Thanks for the video!

Where can I buy this programmer? Thank you very much, excellent video. Greetings from Spain

Hey atleast yours has a real transformer. Mine came completely empty. Theres a tiiiiny switching transformer on the front panel pcb tho.

Should do diode transistor curves also.

Hi. First thanks for the video(s). Did you manage to put the display in the case? May I suggest putting it in a different case and then daisy-chain it? It would make an interesting video for those of us who are not that inclined to electronics, but are willing to learn. Kind regards, Pedders.

This video is hilarious to me because I have been using this thing for so many years, it's held up great. I always unplug after use though because I don't trust any of this cheap, chinese crap so maybe that's why. I never had to open it either. It was used for SMD rework no problem, I eventually purchased more name brand solutions, but came back to using this thing because it was so consistent, just a workhorse. The $30 I paid on eBay made me a lot more than I invested for sure. Thank you random chinese assembly line worker!

I'm so glad you used blue tak and didn't bend the resistor legs! It makes desoldering easier.

The metal shield is to make the computer compliant with the EMI requirements of the day, not heat. So while it may not run any cooler, it may save your life over 20 years of exposure :)

Seems mine is grounded to the tip. However my lights flicker when its plugged into the same outlet as it. Idk how I'd fix that. Could just be high power draw?

Where's Part 2? The CoCo 2 was my first home computer. It was pretty primitive and obsolete by the time I got mine, so I don't think I appreciated it very much as a kid. But it was a computer in my home in the '80s, and that had to count for something.

Mark i want to do part 5 you can ask him?

Another note about RoHS compliance: Do you expect to put your C64 in a dump? Because that's what RoHS is for. Lead-free processes expose the operator to more toxic materials so that when careless end-users throw out their work it doesn't poison the environment. Use lead-free solder, sure, but consider the reasons why and the ultimate benefit your decision will yield. Electronics can and should be recycled, and there are other environmental costs to producing new materials.

About "complex and expensive" when it comes to logic analyzers.... that is no longer the case. A Pi Pico costs $5 and outperforms any digital analyzer that would have been available to the C64's designers in the 70s. And can probably even serve as PLA while doing so... maybe not for Super Zaxxon tho.

I was sent an unfused plug on mine first time I’ve seen an unfused uk plug

Hi Mr so many people are screen protector plastic take out trow away why protector is screen protect or damage please answer to me TQ

Hi dear. Plz if u can tell ncv accuracy for wires inside wall??

First time discovering your channel and video, from Robin Show & Tell. I just downloaded the MasterRom file to my PC, for a future Commodore 64 build I would like to do someday. As far as I know, I might be the first or very few people in the USA to have this MasterROM; especially in Kentucky USA! Looking forward to loading the ROM's into my next Commodore 64 build and experience it first hand! Initially I was going to build my own C64C computer completely from scratch, with a parts kit, new motherboard, chips, case, etc. Unfortunately, that would quickly run way out of my price range. So I found an alternative DIY Commodore build I can still do for half the cost; but still quite expensive locating all the custom chips and shipping costs from Europe. But will see how it all goes once I have the money for it. I would guess Commodore themselves never knew about the MasterROM Kernel released back then. The developer being so obscure in the deep wooded cold frontier of the Great White North eh! 😃👍

Where did you get the resistor reference tester? super cool

Hello, I would like to ask, I am making a PCBs and I am interested if it is possible to use this multimeter to measure capacitors from 100 pF to micro, resistances from 1K to 1M and if this multimeter will not destroy my board where all the components are very sensitive, for example SHTC sensor max 1.8V. Overall, I'm wondering if it's possible to use this multimeter on smt PCB, it doesn't have to be that accurat. Thank you.

the "fun" part of removing the keys became breaking a piece... no need to remove keys for a cleaning that you can do with the help of a little alcohol and a small brush. You can clean the metal contacts with liquid for polishing metals and a cotton swab, and clean the conductive rubber that makes contact with a cotton swab and alcohol.

How can one detect when the lever of the zif socket is closed?

hey, good clip, and a very interesting for computer freaks (returnees-dude), like me !a good 2023 all retro freaks.and thanks for upload.!

hello from germany....thaks for your channel. you have awesome content!! sorry for my bad english, but my sub have you! have a very good time and all best from chemnitz...

may the zero force be with you

Outstanding as usual. Loving it. Thanks.

3:34 that's what she said

this Zoomed Video is just awesome!

Hı can we use this programmer för s3 4c dk 94 chip

We don't need no stinking Arduino or USB avr.

Hm, no way i can insert these cheap ZIF sockets to the C64C's IC holes... although there is no any solder residue in them (using a vacuum desoldering station), the ZIF's legs are just to big/wide. Any idea? I'm thinking of file the ZIF legs to make them smaller, but this can expose the legs to faster corrosion maybe... don't know what to do.

This kind of project is worth doing [again]. It's how I discovered your channel and is very interesting.

Impression that the package got hot enough to loosen the hot glue and also mess with the solder joints on the boards a little. If it takes a hot iron to loosen the PI in the previous build video, it seems likely that it could have gotten pretty hot during shipping.

Hello! Your video is fantastic! I would like to ask you something can you tell me where i can find the diagnostic catridge for Commodore C64? Thank you!

I have Commadore 64 C with same shielding and wondered about this myself. That's hot.

I like your approach. I have been fixing a few Commadore 64s and finding solutions through research. I'm not an electronics guy. You really don't have to overthink most of it.

Shouldn't you glue down those caps? They're flapping in the breeze now. I see lifted pads in the future.

2:28 That's a bevel tip, not a chisel.

Excellent video as always, keep it up!

I couldn't agree with you more about the liquid tape. Great product, horrible built-in brush. Thanks for sharing your work!

downward dog is the best way to bend a capacitor to your will. *evil laugh*

I never saw caps being installed like this. So we don't really need to thread it through the PCB holes?

Just wanted to say that I very much enjoy your content and hope to see you continue into the new year - at your own pace, because I totally understand scripting, filming and editing videos can be a chore (I personally find the editing process to be a pain). Thanks for all that you do!

Very entertaining Mark. Especially the section on hand scum was educational.

With the 7+ month journey from beginning to finished repair, the "SAGA" typo in the intro is very appropriate! :)
