You make some valid points. With a well maintained system, there should be no reason to replace the original pcb. Agreed.

I saw the video was out but have not watched it yet. It makes me happy to see folks around the world being able to fix their C64 and Amiga cases. I have to admit to being indifferent about the C64 clone PCBs. Hans (bwack on YouTube) did a series of videos on how he copied the rarer KU PCB which was interesting just to see his approach. In general, though original PCBs are not in short supply, you are still using the same old chips as well. You still need an original case, keyboard, etc. Other than the satisfaction of soldering it together yourself I don't see the benefit. Something like the Ultimate64 makes more sense if you have a duff board you don't want to mess with as you can reuse the old case and KB and get all new modern innards that can run at 50mhz, has more RAM built in, 1541 emulation built in, etc. As for new M100 PCBs, it is the same story. You still need the rest of the computer, case screen, KB and you have to reuse the old chips. The most common failures I have seen are the electrolytic caps, screen contact corrosion and RAM module failure. The caps and RAM are easy to fix, and the screen problem would negate using it either way. A new 'hot rod' M100 PCB might be interesting though, an "Ultimate M100" if you will. 😊 Jeff Birt (Hey Birt! on YouTube) -----Original Message----- From: M100 <[email protected]> On Behalf Of me Sent: Thursday, May 7, 2020 3:29 AM To: [email protected] Subject: [M100] C64 restoration and fresh mobos Hey Birt, I watched Adrian's basement just now and was pleased to see his receiving some case tabs from you. That was cool. Did you see the video? I am rather impressed that someone reverse engineered the original C64 motherboard. It's stunning.
