Maybe you could fit a modern 5V supply into it after you removed the rectifier, capacitors and the regulator but don't take my words for granted as I have no idea if this could actually fit inside.

>Think about tape drives
The CPU controlled 6V tape motor supply circuit uses 9V(AC).
>disk drive for the C64
I don't think there's such a (real floppy) disk drive that uses the power from the C64, this is the case for Amiga but all disk drives for the 8-bit Commodore computers have their own power supply.
>even modern cartridge based add ons like ethernet.
I highly doubt that a modern cartridge exists that draws more than a 1A (this at 5V is one fuckin watt) but why you don't just post a mass produced device for the C64 where it draws more than 1A from the 5V rail.

>nobody uses original power bricks with Amigas same with C64.
I agree with this point. I rather use my own custom PSUs for my A500 and C64.

>Isn't it inconvenient to have two adapters?
Yes.

Looks very messy if both AC adapters go to the same plug.
I managed to get the 5V, 2A charger PCB inside the former 9VDC power brick (pic related). Not seen in the pic is a plastic wall in the upper shell (on the left) that will go between the transformer and 5V supply, also notice that this case uses screws.

I finished the PSU and it works... somewhat.
In the place where the bridge rectifier and ripple rejection capacitor was is now the PCB of the Samsung charger and a simple crowbar circuit (5.1V zener diode after a 2A fuse).
Opening this charger is hard, getting the PCB out can be easy but in this case i had to brutally peel the plastic case apart.
I injured myself doing that and yelled "fucking Samsung" like 20 times, just like in my job.

The cable is 2m long, i estimate the resistance of this length to be 0.1ohms.

The C64 worked nice for a few minutes and then it crashed.
And in this state it won't work anymore but show garbled graphics and lines.
I let it 'cool off' and diagnose this fault further.

Rather nice when you get used to the non-standard layout but maintenance is rather hard (getting the keys off) and complicated (need to desolder "caps lock" to remove PCB).
>The only Commodore stuff I've ever owned is my Amiga 500.
Before this i could say the same. Unfortunately i don't have it anymore.
