I don't think so, but the parts are from c64's and stuff, so you'd need to disassemble a c64 to get these parts. I got mine from broken c64's. These chips were not damaged of course.

bottom line is: Your chips are as expensive as these broken c64's are. Which can be quite expensive.
ceci n'est pas une signature

Not really. Broken c64's are worth €7-10

I was sure they were more because I always had the impression that a working c64 was about $200-400 due to rarity, but I just checked Ebay and while they seem scarce, it seems we can easily get a working one for $100-150.

Over here they are dirt cheap. Europe ftw.

That is probably because in North America, personal computers were never popular to begin with in the 80's. Video game consoles were the thing early on, and even when the video game crash of America occured, personal computers never really took off. Then Nintendo came with their NES and you know the rest of the story.

Keoni29

Yeah I figured. In europe used (and new) consoles are more expensive compared to america.

I wrote up some documentation today. For those who are interested in lots of tech talk:

Also some new pics:

It's pretty awesome to see you can do a such small computer with these chips!

Streetwalrus

Yup. Old school PCs are tiny. Most of the size was due to the keyboard back then. And the power supply.

Also, neat machine Keoni. I already saw it working and I must say you did a great job.

I wanted this computer to be on par with modern microcontrollers, so I stuffed as many peripherals in it as possible. I still have the address space to add 4 more peripherals on the I/O board. I don't have enough physical space though :P I can maybe fit stuff like a realtime clock on it.

This looks even better than before now :D But so much stuff O.O

I made new back-boards for the computer. These do the same, but instead of stacking the boards I layed them side by side for a flatter form-factor. This allows me to build these into a case with perhaps a keyboard on top. The biggest problem I faced with the old back-boards was the lack of space. The board on the left will have the (relatively) slow peripherals on it such as serial flash roms, realtime clocks, character display drivers and so on.

Good to see you're still going strong with this project! I'll hope to see the machine in real life action one day ;)

DJ Omnimaga

Awesome to see you back into action Keoni29!  :walrii:
