6502.org

Has anyone proposed any kinda of structured uniform open-ended design for a 6502 based system?

Something along the lines of minimum required functionality to be conforment, memory map specifications etc etc. It would still allow individuals to build their systems any way they wanted, but when software was offered to the community, there wouldnt be the problem of having to change bits here and there to make it work (I/O addresses etc...)

Hi,

We have been throwing this idea around at 6502.org for quite some time. At one point we had quite a group effort to design and produce our own board. However, in the end we had too many differing opinions about the board design and we never got past the design stages.

However, the good news is that we had all of these discussions on the old forum on DelphiForums. I've archived all of those messages here, and you can read the complete discussions here:

This should give you a lot of ideas for your own projects. I think at this time the closest thing we have to a standard would be Daryl Rictor's SBC-2 board. There are a fair number of us who have built this board. You can get the details here on Daryl's website:

There's also an area on this forum (SBC-Series Projects) dedicated to it.

Best Regards,
