Re: Picocomputer 6502

That's a project I'm following. Same for Paul's Neo6502.
I was initially wondering why using a RP2040 instead of (a lot of) logic chips...
Then I realised that is precisely what happened in the computer history. I mean, the builders are always trying to lower the costs.
I do remember the first sound ...

IIgs Ram Expansion slot Pinout explanation

Hi,
I'm wondering how the address is computed on the IIgs Ram Expansion Slot....
I see FRA0..9...
The 65C816 has a 24-bit address bus.
The 16-bit low part is like the 6502. And there are the 8-bit Program/Data Bank Register.
So why 10 bits on this slot (FRA0--9) ?
And what is the use of the A10..15 ...
