Now this is just academic, for the sake of argument.
On my big box systems (2000 with MegAChip and 4000) with graphics cards, my ChipRAM RARELY dips below 1.8MB or so. My 1200 is a different story as it has nothing more than standard AGA. I will leave the 500 out of the discussion ;-)
Out of sadistic curiousity, with the number of people working on hardware emulations of the Amiga system, would it be possible to design a cheap replacement Alice to allow the 8MB Chip RAM for those using standard AGA, or would more need to be done?
Since the chips on the 4000 are not socketed, a MegAChip-style upgrade is not viable -- the upgrade would need to be an over-chip design, like accelerators for the 600. It is also apparent to me that the 1200's design lacks the support for such a hack.
It isn't just the chips. It's the data lines as well.
Honestly, if I had the time and resources I'd focus on a mini-miga like project and in the FPGA emulation crank the chip-ram up to 8mb there. Forget taking the old classic hardware that far.
Now that would be sweet. A little mini-ATX board MiniMig with full AGA + 8mb chip RAM hack, a couple PCI slots (and appropriate controller to make 'em active), and a 100mhz 060 (assuming you could ever find 'em again).
THAT would be a fun little hobby box.
