A thought I had, re: a 1200 replica

It occurs to me. If we have
The online community for classic Commodore Amiga games and hardware
Not dissing the incredible amount of work in recreating the Amiga 1200 motherboard, but not all of us are either skilled enough or willing to solder on a few thousand pins of surface mount chips. The Re-Amiga (and all bare PCB recreations) really only suit a very small percentage of users.
What you're describing is MiSTer. Or, if you really want more classic IO, FPGA Arcade. And the appetite for such an "Amiga" has been traditionally quite small. Using FPGA as an accelerator has been a little more accepted, but not wide spread. Getting AGA or the 68K exact is the problem and to do so, we need the original schematics. You'll never get those for the 68K since they're still manufactured by NXP -- so your best option is still real silicon.kerobaros wrote: ↑Fri May 22, 2020 7:41 pmI admit a complete lack of experience with these things, but why couldn't you put the CPU in the FPGA as well? My first thought, before I was told earlier in this thread of Mister's relative incompatibility, was just a board with an FPGA in the middle, comprising the CPU and the Amiga chipset, with some external SDRAM and whatever else necessary to interface with the outside world. A CF or SD slot, a keyboard interface, an HDMI output (and an RGB output too, if we're dreaming) and maybe, maybe a floppy interface, if you've got enough pins left over on the FPGA to drive it. Probably not though.
