Since the 4000 was the top of the line Amiga, I'm curious which OPi AmigaKit is going to use. The OrangePi Zero 3 has a big advantage that it is inexpensive and does the job very well. I am curious if they are going to go with a more powerful SBC like the 5 or 6.
If they do decide to go with one of the more powerful SBCs, the price will go up as the series 5 boards are going for $82 - $140. The 6 series boards, the Plus with 16GB RAM are $245-$299.
I think it would be really cool if the A400NG is the powerhouse by incorporating the top tier OrangePi SBCs, just be forewarned the the price will go up considerably.
What would be even crazier is if they went with the RV2 SBC with a native RISC-V build of AmiBench!
