Accelerator Card ACA-1220

As somewhat stated above, a 68030 is the same as a 68020 except for the slight 256 byte data cache and the option for an on-chip MMU. As not so clear is the answer that the 1220 has memory that does NOT bother the PCMCIA port. For just plain gaming, the 68020 + on board RAM (ACA 1220) is fine.  Jens has the release of the BigRam slated for this month, so I'm assuming the rest of his kit will be in the same time frame.

When computing power is really noticeable is in the 040/060 range especially with the PPC; add in OS 4.1 and you are living large.

Both require an FPU

The FPU is not "Required" nor is an MMU; the amount of memory addressable 24-lines vs 32-lines only means something if you need to exceed 16 Megabytes. It does not make the on board 68020 any "cheaper," as both will run at the same clock cycles (crystal dependent) and give the same computational power. Since the Amiga could only give 8MB of on board ram, there was no need to use a 32-bit CPU. So it made the "Motherboard" cheaper to manufacture in exactly the same way that the 8088 made the first IBM PC easier and less expensive, and of recall the Intel 80386SX did the same thing
