Can I upgrade Amiga 2000 CPU IC? :confused:
If you can find a used one, Supra's Turbo28 (clocks at 28 MHz), with it's buffering, gives a very substantial acceleration. It is not a single chip, it plugs into the acceleration slot. Like the original 68000, it is 16-bit and clocks 4 times faster than stock (about a 3.5 X speed boost). Also, unlike more expensive 32-bit accelerators, memory will still be limited to the original 16-bit map (8MB Fast, 2MB Chip). I have an A2000 equipped with one and like it quite a lot. The only incompatibility I have noticed is that Bridgeboards don't like it. It is the same board for the A500 and A2000 and will work with either computer. Those sold for the A500 came with a side-car case (removeable).
If you find an ICD AdSpeed accelerator (14 Mhz), run away. They are unstable and have many incompatibilities. They do, however, mount in the CPU socket to replace the 68000.
+1 about the 68010. I use them in A500s, and with some Fast ram, give just a barely noticeable speed boost.
