Upgrading the Processor
The standard 25MHz 68030 processor in the Am iga A4000 is quite slow com pared to m ore recent
processors and cannot cope with bigger applications and gam es. The processor is slotted on the m ain
m other board.
For faster processors such as the faster 68040 or 68060 then a new expansion board needs to be
purchased and inserted via the trapdoor expansion slot underneath the Am iga.
Typical boards include:
1. 68040 Accelerators
Apollo 3040 or 4040
Supports the 40MHz 68040 and can have upto 128Mb of Fast RAM using 4 slots for Fastpage or EDO
ram . The 040 includes an MMU and FPU.
BSC TurboMaster 4053
Supports the 40MHz 68040 and can have upto 112Mb of Fast RAM using slots for Fastpage ram . The
040 includes an MMU and FPU.
Com m odore A3640
Supports the 25MHz 68040 (or 680LC40) but no additional ram . The 040 includes an MMU and FPU,
the LC (Low Cost) version only has the MMU.
GVP A3040 (T-Rex)
Supports the 40MHz 68040 and can have upto 64Mb or 256Mb of 64 pin GVP SIMMs. You will need a
extra RAM board to m axim ise m em ory. The 040 includes an MMU and FPU.
