M-Tec 68020-i

Processor: 020@14.32Mhz
FPU: Optional 68881 or 68882 (PGA or PLCC) at up to 50Mhz
MMU: None
Max Ram: Probably 4MB
Ram Type: 1 x 72 pin SIMM slot.

An accelerator which plugs into the CPU socket of the A500 and A2000. It probably works with the A1000 too, but his has not been confirmed. The card requires an additional crystal if you intend to install an FPU, which allows the FPU to run at a clock speed independently from the processor. A 68000 can be installed onto the card as a fallback for old software that is incompatible. There have been problems reported when using this card with an A2091
