Bild der Karte mit optionalem SCSI Controller

Processor:EC030@40Mhz or 030@50Mhz
FPU:Optional 68882. (Some versions are PGA, others are PLCC)
MMU:None in EC030s, Internal in full 030s
Max Ram:32MB
Ram Type:1 x 72pin SIMM slots.

An accelerator which plugs into the trapdoor slot of the A1200. An optional Fast SCSI-II controller is also available. The card has a MapRom jumper for copying Kickstart into Fast RAM for improved performance.


There are only 3 jumpers on the card. There are two twp-pin jumpers for disabling the MAPROM and MMU and one three pin jumper to select the clock source for the maths co processor.
