High Res (800 x 598)

Accelerator for the A500 and A2000 which plugs into the CPU socket. The solder points are from the tower which sits into the 68000 socket and provides it with enough clearance, even to sit above a rom switcher cable. There is no provision for inserting the 68000 onto the accelerator. Although this board will work in an A500 in a technical sense, it is impossible to physcially fit it into an a500 as the case comes in contact with it so a tower or an external keyboard would be needed.

Processor: EC020 probably @ 14Mhz (soldered directly)
FPU: 68881 probably@14Mhz (soldered directly)
MMU: None
RAM: None

The processor uses the clockspeed of the motherboard (28.63Mhz), however this is probably halved to make 14Mhz.
