The K-Card is not strictly an A2000 accelerator but allows the A2000 to use A1000 accelerators designed for the CPU socket. When the A2000 started shipping, many people had already spent a lot of memory on Hurricane accelerators for their A1000 and weren't so keen on doing it for the A2000. Winners Circle Systems in Bekeley, California paid Ronin Research to make an adaptor to allow A1000 CPU cards (64pin DIP package) to be used in an A2000. It adapted the 64pin socket to the A2000 CPU slot. The K-Card works with almost all A1000 CPU socket accelerators.
