Ram Type:4 x GVP 64pin SIMM Slots.

An accelerator for the A2000 which is designed to plug into the CPU Fast slot. The card takes GVP 64pin SIMMs which are not necessarily compatible with the various other 64pin SIMM formats which exist. The card also contains a SCSI-II controller providing both an internal 50pin connector, and an external DB25 connector. The card has a 9pin serial port on board and a connector for attaching 25pin parallel port backplate. The parallel port can be configured to operate like a convential Amiga parallel port, or more like a PC parallel port. The card also contains a connector for attaching the GVP Spectrum 110/24 graphics card.
