GVP (Great Valley Products): Tekmagic 060

GVP (Great Valley Products): Tekmagic 040
Connection: CPU Fast Slot (A2000)


Processor:040@40Mhz or 060@50Mhz
Max Ram:128MB
Ram Type:4 x 72pin SIMM slots and 4 x GVP 64pin SIMM slots. (See notes below about use)

An accelerator for the A2000 which plugs into the CPU Fast slot. The card has the ability to take either the standard 72pin SIMMs, or the superior but proprietary GVP 64pin SIMMs. Please note that GVP 64pin SIMMs are not necessarily compatible with the various other 64pin SIMM formats which exist. Each 72pin SIMM slot is linked to a 64pin SIMM slot, therefore if you have a 72pin SIMM plugged in, you cannot also use a 64pin SIMM in the corresponding slot and vice versa. The card contains a DMA SCSI-II controller which provides an internal 50pin connector, and an external 50pin connector which supports autobooting. The card allows you to shadow the Kickstart into Fast RAM for improved performance, and has a 68000 fallback mode for compatibility with old software. In order you use this card you must be running at least Kickstart 2.04 and have a motherboard which is revision 4.5 or higher. By default the card never came with a heatsink or fan installed on the CPU. It may be necessary to add a heatsink and fan, especially to the 040 version. If you find your card's operation is flaky, make sure you are using the latest version of SetPatch available for your OS version.
