Amiga Processor Peripherals


GVP TekMagic 2060

Company: Great Valley Products, US
Date: 1996
Amiga: 2000
Interface: CPU Slot
Autoconfig ID: 2017/22

Processor
68060 @ 50 MHz or 68040 @ 33 / 40 MHz
can be ordered with no CPU or with a new or a recycled 68060

Memory
four 72 pin SIMM sockets accept 128 MB RAM
four 64 pin GVP SIMM sockets for backward compatibility
the 72 pin sockets support 4, 8, 16 or 32 MB SIMMs, the GVP sockets support 4 or 16 MB SIMMs
each 64 pin slot is linked directly to a 72 pin one – only one of them can be used at the same time
cannot mix 4 or 16 MB GVP SIMMs
cannot mix single or double sided 72 pin SIMMs
a double sided 72 pin SIMM rules out two GVP SIMM sockets
supports burst RAM access when SIMMs are installed in pairs
selectable RAM access speed 60-80 ns

Fast SCSI 2 controller
10 MB/s max transfer speed
50 pin internal header
50 pin external high density connector
optional 3.5″ hard disk mounting kit
active SCSI termination can be disabled with jumper
the tekscsi2.device is not NSD compliant, it autoboots FFS partitions only – it looks for filesystems in the Kickstart ROM, but it does not care about filesystems loaded into the RDB area

Notes
68000 fallback mode with access to the SCSI controller and memory expansion
