===== T030 mk.II - 68030 SBC =====

The T030 is my attempt at a 68030 based single board computer capable of running Linux.

The mk.II version has the following specifications:

68030 CPU running at 25 MHz

512 kb ROM/flash

512 kb SRAM

64 MB DRAM (4 x 16 MB 30 pin SIMM)

IDE port

RS232 TTL-level console

SPI bus with 4 chip selects
