I now have a first cut Simple Complex, this has Trinity, a simple DMA, 16kB of Data SRAM, 8kB of Instruction SRAM, 4 kB of ROM, simple word DMA, Interconnect, PIO and the Interrupt controller.

I need to test it to ensure that it works.

Note the Instruction SRAM, the intention is that this will be an area which will allow the block to receive a block of code and then run from it.
