Free-running prototype and first steps to code

A project log for rosco_m68k_pro

An evolution of the rosco_m68k 68000 home-brew computer, this time with a 68030 at (initially) 33MHz and with some advanced peripherals

The prototype board I logged about recently came back from the fab, and as a first test (just to sanity check the components really) I got it free-running. Happy to say the CPU and reset / power circuitry seem to be just fine :) 

I'm now working on getting it running some actual code. So far I've identified a few issues in the GALs (which I coded blind) and some bodge wires needed on the board, but that's what a prototype is for, after all :D 

As soon as I've something to show, I'll update here!
