V0.2 Mainboard

So, yes, I'm still working with the 65C02, not a 65816 yet. But I took the lessons I learned from my first PCB design, and upgraded it. The bodge wires have been updated in the schematic, and as such the PCB traces have been updated. I moved the capacitor for the EEPROM away from the top so I can fit a ZIF socket this time, and I added a full row of connections for the breadboard access to all the lines, so I'm not using dupont wires to connect everything.

I also moved the LCD display to be fully on the board now that having it hanging off the bottom would be problematic with the new bus connection there. That aligns with how I'm thinking of building the expansion bus, though I haven't 100% decided how that's going to work as it's quite a few steps away yet.

There are still a LOT more vias than I'd like, but until I get to the point of really sitting down and designing the layout more than just where I want things, I'll have to leave a lot of that work to the autorouter. It's functional enough.

Normally I don't post coupon codes, but I've been doing a bit with PCBWay lately, and I can recommend them for prototyping needs. PCB Way Coupon Code
