Fwew.. what a pain. That larger CPLD had tons of space but due to those longer wires there was quite a bit of noise that made it tricky to clean up. After weeks of working on this guy I was finally able to get it working.
That's it for the CPU/Video related customs which means I can start preparing the RTL for the FPGA development platform. Stay tuned for those updates.. I hope to start a video series that captures the progress from here on out.

June 2012 Status...
Making a lot of headway on the hardware design. I have all of the CPU and Video PCB logic coded up in verilog (with the exception of the sound stuff) and simulating. The Z80 and Z8002's are working (in simulation....so far) but its becoming apparent to me that I'm gonna have to toss this thing into a devkit soon to iron out the bugs. It literally takes hours of simulation time just to get the system out of reset, which happens in a matter of seconds on the actual hardware.
On another note I've started work on the 09xx series custom. I tried programming it into my FpgaArcade device but alas.. it was too small. Time to bring out the big gunz!

Fluke z8000 pod acquired
Many thanks to fellow KLOV member Paul Olson for lending me his Z8000 pod!!!
This will help me keep my current PP boardset working and experiment with the hardware as well.

Annnnnnnd we're back!
Well the lab is finally setup and fully operational. With the big bench in place I now have a dedicated station for the PP project. I plan on returning to this project this week
Very excited to make some forward progress...
