The board is sent for review, so if anyone has time this weekend to make a last schematic validation, please do so. They'll start the board Monday. A couple items: * Due to the yield issues on panels (per board cost as size goes up), I'm resisting the urge to rework the board for RAM/ROM/etc. at present. That said, If someone gets some code to work but needs RAM and extra ROM, I promise I'll spin a board immediately. The same goes for a 64/128 implementation. Adding ROM/RAM to this design is trivial. Ruud already did it. * I want to thank folks for the ideas and the responses. I love laying out boards. I also love making them multi-purpose. Thinking ahead, I went online and found that WDC offers the 65C02S and 65C22S in QFP packages. Although a bear to hand solder, adding a bit of SMT glue, SMT RAM/ROM, and an IEC connector, you truly could have an entire drive in half the space of this design. I had seen the PLCC variants, but the QFP ones were new to me. The possibilities are endless. Jim Message was sent through the cbm-hackers mailing list
