I made another update to my 16Mbit Virtual Boy PCB design and the new boards just came in. Red on both sides of the PCB this time. This PCB has been updated to allow a 8k x 8 nvSRAM or a 32k x 8 nvSRAM chip. The design still supports 4/8/16 Mbit flash for ROM. I also updated the design to support reprogramming through the VB connector. That will make the 16Mbit PCB design re-writable with my new Arduino mega R3 based programming adapter. Fun stuff!
