I haven't worked on this much for the past 3 years. But yes, I am still alive, and I have been making progress recently. The big thing I've been working on is a board that has RS-232, an EPROM programmer, and a memory bank switcher. The memory bank register can be turned off because I have some plans to possibly implement some other complicated memory scheme with segmentation, or some other virtual memory-like function.
But we're back better than ever because now I'm making some PCBs instead of hand-wiring everything!
