My interest mainly just comes from the Lisa's unique architecture, both in terms of hardware and software. As I learned during my LOS compilation efforts, the OS was quite advanced for its time, and many of the decisions made in the hardware design (like soft power and the discrete-logic MMU) were quite impressive and advanced for a personal computer. I had already done the software side of things during my LOS compilation project, so I figured that the next logical step would be to recreate the hardware within an FPGA!

Yeah from a technical perspective it's really impressive for its era. OS written in a high level language, preemptive multitasking, memory protection, stuff like that. I just wish there was more software available for the Lisa. It's a shame that Apple gave this all up for the Mac, it severely limited that platform as the computers grew over time. It would have been neat if Apple had based their larger computers (Mac II, etc) on Lisa OS and provided some sort of compatibility layer that programs intended for classic Macs would run inside.
I know. In a lot of ways (at least at an architectural level), Mac OS didn't fully catch up to the Lisa OS until the release of OS X, which is pretty crazy to think about. I'm hoping that this board will make the Lisa dev tools more accessible to a people (and also a lotttt faster) and maybe that'll inspire the development of some new Lisa apps!
