Wow, this is big news, and thank you for your efforts Alex! I can't wait to own one, and I will want one.

Now I just need to figure out why it looks so terrible...

Incredible! Where do you find the time??
Nice work!

Progress has been great so far, but it's probably going to be a while before we get to that point of other people being able to build one! Getting I/O working and deciding how much I want to modernize that stuff as opposed to requiring the use of original Lisa hardware (like adding native support for USB keyboards/mice vs making the user plug in Lisa originals) is what I anticipate to be the hard part.
For instance, I'm working on piping the Lisa's video output straight through HDMI right now, and that's proving to be a bit weird/challenging in several ways. But it'll be nice once I succeed because then we'll no longer have a need for an RGBtoHDMI, and the Lisa's contrast control can be simulated by simply adjusting the intensity of the white sent over the HDMI link.

Just working on it whenever I'm done with school and homework for the day, and as much as I can on weekends. The PhD program keeps me busy, but luckily I've still got enough spare time to fit in a couple things like this!
