There were kits of the Applix available, and a blurb in ETI magazine, but things like 68K processors were obscenely expensive back then, so there was no way I was going to build one. That's all different now. I've got pretty-much all the bits in my various junk boxes and drawers to make one. Now all I've gotta do is reverse engineer the PCB layout, come up with some PAL designs, and go for it. Unlike the bee there are no issues with IP ownership and sharing.
There are four sheets - CPU, CRTC, and a couple of I/O ones. How hard can it be?
I've managed to borrow a real Applix 1616 (Thanks heaps Philip), which after a quick clean I've taken some really detailed macro photos of to help with the replication.
