The goal of this repository is to be able to interface a modern (2021 era) FPGA with a NuBus host, specifically Apple's Macintosh II and Macintosh Quadra.

Current status

First prototype is working in a Quadra 650. It implements a basic single-resolution, depth-switchable (1/2/4/8/16/32 bits) unaccellerated framebuffer over HDMI. The framebuffer can be used as secondary/primary/only framebuffer in the machine running OS8.1. QEmu tests indicate this should work with 7.1 & 7.5/7.6 as well.
