@ -8,4 +8,6 @@ The goal of this repository is to be able to interface a modern (2021 era) [FPGA
First prototype is working in a Quadra 650. It implements a basic single-resolution, depth-switchable (1/2/4/8/16/32 bits) 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.
Some basic acceleration now exists for 8/16/32 bits, doing rectangle screen-to-screen blits and solid rectangle fills.

There's also a basic RAM Disk using the 248 MiB of SDRAM not used by the framebuffer.
