It would seem that the circuit was intentionally
simple and straightforward: a M68K cpu, ram, rom, two 6850 UARTS and the circuit to drive
the display. The key aspects of the video circuitry (and mouse circuitry) are discussed in
this paper:

Graphics on the Blit”).
Thanks!
It would seem to me that doing a version of the Blit
that runs on a FPGA board and generates 720p HDMI output would not be impossible to do,
It actually pretty simple, all this stuff is avalable on AMIGA emulators
for FPGAs ...
if the software can be configured to deal with a
different geometry (e.g. 1024x720 instead of 800x1024). Whether that would be much
different from running the emulator on a PC remains unclear, of course.
It is on my list of things to do, but not on the first page ;-)
Still waiting, that schematics & sources show up ...
