I currently have a Pi Zero 2W running as an internal second processor for my Master 128.
I'm currently running with the Indigo Alpha9 build of hoglet67's code.
Everything is fine and dandy except the HDMI output which only shows a display split into 4 quarters of Red, Yellow, Blue and Cyan.
I've tried it with 2 different monitors. The same result.
Using the same Pi with older firmware. The 'Hognose' release, same result.
Using the Pi on it's own (out of the Master) with Raspbian detects and displays fine.
And also on it's own with other bare metal firmwares. Eg. Hoglet's 1MHzBus one also works as expected.
However all I am seeing when running the TubeDirect code is the 4 quarter display.
Not the following which is what I am expecting.
