I installed the 1.25m firmware on a 16 Mhz AY-AT board. Seems to work well, but I haven't done much with inductors.
One thing that I noticed is that blue text on the black background is VERY difficult to read (particularly when the sign-on / bye splash screens flash by in under a second) Perhaps a more contrasty color would a better choice. People had a similar issue in Lady Heather and I changed the blue to a lighter, more violet palette... it's still not all that good, but I needed to display 14 more-or-less distinct colors and a shade of blue was needed. White or yellow shows up quite well against black.
Also, any plans to implement the FET Rds-on and body diode Vf measurements that 1.12k does?
