I have added support for it, but I also rearranged the code a bit to make it shorter. However, I am not sure everything works as expected. Lower case and many obvious special characters works, I can enter them and ARCLREC then PRA it to the printer. Then there are some that I do not understand what they are supposed to be. Pi is a star burst and basically a checkered square when printed?

How to test it properly?

Because of this, I also added the lowercase patch to [MASK] - so it's all coordinated and that's a much more convenient way to test it. Also it all runs on V41, which shows the lower case on the LCD quite nicely - so no need to print them (which as you say has some quirks)...

Using your alternate OS on V41 should be possible, just replace the NUCXT.MOD with your new set of ROMs... I can prepare a new MOD file if you want, but I know you don't use windoze (with good criteria) - so can you emulate it on your system?
