I have a Model 1 with a FreHD and it boots great but I have a lowercase issue.
I have tested the lowercase with the program on page 108 of Custom_TRS-80_and_Other_Mysteries_1982 and it works fine
On the FreHD boot screen the text is all uppercase. If I boot M1LDOS6 the date and time are lowercase as is the word "Copyright"
Once booted with the lowercase driver loaded it is always uppercase. If I do a DIR all file names are uppercase. Shift 0 does not function either
The Ready prompt is READY not Ready
The board is a G board 2 roms and boots to basic with R/S L2 BASIC
Any ideas were to start looking
