But not 5.0 yet - they still got critical proprietary stuff in EDIT and SMARTDRV.SYS that they don’t want their competitors to get a hold of.
I wonder if they licensed the source of 5.0+ to someone and are still getting paid for it. If so, it’s probably something ubiquitous and critical that nobody would think of like traffic lights or water treatment plants.
I think that is likely since 3.3 wasn’t included either and that is one of those versions people stuck with for ages.
Did anyone manage to build this? It seems something is missing, or I am doing something wrong. The build fails due to missing symbols for me. Also, interestingly the assembler complained about one line in a certain file being too long. Fortunately that lines was just a comment, so it was easy to fix that.
