The answer to the original question is YES. Big Basic will run on MESS
configured for 512k running RGBDOS from a virtual hard drive. Why did
the program not work on a real Coco3? Well the disk I have has a code
mistake or was corrupted.
After disassembling the code for BB.512 (which is the program patch for
512k) and changing the code to what I guessed it should be, the program
runs. At this time I don't have a correction for BB.128 nor do I know
whether versions other than v2.3 will work without correction.
