I have just discovered these very convient self contained emulators. http://www.columbia.edu/~em36/macos9osx.html
The OS 9 one should allow me to shut down my G5 Tower.
But my question is about the Bassalisk one OS761.
I can load the software i am interested in, but it has a bug in it that means if the real RAM exceeds 16MB it breaks. We 1st discovered this when my Mac went from 16 to 20MB. Turn on a small RAM Disk so that it looks like <16MB and things were fine.
In the emulator when i try this 1/ turn on the RAM Disk, restart, crash… and 2/ even if that worked the biggist i can set the RAM disk is 256 MB.
The progrm is Trapeze 2v1 (an object-oriented “spreadsheet” that even at 30 years old shows up Excel in many ways). The complier used ignored the top 8 bits of a 32 buit word, and when the Mac thinks it has more than 16 MB every formula generates an #err.
Anyone have any suggestions, fixes, work arounds they can suggest?
