[Coco] 1MB, 2MB, 8MB upgrades Was: Clud9 512K upgrade for the Coco3

[Stephen H. Fischer]

Will someone please refresh my memory.

TONY DISTEFANO 1 MB memory upgrade and his 2 MB memory upgrade included OS-9 programs to mark parts of memory used so that Graphics memory never had to cross a 512 KB boundary.

I have found his disk for the 1 MB upgrade with the "mega" program and I remember the 2 MB disk had a "mega2" program.

What is strange is that my last OS-9 boot disk does not have "mega2" called by the startup script and "mega2" is not on the disk.

Did I download a system patch from Delphi that made running these programs unnecessary?

I assume that NitrOS-9 includes this.

I clearly remember telling Jeff Vavasour about this and he made a change to his CoCo3 Emulator.
