I am from Mac/65 background, so it was great to find a compatible cross-assembler. Makes my life much easier during AspeQt development.

Recently I was revisiting some of my old Atari source code with the idea of doing some upgrades for the "Colleen" Atari 800 emulator on the Android platform. I was able to compile it using the old Mac/65 assembler cartridge on an emulated 800 via the Atari800 emulator on my PC, but boy, the old editor made the work excruciating. Thank heaven for ATasm! I can use all my old Mac/65 source code, editing it with a modern Windows-based editor, and crank out perfect exectuables in a fraction of the time. Mark Schmelzenbach, you ROCK. -Tom
