IMHO the Z80 SoftCard used for CP/M emulation on the Apple II. Like 86-DOS, the precursor to MS-DOS, the SoftCard was developed by Tim Paterson. Other Microsoft products of the time, such as Commodore BASIC V2 used in the C64, were not that great, though the compilers for CP/M were quite OK. Everything developed by Microsoft after the early 80's... let's not talk about that :). My work environment is Microsoft-free since I stopped using my C64 and Apple II for everyday tasks and I'm happy to own some computers for which Microsoft never published any software - NeXT workstations. “Develop for it? I'll piss on it.” – Bill Gates, in response to InfoWorld asking if Microsoft would develop applications for the NeXT Computer.
