Inline (68k) assembler done the hard way...
I'm ending the day with yet another possibly interesting piece of OS code I found while digging through ancient Usenet archives – the MX2 multitasking kernel for the Atari ST, written in TDI Modula-2 by a certain Fred Brooks.
I wonder if this is the same Fred Brooks who is famous for the "The Mythical Man-Month" book about IBM S/360 OS development and management (probably not)?
