The Motorola 68000
I got into Motorola 680x processors first, and from there
the obvious path was the 68000.
Soon after the 68000 came out, Byte ran articles on not only the processor but also the
computers that used it -- foremost the Apple Macintosh, but also the Amiga, Atari ST,
Fortune 32:16 and others. When I started studying at
the University of Stellenbosch in 1985, I found the Byte shelf in the Engineering Library,
and my studies diverged somewhat from what the lecturers were trying to teach me.

My first 68000 system was homebrewed on three Eurocards. Read about it
I've been using the Quelo assembler which I downloaded from somewhere. Here's a local copy
This assembler can be used to assemble the tutornew monitor mentioned in the
comp.sys.m68k FAQ -- I get a bit-identical
image so things obviously work right.
My notes on using the Quelo crossassembler.
I've also played with EASy68K which does provide an IDE
Integrated Development Environment) but I prefer the Quelo assember.
WinHex is a Windows hex viewer / editor. It can
join two ROM (Hi/Lo) files into a single binary.
Tools -> File tools -> Unify -> Bytewise. File 1 is Hi, File 2 is Lo.
