Yes, yes... certainly I know. The 68000 architecture was shared with
the older Macintoshes and other lesser-known computers like the Tandy 16b.

But let's *not* lose sight of the great organization and instruction set
of the MC68000. It had many of the features that made the PDP-11
architecture popular with programmers. And the LINK and UNLK
instructions were great for calling subprograms!

Although the actual machine code was much different, many of the
assembly mnemonics for the 68000 resembled the mnemonics used by the
PDP-10 assembly language.

My Atari ST was the first computer I owned that could run *real*
compiled programming languages like Pascal and C. That helped me
sharpen my programming skills and gave me the realization that
microcomputers were going to be running things in the future.

The Usenet groups in the 1990's posted the source code for Atari ST
programs and were instructive to budding computer coders. I remember
that the Atari ST source code groups would have much more code than the
Amiga group... probably because the Atari was cheaper and easier to buy
for a lot of folks.

I remember writing a program to print out the Mac graphic files on an Epson-compatible (Panasonic) 9-pin dot matrix printer. Once the picture
file is decompressed in memory (the 1040 ST had enough memory to keep
the *whole* picture in memory at one time!), the trick was to "pull out"
the pixels 8 at a time in *vertical* order... the way the printer
wanted to receive the pixel data.

I too converted a program in Algol (published in the Nov/Dec issue of
Creative Computing magazine) into OSS Pascal... that would draw Koch "snowflakes" on the monitor screen.

I put together a program to use the entire monitor screen to plot an
Ulam spiral, which is a depiction of the distribution of prime numbers. Although simple in concept, *many* primes have to be plotted to be able
to recognize the linear pattern in the picture.
