debug could help you to see what was going on.  I was reading about 6502
assembly recently and I became very interested in getting closer to that
simplicity.  The booklet author remarked that modern x86 assembly isn't
really meant for programmers, but compilers.  I had never really thought
of that, but it made a lot of sense to me.  So maybe I should indeed
look into an older, simpler machine to enjoy the low level of things.

To validate your post: I think some C=64 retro-enthusiasts who have
never touched a real C=64, and the same can be said of other 8-bit
platforms.  Once for fun i wrote a program for the ZX Spectrum, and i
did not have access to the real hardware. Though i can remember
tinkering with a Timex Sinclair 1000.

Very cool stuff!  But I'd believe I have a certain bug to expose
relative to 8bitworkshop.com.  The machine screen first appears with a
beautiful logo and then eventually it looks like an old buggy TV with
red lanes going up the screen:

This is Firefox 133.0.3 (amd64) on OpenBSD 7.6.
