Indeed, I have read some articles about people who made their own CPUs
in programable logic.
Along that line, I am still seeking basic information on HDL for someone
with no exposure to it at all. It might turn out to be simple, but thus
far, nothing I've found makes sense to me. I'm missing some key info,
apparently.

I have even found burglar alarm control panels that were based on
HC11s...
In a quick non-scientific survey, I have found that Motorola chips seem
to be used most often in systems that have a lot of I/O. My PBX systems
(mostly Mitel) use 6809, 68000, 68020, 6502, etc. and Cisco routers use
Motorola products.
Intel, namely the 8031 family, are very thick in communications gear.
Teltrend circuit packs, Telco Systems channel bank cards, Adtran CSUs,
etc have them. I think the Mars Sojourner Rover had Intel parts on it.
Microchip and TI seem to show up more often in consumer goods. I have
two different parallel port cameras that have Microchip parts in them
and I remember seeing TI parts in other goods.
I'm sure there are countless exceptions, but that's what it looks like

Jeff Bachiochi of Circuit Cellar fame has been playing with those
lately...
