Help, I can't stop myself from asking rhetorical questions ...

A week or so ago I wrote (to the effect) that it seemed to me that an
analog system with little pots under the dash and some feedback (like
EGO and maybe MAP) would yield a result extremely close to systems
with lots more sophistication -- time and money.  I am unconvinced
that that's not the most effective solution.

Now, we're talking driving.  If building doo-dads is your thing (and
I've built -- and am building -- lots, but I get paid to do that), then
this post is not for you.  But, I want to take my pony (Bronco) to the
mountains and do some trails -- not screw around for the next few years
playing with electronics !

So here's one rhetorical question: what's the complaint with little
pots under the dash?  If you can tune it so it runs (and runs good),
how's some laptop gizmo that you've got to stop to type on gonna be
any better, huh?  And the laptop gizmo costs how much more than pots?

And C, or C++.  Yep, I program in that dratted language.  Clearly assembler
seems to me to be the faster and better approach for a problem like this.
So why would one torture themselves by writing in C unless the had to.
On large apps, I can see it.  Not on this one.

Then, (not a rhetorical question) does anyone out there have any 'current'
experience with FORTH.  I used it a long time ago on 8080, 8085, Z-80
systems and loved it.  The problem I had was getting it to really like
ROM'ed code -- but it worked nonetheless, and quite well.

Okay, lets have it.
