As for initial conditions, a 4066 won't work? An extension to the idea: X/Y-coordinates, spyrograph-ball and increased momentum when hitting the floor.
As for initial conditions, a 4066 won’t work?

I also worked on hybrid computers when digital was too slow or expensive to get decent simulation data, and the core was all analog with digital inputs and outputs. Using that method, you can program the parameters from a digital system and run the simulation in analog, then "harvest" the results to digital files. Great for heat flow and thermodynamics as well as flight paths and characteristics of weapons systems.

I actually know that guy, but I haven't seen him in probably almost 2 years. I used to just hear talk of how he'd been to Space Camp as a kid, but on his website THERE IS ACTUALLY A PICTURE.

My Rad Shmack has a few analog heads that are always coming in for parts to keep older gear running or to mod it in some way. I always have to ask what they're building and if it's diabolical. If so the better of course, but hope springs eternal. @Mike c:

But the analog computer is cool though, I'm forwarding this page on to my grandpa who is an old school mad scientist electronics guy. The only digital stuff he touches is the 4017 cmos decade counter, and refuses to use any other digital stuff. He'll like this.

If anything I liked the beer in there just because it's probably what would be happening if you were over visiting some evening anyway. I love analog. (and a good beer doesn't hurt when the workin's done either friends) Well that’s a pretty, excuse me

Analogue circuits are hard to find these days, much less ones that do math! also, I've never tried lone star beer. I can only hope that drinking it makes me half as cool as this guy.
