***************** I have checked the PD lists but I am not yet sure that what I am looking for (and need) does not exist. Is anyone aware of an 'analog computer' emulator for the AMiga ?? I have a set of linear differential equations that I want to fiddle with and I would like to get an idea of their behavior graphically . (It's the graphical interface that really interests me. I do have the program that implements the for the Runge-Kutta algorithms.) If no such thing exists, is anyone aware of an actual (and cheap !) analog computer that I might be able to buy via mail order or any other way? Any and all help will be appreciated. I might even be willing to pay some hundred(s) of dollars if anyone is interested in cranking out something along these lines. Really! I really do need it! You can post info here or send me email at: hubey@pilot.njin.net or hubey@apollo.montclair.edu Thanks to any one who can help me. mark -- ----------------------------------------------------------------------------- hubey@pilot.njin.net | hubey@apollo.montclair.edu | ...!rutgers!njin!hubey -----------------------------------------------------------------------------

I don't know of an analog computer simulator (it's an interesting concept though) but I do know the "Doug's Math Aquarium" will plot differential equations. It'sn't (a neologisim for "it is not") PD though. >If no such thing exists, is anyone aware of an actual (and cheap !) >analog computer that I might be able to buy via mail order or >any other way? Any and all help will be appreciated. Building analog computers is easy with op-amps. Check out any cookbook of opamp circuits, buy a bunch of 741's or something and wire them up. --Chuck McManis uucp: {anywhere}!sun!cmcmanis BIX: cmcmanis ARPAnet: cmcmanis@Eng.Sun.COM These opinions are my own and no one elses, but you knew that didn't you.
