Kinshi, what a fascinating pair of stories. While I never used anything from ASDG, I had ICD gear under the hood of my A500 - namely an AdSpeed. I remember watching renders in Vista (not the OS, the landscape rendering tool). Back then there were two versions, Vista which did landscapes, and VistaPro which did landscapes and also water, trees, etc. and came with MakePath, which would let you do anims (although you could cheat and hand-edit scripts to make Vista do animations, which is what I did - couldn't afford the $79 for MakePath or the $119 for VistaPro). Anyway, said renders on the 7 MHz A500 were painful...but oh boy when I got that AdSpeed, it was off to the races!
It wasn't until I got an 030 card for the A1200 that replaced the A500 that I saw a speed increase.
I've often wondered - would an AdSpeed have worked in any 68k machine from that era (an ST, or an original Mac)?
