SuperMac - the first one was the "SuperMac Spectrum/24 series III", I can't remember the name of the big FPGA thing
I built the accelerator on the last project (that 200 pin chip - look for a chip SQD-01 aka 'SQuiD') that was the basis of a whole family of subsequent cards (starting with the Thunder cards)
I loved those cards. My daily driver was a fully stacked IIfx with a SuperMac card. I remember telling my friends my display was more than a thousand pixels (1152 or something) wide.
yup 1152x870 - essentially the largest number that is roughly a 4:3 aspect ratio and less than 1 megapixel (2^20 VRAM was so very expensive) (and meets a bunch of other limitations like video dot clocks, VRAM clock rates, must be a multiple of the width of the VRAM banks etc)
I have a SuperMac Thunder/24 w/ DSP upgrade currently in a Quadra 840AV in my little home office museum here. I even have the original boxes, software, etc. :-)
I'm a fan of your work! I'd love to chat sometime.
I'm not sure how useful I could be (it was more than 30 years ago) - remember that while I designed the accelerator these boards were made by a team of smart people, wasn't just me
