IIRC from when I had an 81/110 as a daily driver, the SCSI busses on the 81/110 are the same as on the 8100; twin normal 5MB/s SCSI busses. I had a pair of drives striped across the busses to get almost 10MB/s while it was running Linux as a web server.

The "System 100" was an 81/110 bundled with a Thunder IV GX 1600 video card, FWB JackHammer SCSI card, and a Fast/Wide 2.1GB drive, to the best of my recollection.

There is a 2MB soldered version of the HPV card that takes 4 x 512KB VRAM SIMMs for a total of 4MB. It shipped in non-AV 8100s. I sold one on eBay a few years back.

That 4MB HPV card is the hot ticket in these machines unless you want a bigger resolution than they support. It's just a dumb framebuffer, but it's on a 64-bit bus at 33 or 40MHz. So, the CPU has far more bandwidth to the VRAM than any NuBus card. QuickDraw acceleration mostly just helps to make up for the slowness of NuBus, in my experience.
