I thought every SparcStation 1 went out with exactly one Weitek WTL 3170 chip. LSI Logic was running an ad a few months ago with a photo of the processor board which showed it (along with several of their parts). And I've heard it reported that Weitek sold Sun 40,000 of those devices last year. I'm not sure about the Sun 4/110. Is its FPU a board option? Maybe it used to use earlier Weitek chips, but now uses TI's data path.
