Didn't notice no ASIC. It's basically the same as the Rev. C, only that
it can take 1MB of cache and the GALs that do DMA are altered so that
it can DMA to all 8MB (the RDY trick). All the chips are SMD, but there's
no ASIC. Definitely not. It is much smaller, that's true.

Rev. D. Apparently the "refurbished Rev. Cs" that were floating around
a long while ago could do that too, they had the upgraded GAL. Haven't
seen an ad for those in a long while, though.
