Unidentified Emulex card from 1991

Isn't that the chip Sun used on most of their SPARCstations? If so, I disagree in at least a few respects. I *think* it has basically no FIFO, though it's possible I'm confusing it with something else - and that fuzzy recollection is talking about the part used by Sun, and I'm not sure whose part that was; perhaps AMD's more recent version is friendlier. Also, to quote NetBSD's z8530reg.h (version 1.12, in case anyone cares), * The damnable chip was designed to fit on Z80 I/O ports, and thus * has everything multiplexed out the wazoo. We have to select * a register, then read or write the register, and so on. Worse, * the parameter bits are scattered all over the register space. * This thing is full of `miscellaneous' control registers. The rant continues for another paragraph; I can quote the whole thing if anyone wants. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
