SMSC once sold a chip (34C80?) that was the target end of the link, and they published an application that produced a standard 8 MHz ISA bus via the EPP, including DRAM-compatible timing. I've used EPP but never in multi-byte mode, as I wrote the interface software in Borland 'C', which doesn't do 32-bit I/O, and I'm curious whether anyone has used it with a compiler/assembler that actually was able to write or read 32-bit words to/from the data port. That's purportedly how one gets the high data rate.

There's been lots of writing about it, about 75% of which is actually wrong, but I've never actually encountered anyone who has used this mode to accomplish useful work.

I've got a couple of things that I want to try out, that will benefit from the high data rate, but I don't want to bother with plowing up new ground if it's already been shown to be inadequate or unreliable, as this has to run for a long time without a hitch.
