IF you have a DLL to support EPP under W9x, you can certainly do that. I've not
yet found one that comes with enough pre-sale doc to verify that it's up to that
kind of performance. There are a few PCI parallel port boards that claim to
have the speed, however. I tabled my S-100 bus probe a year or more ago for the
simple reason that the ports on the motherboards I was considering were not fast
enough. The PCI ones may breathe new life into the project.
The datasheet for the SMC34C60 turned up immediately on a search via GOOGLE.COM.
There's an IP product that pops up too, perhaps worth a look. Be careful not to
mix up the EPP and ECP functions on the SMC part! The two are TOTALLY
different!

Undoubtedly that's a driver for the device under Windows, and not a generic
port
driver. Too bad ...
I'd be VERY interested in seeing that
schematic, Tony! I've no doubt
that it can be done, but I wonder how fast it
will be.
The commercial ones are at least several mb/sec using drives designed for
DMA33. Only took a minute or less to transfer a set of 28 .CAB files
(w95).
The device driver runs as a SCSI device under W9x or NT4.
