Yes, you can do that and the perfomance is very good on the
K2-350 box here at work. I use teh 3.5" loaded one to install windows and apps as it's faster than 4x CDrom and since some systems here dont have cdrom at all it really beats floppies
or sucking it down the 10mbs eitherpipe.

I've never tried to boot one directly but I have used one as
C: via floppy boot for W95.

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

Undoubtedly that's a driver for the device under Windows, and not a generic port
driver. Too bad ...
