There's no archive at the moment. I've been trying to get a mail to news
gateway set up so that DejaNews would archive us among the other linux.*
pseudo groups. Adam Richter gates the linux-syquest list (which I also
run) but I haven't been able to get him to set up a gate for linux-parport.
Anybody know how to get Adam's attention ?

Apparently, there were two versions of the EPSA. I have an EPSA-2, but
I'd never encountered the original EPSA.

The EPSA-2 (and the EPST) both have a modified 5380 on chip, I guess the
earlier model used the real thing and the design was changed to reduce
production costs.

Don't attach too much significance to the indicator.

There's almost certainly no point in trying to convince one of the
existing drivers to work. What we can do is to try to analyse the protocol.

Please contact me directly if you want to try to crack it.
