Proteon P4200 and Suminet 3500H/FDDI

hmm, i haven't bothered this list about these yet, this may be a good place. i've gotten absolutely nowhere with these things. friend of mine found docs for the P4200 where he works, so i've pretty much got all the knowledge i need to make it work, sadly i lack an OS. if anyone at all has a copy of the OS for the Proteon P4200 please let me know, this thing is completely useless to me otherwise. i have found absolutely nothing out about the Suminet though. i can't find docs for it, actually i can find very little about this thing on the internet. if anyone has any info whatsoever, please let me know, it's got a serial port that looks like it would be a console, but it only prints the same line over and over (i'd have to hook it up to get a copy of the line) and it's nothing intelligable. any help at all would be great!!! cheers, -brian
