There are still a few commented-out remnants lingering on my network (bootparams, ethers, /tftpboot and so on) and I think I had original floppies with the Fore software -- but might have been able, at the time, to get updated versions. I have a vague recollection of successfully netbooting 4.1.4, but falling back to 4.1.3_u1 to get the ATM drivers and software to work?

ATM is one of the very few network technologies I *never* say "I should<br>

They'd done a bunch of research on streaming video (late '90s/early '00s) and QoS atop IPv4 and ATM (probably LANE, can't recall the details now). I picked up a couple of Fore Systems switches and several Fore Sbus and EISA cards.

33.6Kbaud fax modem for a small NNTP feed and to connect my mom's NeXT to her Postscript service bureau. I'm sure at one point or another I employed smoke signals, avian carriers, sneaker net with floppies, a station wagon full of magtapes, two cans with a string... and of course, throw in an obligatory ISDN jab here too.<br></div><div><br></div><div>It was the "standing up in a canoe" of home
