Back in about 84. We were users of bridge cs200 serial boxes. Communicating to a unibus board in a borrowed 780. From memory the network communication was a xerox protocol. A while later we were given a 750 to which we moved the unibus adaptor. And subsequently upgraded to tcp/ip which required a

Thinking back to those times. The other battle within the office Dec v Unix camp was for the dominant terminal server protocol. Never put it to bed as so much invested in Dec lay devices. Bridge tcp/ip devices. So only one solution. Woolengong tcp/ip on the VAX systems and lat emulation on the sun

Gee, Johnny .. don't be so negative. Just kidding! But seriously, this is all such a "blast from the past" .. I didn't start as early as many of you guys, but I certainly remember building many, many servers by getting the machine up far enough that it would run a serial port, then going back to

DEC's DECserver, Xyplex Maxserver, Annex terminal servers, and Xylogics (for the ones I have touched and remember) all converted telnet into real RS/EIA-232 lines. (telnet client -> host serial, or serial terminal -> host telnet server) These days the Cyclades ones aren't too bad. Newer ones turn
