I don't know what kind of network it was, but in the late 70s, I could look up inventory on a terminal at a manufacturing company I worked for. The terminal was not the main i/o (maybe just "o") as there was at least one other in purchasing, and surely one in the stockroom.
Yes, I installed quite a few SCO based applications like that. You can run a RS-232 cable quite some way. IIR there was a nice 8-port card which had a 'octopus' connection. Sorry, can't recall the name.
Perhaps ARCnet. It was popular back then, but, like everything else, replaced by Ethernet. ARCnet had an 8 bit MAC address, set by switches or jumpers.
There were a lot of proprietary networks floating about at that time. Every vendor's brother in law had one that was seeking 'lock in'. Oh, and there was SNA. Mustn't forget that! I recall going to the release show where IBM announced its Token Ring network. Well Bully! I had been working on the 1553 token ring back in the early 1970s, so this was nothing revolutionary in nature. What did strike me was that there were two groups there showing software products. One, PC based, which obviously had its roots in Ethernet type stuff, and was slim, and the other, ARRP based, from the mainframe world delivered drivers that were 8-12 times the size and had 14 different ways of opening a file. One this was the first time that either of them learnt of the existence of the other. That was the IBM of those days! -- /"\ \ / ASCII Ribbon Campaign X Against HTML Mail / \ -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
