These days, if you wish to network computers, you can use TCP/IP (a Unix standard), NetBIOS (Microsoft networking), or AppleTalk (the Mac protocol); although TCP/IP is rapidly taking over as the universal standard, you still find all 3 in use, and I believe all three platforms can utilize all three protocols.
What about obsolete and/or niche platforms? Did/do Amigas, Acorns, Tandys, Commodores, Ataris, etc., have any means of connecting computers for purposes of file and printer sharing, and, if so, did they use protocols borrowed from PCs, Macs, or Unix systems, or did some of them have their own protocols?
For that matter, does the Palm Pilot and other handheld/peripheral devices use a variation on one of these, or is it using “PalmProtocol v.2.1” or some such proprietary send/receive mechanism to transfer data?
