Yeah...300 baud! Was pretty exciting to connect to someone back then - the thrill is definitely gone! Although FR wouldn’t lose much in text mode at least...
Inside my office, I ran 9600 bps serial between my computers until I could lay my hands on ARCnet boards. I had to port the damn driver for those. Eventually, the Ethernet boards got cheap enough to put some coax connected boards in all the house computers. Messy but fast. The house is all 1 GB Ethernet today. 802.11bgn for the wireless devices.
