The pre-PC ones were basically SBCs running an OS provided by a certain well known CPU vendor. Original code on that side was PL/M before the whole thing went to Windows / C++.
Host side was mentioned in a sibling. It was all serial modem muxes back then, 300 baud up to 4800 baud backhaul.
Obviously it looks nothing like that today :)

- apaprocki 7y agoYes, RMX. Using a 2020 lens (pre-PC 80s were the Wild West, not diminishing any engineering effort there) the systems were straightforward. When PCs came about and everyone else was making mostly desktop software, all the real value (apps & data) remained from the very beginning “in the cloud”. It would be hard to predict that model would be exactly what everyone was clamoring for 30 years later.
