If you happen to come across an IBM PC 5150 (which were built c. 1981 to 1987), the following notes may help highlight some useful things to do with that system (plus a few “quality of life” upgrades using some modernized components).

Much has already been written on what the 5150 system is, why it is significant, and how it came about. Here are a few references to existing discussions on those topics…

My focus below is on specific aspects of the 5150, as a guide to help those who may find such a system but might not be familiar with what it can do or how to use it.
