The Osborne System One Personal Computer

A very early portable computer from 1982 which runs CP/M

Exceedingly rare, this specimen is probably the cleanest example of a fully functional Osborne One in existence today. As can be seen, the CRT appears as new and the unit is very low-hour. Please enjoy our blast from the past!

The unit is in such fine shape because it sat between two cardboard boxes in a climate controlled bedroom for many years after it was put away. Every few months, like many other things from the collection, it was taken out and run for an hour or so, and then put away.
