Sol-20 Computer

Pictured here is a refurbished Sol-20 computer. This link provides details about this Sol-20 and its restoration.

The original Sol-20 purchase did not include the floppy drives pictured here. These are Micropolis drives connected to a Micropolis disk controller. With the Sol-20 computer, the North Star floppy disk system was more commonly used than Micropolis. In the software and disk images link below is information for re-creating floppy disks for both North Star and Micropolis Sol-20 configurations.
