PEEK inside the MPS-802: the most misunderstood dot matrix printer for the Commodore 64! Today we'll rebuild one and talk all about it, including tips for general maintenance, and a test print.

N.B.- Also marketed as the Commodore 1526 for the VIC-20 with cosmetic differences -- and ALSO as the Commodore 4023 with a parallel IEEE-488 interface instead of the familiar IEC serial.
