I am impressed by the sharp grey text on white background screen. This was DEC’s first “personal computer”, technically a VT100 with the Personal CP/M Computing Option Kit installed. The kit provides a Zilog Z-80 CPU, disk drive and extra serial port to the VT100. There may be some sort of graphic upgrade (?)
This particular machine was donated to Kennett Classic by Rebecca Landau and Robert Greenfield and will be on display at the museum. MicroMUMPS v 4.55, pascal, Z-80 assembly, and Microplan software was included, with utilities and other disks.
