VD-MB 80 Column Unit with System Power Supply and 4 Internal Expansion Slots

Priced at $300.00 in the 1986 ADAM Resource Directory, with the note that "Price varies depending on whether you get it with or without a power supply."

Detail from the directory not currently in the entry:

Designed to give the ADAM the screen characteristics of the industry-standard VT-52 terminal
Light pen port included
Shipped with word processing and BASIC software
Sits directly on top of, or to the right of, the memory console, plugging into the expansion port
Requires the composite video signal from the ADAM console to operate, and its output must go to a monochrome or high-resolution colour monitor, not a television

Owners who already had the Eve PS-1 power pack were given an allowance against the VD-MB, since the VD-MB contains its own power source
