Description
The VDM-1 generated sixteen 64 character lines from data stored in a 1024 8-bit byte on-card RAM memory. Alphanumeric and control characters (the full 128 upper and lower case plus control ASCII character set) were displayed in a 7 x 9 dot matrix. With its EIA video output, the VDM-1 could be used with any standard video monitor. (A TV set could be easily modified for use with the VDM-1).
