VECTREX COMPUTER MODULE

Vectrex showed a prototype of its proposed computer add-on at the CES trade show in 1983. Hope Neiman, a company official, said the device would probably be available by 1984.

The add-on will use a standard keyboard with programmable keys--their function depends on the software you're using. It will also have a HELP key: Press it, and you get information about specific programs and procedures. Price? Between $100 and $200, says Neiman.
External storage will be available on an optional wafer-tape drive for saving up to 128k bytes.

Specifications:
RAM: 16k, RAM maximum: 64k
Display Size: 2000-4000 vector drawn characters
