It had a full-travel keyboard, unlike some early home computers that featured membrane keypads (and earlier kit machines that used switches), but with a very non-standard layout.
[9] It was able to output 384 x 336 graphics [10] and 128 x 56 semigraphic characters[11] in 16 colors, (based on UV-201 and UV-202 proprietary chips[12]) and sound to a connected television set through an RF connector.
The system included four built-in software titles, available if the unit is powered on without a cartridge inserted - a simple text editor, a clock, a countdown timer, and a Color Bar generator.
It allowed users to connect a cassette tape recorder for saving or loading data, and included two RS-232 ports for attaching a printer and the Expander 2.
The Expander 2 was a 300 baud acoustic modem used by a single program (Timeshare) that allowed the VideoBrain to act as a terminal when dialed into a compatible mainframe computer.
[9] Patent 4232374 titled "Segment Ordering for Television Receiver Control Unit" describes the VideoBrain display hardware.
Poor design decisions hindered user acceptance; for example, the VideoBrain's confusing and user-unfriendly keyboard made even simple text entry a tedious process.
(By contrast, video game consoles at the time were easily available in a number of department and toy chains, allowing them to far outsell the VideoBrain Computer System).
[14] Albert Yu said, in a 2005 interview, said he had invited Andy Grove to look over the system and he was skeptical – wondering who would want to buy a computer for the home.
