The Cosmac VIP, originaly named VP-111, is a typical hobbyist "single-board" computer sold as a kit. You had to build it yourself ! The system uses a RCA CDP-1802 microprocessor like the RCA Studio II video game system. In fact the Studio II is very similar to the VIP and can be considered as its video-game version. But the VIP is also somehow an improved version of the original Cosmac Elf board system, described in Popular Electronics magazine, august 76 and the following months.
