should be used in the new computer. The result was arguably closer to the PET or TOI computers than to Yannes' prototype, albeit with a 22-column VIC chip instead of the custom chips designed for the more ambitious computers. As the amount of memory on the VIC-20's system board was very small even for 1981 standards, the design team could get away with using more expensive SRAM due to its lower power consumption, heat output, and less supporting circuitry. The original Revision A system board found in all silver-label VIC-20s used 2114 SRAMs and due to their tiny size (only 512 bytes per chip), ten of them were required to reach 5 KB of system RAM. The Revision B system board, found in rainbow logo VIC-20s (see below) switched to larger 2048-byte SRAMs which reduced the memory count to five chips: 2× 2048-byte chips + 3× 2114 (the 1024 × 4 bits) chips. While newer PETs had the upgraded BASIC 4.0, with disk commands and improved garbage collection, the VIC-20 reverted to the 8 KB BASIC 2.0 used on earlier PETs as part of another of the design team's goals: 20 KB system ROMs. There are no dedicated sound or graphics features. The VIC-20 has composite output, which provides a sharper, cleaner picture if a dedicated monitor is used. The TRS-80 Color Computer and Atari 400 have only RF video output. An external RF modulator was necessary to use the computer with a TV set. In April 1980, at a meeting of general managers outside London, Jack Tramiel declared he wanted a low-cost color computer. When most of the GMs argued against it, preferring Peddle's more sophisticated design, he said: "The Japanese are coming, so we must become the Japanese!" (in reference to the threats of low-cost systems from Japan). This was in keeping with Tramiel's philosophy which was to make "computers for the masses, not the classes". The concept was supported at the meeting by Tomczyk, newly hired marketing strategist and assistant to the president; Tony Tokai, General Manager of Commodore Japan, and Kit Spencer, the UK's top marketing executive. Peddle disagreed with the decision and left the company with other engineers, so an engineering team in Commodore Japan led by Yash Terakura helped finish the design. The VIC-20 was marketed in Japan as VIC-1001 before VIC-20 was introduced to the US. When they returned to California from that
