Canon V-20
The Canon V-20 is a MSX - home computer from Canon , which was launched in the 1983rd
description
Canon only joined the MSX standard later and mainly implemented its in-house design line with its MSX computers. The equipment of the Canon models did not particularly stand out from the mass of MSX computers from other providers.
Canon also manufactured a hardware extension that could receive recording data such as aperture, exposure time or recording date from the data back of the Canon T90 SLR camera . Due to the standardization of MSX, the extension could also run on computers from other manufacturers.
This model differs from the Canon V-10 (white housing), which was released at the same time, mainly in the dark gray housing color and the larger memory. The relatively large cursor keys, which are particularly ideal for games, are typical of the models .
The computer is equipped with a Zilog - Z80 A processor with a clock frequency of 3.58 MHz and has 64 KByte RAM , expandable to 128 KByte plus 16 KByte video RAM and 32 KByte ROM . It has two module ports, a Centronics parallel interface (printer), a cassette connection for data storage, an audio / video output, an HF antenna connection and two joystick ports.
Text is displayed with 40 * 24 characters, the graphics resolution is 256 × 192 pixels with 16 colors, a TMS9918A from Texas Instruments is used as the graphics chip . The General Instrument AY-3-8910 audio chip provides three voices with eight octaves each .
