MSX is ahome computer MSX1 compatible manufactured bySpectravideo at1985 . Popularly known as MSX 1.5 due to incorporate as default major possible extensions of time (80-column display, serialRS-232 , built-in 3.5"floppy drive ,CP/M 2.2 andMSX-DOS 1.0 asOS ; SVI always distinguished himself from other manufacturers to offer more benefits, such asCP/M or Numeric Keypads; this model is the best equip of SVI). Along with theSony HB-501 (which includes cassette), are the only attempts to make a MSX portable computer. Spectravideo delivery with a carrying case where the whole team is already in the original box, and the disk ofMSX-DOS andCP/M 2.2, which provides access to one of the greatest libraries of software of the moment.Is marketed mainly in Europe. In
Poland is marketed byCentralna Składnica Harcerska at a price of 590 000Polish złoty s (the average salary for two months at that time), which equips several schools (in fact the only team MSX is known there). InFinland also equip several schools. This version of SVI-738 was sold with altered keyboard and ROM in order to provide Polish specific characters. InSpain is initially distribuited byIndescom until the creation of the Spanish subsidiary. InUnited Kingdom is sold at 399.95Pound sterling s. Also are sold atUSA .Along with the disk drive and integrated serial port, which stands out most is the use of computer graphics chip of MSX-2, although the use of only 16 KB of VRAM allows you to add only mode of 80 columns. This and bugs in first models desing (the computer have bugs in the initial ROM disk, and cartridges from Konami chip SCC-sound do not work or have bad sound) motivates users in several countries to convert this in a MSX2 and MSX2+. Spectravideo never exploded this business, dedicated to the market for PC compatible.
