Spectravideo SVI-728

The SVI-728 was the first MSX - home computer of former US computer manufacturer Spectravideo . It was launched in 1984. The SVI-728 was the successor to the SV-328 , but it was not yet a fully-fledged MSX computer. The computer was very professional and had an ergonomic keyboard with a separate number pad and could be used as a home computer as well as an office computer. The SVI-728 was CP / M -capable and so CP / M programs could be used on this computer.

description

The case was ivory and had gray buttons that were rounded for the fingertip. The cartridge slot was in the front center. The computer was equipped with a Z80A processor with 3.56 MHz, 32 kByte ROM, 64 kByte RAM (expandable up to 256 kByte) and a video RAM of 16 kByte. The graphics chip was a Texas Instruments TMS9918A for NTSC or TMS9929 for PAL or SECAM ( YPbPr ). The interfaces were a cassette recorder connection, two joystick ports, a Centronics printer interface, an RGB output for connecting a monitor and an antenna output for connecting a television.

equipment

Some accessories were produced by Spectravideo. Because of the CP / M compatibility, 5-1 / 4-inch floppies (SVI-707) were offered. There was a 64 kByte plug-in module (SVI-747) for expanding the RAM. This gave the free working memory a total of 144 kBytes and was ideally dimensioned for word processing and calculation programs . Likewise were Modems (SVI-737), joysticks (SVI-101), graphics tablets (SVI-105), tape recorder (SVI-767), plug-in modules for a serial interface (SVI-757) and monitors produced.
