Daewoo CPC-300e MSX2

When you look at the Daewoo CPC-300e it is easy to see that this is the same machine as the Talent DPC-300 computer, both are built by Daewoo.

This is an MSX2 computer that uses a custom Daewoo IC DW64MX1 that incorporates a 8255 PPI clone, solot select circuitry, a memory mapper and various glue logic on one IC. The main CPU in this machine is a Goldstar Z8400A PS Z80A compatible.

The memory mapper of the DPC-300 is located in slot 0-2, whil most other MSX2 machines locate the mapper in slot 3. This can cause some software that expects the mapper to reside in slot 3 to not function properly.

The MSX2 Standard

The MSX2 Standard was introduced as successor to the MSX standard. The biggest improvement on the standard were the video capabilities of the system. Where the MSX-1 was quite capable with 16 colors and hardware sprites, it had some limitations. The graphics mode was pattern based, which meant that pixels were grouped by the 8, and each 8 pixels could only have one foreground and one background color. For games and pictures this meant that there was a color spill effect, colors bleeding over in unwanted areas.

The MSX2 introduced a new Video Display Processor, the V9938. This chip had the capacity to display 256 color simultanously, or have graphics modes with 16 colors out of a 512 color palette. It had true bitmapped graphics, that offered multiple in-memory pages for double buffering or vertical scrolling. The sprite system now supported multi-color sprites, and up to 8 sprites per scan-line. The Video RAM was defined to be at least 64KByte, but most systems came with 128KByte which was the maximum the V9938 supported.

The V9938 made it possible to create some great games. The most famous is the very first version of Konami's excellent game Metal Gear.

MSX I/O Ports

The follwing sections details the Standard MSX I/O ports that are available on every MSX.

    MSX Cassette Pin Layout

  • The MSX Standard calls for all MSX computers to have a standard data-cassette port. This port transports the audio-in/out signals to and from the datarecorder and the computer has a relay-switch on board to turn the recorder on and off.

  • MSX Cartridge Connector

  • The MSX Cartridge system uses a 50-pin flat-edge connector to connect to the systems expansion bus. The cartridge slot maps into one of the main- or sub-slots.

  • MSX Joystick Connector
