Description

The VG-8020 is the third MSX1 computer released by the Dutch company Philips, after the VG-8000 and the VG-8010 computers.

Compared to the predecessors, this machine had a keyboard "pro", not a chiclet keyboard, and an internal power supply. It has 64kB RAM (not 80kB as indicated on the machine and the box by adding the VRAM).

Various models of the VG-8020 were produced:

  • VG-8020/00 PAL (First model, keyboard layout is QWERTY)
  • VG-8020/19 RGB 50 Hz (Model for the French market, keyboard layout is AZERTY)
  • VG-8020/20 PAL (QWERTY keyboard layout and revised main board)
  • VG-8020/29 PAL (QWERTZ keyboard layout, unknown main board revision level)
  • VG-8020/40 PAL (same as VG-8020/20 with a few fixes on main board)

This model has been produced by the Japanese company Kyocera. The design of the box for the first releases was similar to the box used for the VG-8000 and the VG-8010 computers, but later the design of the NMS (New Media Systems) machines was adopted.

The case is black and silver except the French model that is fully black. This machine was sold in Italy as Phonola VG-8020.

There is also a special version for Bingo players - see VG-8020 Holland Bingo.
