Description

Computer

The NMS 8245 is the last Philips MSX machine (released september 1987), a successor to the VG-8235, with 3 main differences in the hardware:

  • The keyboard angle is no longer adjustable, but fixed and integrated to the computer
  • The build-in drive is double-sided instead of single-sided
  • The connector for an external disk drive has been removed

Like the VG-8235, this computer comes with 128kB RAM (not 256kB as indicated on the machine and the box by adding the VRAM). The second cartridge slot on the back is by default closed with a cover, but can easily be used by removing the cover and screwing the supplied cartridge holder onto the computer.

Note: This machine has an internal GB150H-2 NiCd rechargeable battery to keep its RTC data. This battery is prone to leaking and must be removed ASAP. It's specs are 2.4V/150mA and 17mm of pin spacing.

An important feature for this model is the bundled software package, which takes a step in user friendliness.

Three models were produced:

  • NMS 8245/00 for the Dutch and Belgian markets, keyboard layout is QWERTY
  • NMS 8245/16 for the Spanish market, keyboard layout is QWERTY with ñ key
  • NMS 8245/19 for the French and Belgian markets, keyboard layout is AZERTY

Belgium is a country with 3 official languages: Dutch - French - German. With exception for the NMS 8220 and the NMS 8280 only available in the Dutch version, also in the French speaking part (Wallonia), all the Philips MSX computers released in Belgium were different according it was in Flanders (Dutch) or in Wallonia (French).

This machine was also sold in Italy as the Phonola NMS 8245. There is also a special version for Home Banking - see Philips NMS 8245 Home Banking.

The Spanish version is still used in some parts of Spain for the Driver's License Test on cartridge, combined with a box containig handlers connected to simulate the future driver hand-eye coordination. Other MSX2 computers used for that are Mitsubishi ML-G1 and Sony HB-F9S.

It contains a Clock, Calculator, Notebook, Format Tool and 5 functions: Calcform, Charts, Database, Printer Tool and Word-Pro.
