Description

Computer

The NMS 8280 is a professional computer made by Sanyo for the Dutch company Philips. The machine itself is based on the design of the Sanyo MPC-27. The abbreviation NMS stands for New Media Systems.

This top model of the NMS serie was released by Philips on 1 April 1987. While it is very similar in appearance to the NMS 8250 and NMS 8255, the 8280 is a very different machine, as it features a video digitizer and super impose functionality. A color data bus, a control register and an independent CPU clock have been added for these functions.

The computer has in front sliders to control the video, audio mix and digitize levels and an extra button to select the input source. Most examples of this machine have 2 drives, but the first batch was provided with only 1 drive (see picture below of the box).

This computer comes with 128kB RAM (not 256kB as indicated on the machine and the box by adding the VRAM). Four models were produced, with the keyboard as difference:

  • NMS 8280/00 for the Dutch and Belgian markets, keyboard layout is QWERTY
  • NMS 8280/02 for the German market, keyboard layout is QWERTZ
  • NMS 8280/16 for the Spanish market, keyboard layout is QWERTY with ñ key
  • NMS 8280/19 for the French market, keyboard layout is AZERTY

This machine was sold in Italy as Phonola NMS 8280. There's also a rare white version - see HCS 280.

A SBC 3810 mouse was included with this computer.

Specifications

The NMS 8280 is an MSX2 with a Z80A from NEC (D780C-1) and an MSX-Engine S3527 from Yamaha.

This model is known for SCC (and other sound cards) mixing issues. There are several modifications fixing this, the opamp mod by Daemos and luppie not being the worst one.

The plastic front panel also gets very fragile with age. Special care must be taken when shipping that absolutely no stress is placed on the front panel.
