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 has been released by Philips on 1 April 1987. While it looks very similar to the NMS 8250 and NMS 8255, the 8280 is a little different machine, as it features a video digitizer and super impose functionality .(Color data bus plus control register for these functions and an independent cpu clock.)

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 exemplars of this machine have 2 drives, but the first batch was provided with only 1 drive (see below picture of 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 and four system disks were included with this computer: MSX-DOS1 with a nice interface, Home Office 2, Video Graphics (a new version of Designer Plus) and a demo disk.

Introduction price: ƒ 2995.

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.
