The Philips NMS 1255 is a data communication package consisting of a modem cartridge and software on disk:

  • It can operate at different speeds
    • CCITT V21 - 300 BAUD Bi-Directional
    • CCITT V23 - 1200 BAUD receive, 75 BAUD send
  • the disk contains version NMS 8961/23 or 24 of the Philips MSX Data Communications software created by Computer Mates, a UK company. It supports
    • Videotex / TTY modes
    • File transfer
    • Auto-dialing / Auto-answer

This package was only available in the Netherlands and had a fixed Dutch telephone connector. Note that the label on the modem is actually NMS 1250 while the label NMS 1255 is used on the box.

This modem was also marketed for use with Home Office 2 sold apart, but also included with the NMS 8250, NMS 8255 and NMS 8280 computers.

To combine both software together, you need to copy all the .COM and .OVL files from the MSX Data Communications disk to the Home Office 2 disk. A seventh icon will appear on the main menu of Home Office 2.

This modem was also released in a version open to other markets than the Netherlands - see NMS 1250 - and was preceded by a pre-version, though sold only in 1992 - see Miniware M4000.
