Description

The Philips NMS 801 is a MSX1 computer, bundled with a joystick, data recorder and six tapes with 50 games, aimed at the Italian market. It has the text "MSX Compatible" instead of the MSX logo. The reason for this is likely because the system is not actually MSX compliant due to missing features, such as no cartridge slot or printer connector. We can therefore speak of a hidden MSX!

Text on the systemboard says CELINT(UK) LTD 1989, and some units say Made in Italy. The system is also build without an MSX-Engine. The system is in physical appearance very similar to the Philips Telematico NMS 3000 and 4000, which were Italian Videotel machines.

It's a slightly improved version of the NMS 800 computer, as a RF output has been added at the back. Probably the SCART on the NMS 801 supports composite output, but it is not confirmed. The word COMPUTER on the case is in color on all NMS 801 machines.

As with the NMS 800, the box and computer did not have any label attached with any type indication, instead stickers were supplied with the machine that the user was meant to stick on it (which few obviously ever did). Only the manual has NMS 801 on it, but it was actually a sticker stuck over the NMS 800 text (which may fall off over time).

The joystick has NMS 850 written on the bottom, but the data recorder also has no type indication, except for a label that says 'Made in China'.

The box indicates 'Compatible MSX-DOS', but it's just a lie, as it is impossible to add a disk drive to this computer. Another lie is displayed on the MSX-BASIC screen, announcing 'MSX BASIC version 3.0', while this machine is not a MSX2+.
