I have for sale, in good condition and working well, a Philips NMS8280. This may be a last stage pre production model (although it is hard to be certain after so many years. I have the following reasons to believe this:
1. There is no type label with serial number on the back;
2. It comes with just 1 diskdrive;
3. The accent key (to the left of the right shift key) only has 2 symbols whilst it usually has 4;
4. All keys on the keyboard have yellowed in the same way, which means all keys are from a single supplier and often the keys from the 2nd row and number pad are much less yellowed and from a different supplier. Actually this keyboard looks great 
The price is €350. If you are interested please send me an e-mail. The address is on my profile page.
