Regionally common hardware in The Netherlands during the 80's and 90's:
- Philips P2000T home computer (1981-1984)
- Philips MSX computer series (1985-1987)
- Philips x86 pc's (1987-1992ish)
- Tulip x86 pc's (1985-1998ish)
Apart from these, pretty much everything from the U.S., U.K., Europe and Taiwan(ese pc clones) was available over here. I think that the Commodore 64 was very popular over here (probably more sold than all Philips MSX systems combined, looking at what's left these days). Most (advanced) Japanese computers were not sold in The Netherlands, apart from some MSX models, some Sharp systems (including the early MZ-80K) and a couple portables (Canon, Casio, Epson, NEC). Furthermore some MSX computers available in for example France or Spain were not available in The Netherlands, most MSX computers sold over here are from Philips and to a much lesser degree from Sony.
In the corporate world IBM and COMPAQ were extremely dominant (like probably everywhere else in the western world).
