As promised, here they are! I found out it also has a modelnumber : the PC-27.
Nice detail: the box still has the original pricetag: 195,00 dutch guilders (about 95,00 euro's)
It was purchased from a toystore called Dieterman. While looking for this company I stumbled on a dutchman who is a wizard in selling on Ebay with the same name (Donald Dieterman) He's specialized in toys...I wonder if he's related:-)
