These were the prices that had to be paid in 1973. A lot of money, especially for that time. The prices are listed in 'guldens' (tax included). One dutch 'gulden' was at the time of the conversion to the Euro worth about 45 cents.

Also mention the price difference between the Unique (Standard) and the Theater version. The latter was more expensive but had a classical case and a Rithmix rhythmbox on board. Nowadays the Standard version is the most popular because Jean Michel Jarre uses it.

The following accessories could be added : a stool in 2 models, a stool with storage tray, loose cover with a lock (possibility to have it mounted on the organ) and a headphone.
