who knows: Celerity [GEI Rechnersysteme] ?

hello ! someone offered my a Celerity computer from 'GEI Rechnersysteme'. it is mounted in a 19" rack and has a built in tape drive. unfortunately they cannot provide me further information. so I would like to ask you on the classiccmp-list: - where can I get further information about this machine ? - what hardware is in it ? [bus, cpu,...] - what operating systems run on it ? - should I take it or leave it ? thanks for help, Andreas -- ********************************************************* * Andreas Mueller * * * * Multi-Media-Labor || Uni-Tuebingen * * phone: +49 7071-2978567 or +49 7071-2977821 * *********************************************************
