It is very iritating when you buy some stock, then you must change it because you cannot install old expansion modules.

It is very iritating when you buy some stock, then you must change it because you cannot install old expansion modules. ..I did not bookmark the posting ..it is under [LINK] somewhere. It is safe to assume that the "experiment" I refered to has failed or is not practical - a German speaker answered here already. Better you go back to your product source and try and get something worked out in getting the right hardware. You should be able to still get OBA6 or OBA7 CPUs without price penalty.. The other day I even got an OBA5 from Siemens supplied as if an OBA6. - - and yes even the OBA5 works with the same expansions as the OBA6 and OBA7. Good luck.
