Reading through the DEC Installation guide made it look so easy!
In reality not so, it seems?!
I plunged my 256k RAM chips in the sockets, set the jumpers on the memory
board to the according position(on,as mentioned in the manual), and then
blue-eyed me believed everything will be the 896kHEAVEN. The FSOAB didn't 
feel the same way, so here goes nothing -> -> -> ->


W H A T   H A V E   I D O N E   W R O N G ???

Are there any jumpers on the mainboard to be set, that are not mentioned
in the beautiful manual @#@!!???

The only difference in layout between 4164 and 41256 is that pin1 has A8
on, whereelse on the 4164 it's not used, therefore I flicked the switches
to "OFF" and there you go, I had 512k available. What's my problem??

Second question: If it is my mainboard, and I can only use the RAMS as 64k
ones, fine, be it so; BUT how do I tell the setup about the new memory??


Still wondering why I bother

Thanx in advance				Thomas
