I have a heap of knowingly well working 41256 DRAM chips, that I want
to use to upgrade my 100+ to its full capacity!
The memory card excepts the chips as 4164 with switches 2+3 down and gives
me 384k Memory, but in UP-Position no workies anymore(Message 27)

Question1: What could be the problem with the card?
Question2: Are there any jumpers on the Mainboard to be set??


Thanx for any help offered out there in the world!!		Thomas
