[comp.sys.ibm.ps2.hardware] Compatability of memory chips

nef@mace.cc.purdue.edu (paulhicks) (02/22/91)

Dear fellow PS/@'ers.  I am thinking about upgrading my 55SX
from the origional 2Meg to 4Meg using a 4Meg Sim.(If anyone
knows a reliable inexpensive sourse please let me know!)
Now here's my question.  My sister has a Model 25-286 with
1Meg.  If I give her my old memory, are they compatable?
In otherwords do the 55SX and 25-286 use the same memory
chips? (My gut instinct is no, but one never knows).  I
should have looked under the hood of the 25-286, but alas
I didn't have the time :-)
Thanks, Paul
