The Perfoma 200 is a Classic II; which has 4megs on the mother board. The RAM on the SIMM slots is supposed to take it to 10megs at most (2 more 4Megs will take it to 12Megs which 2megs it is blind too).just tell me what can I do with the SIMMS chips.. what can i replace them to ? I have a real feeling, it is them SIMMS chips whats causing the issue.
See the link attached.. These are the ROM/SIMMS CHIPS i am talking about which i am sure are the problem..

Performas come with their System 7 that says Performa on "About this Mac." The issues here is the system end in a "P" like System 7.0.1P in the Performa 400. But if the system crashes and you reinstall a system from a Generic CD or Floppies, the "About this Mac" come up with the Non-Performa machine version; that Performa 400 I stated before becomes an LC II.(I'm fairly certain it comes up as a Classic II on the System 7 versions that identify the particular machine in "About This Mac")
