I have upgraded my Mac Plus to 2.5 meg, by adding 2 1 meg 100ns SIMMS.
I am running sys 6.01 with a 45 mg Rodime drive. 
The computer starts OK from a cold start but often crashes with system error 
02 or just hangs. When restarting with the programmers switch or from the
menu bar the computer often displays a sad mac with code f0002 (this is
an address error).
I have tried re-installing the SIMMS with no change.
Is this a hardware or software (system) problem??
Has anyone else had this problem ?
Any help appreciated.
