     HELP!!!      HELP!!!      HELP!!!

I screwed it up! I had 4 256 Kbyte Ram chips for a MacPlus and 
4 256 Kbyte Ram chis for a Mac II. But I kept them in the same 
place and now I can't tell them apart. Can you tell me which one
is which?

Set #1 says:

     -12 TIH8817C9SN
     TMS 4256FMC Singapore E
     TM4256HU8
     -12L 8817 SNK N4V0

Set #2 says:

     MH25608J -15
     Japan 63410T
     M5M4256J
     63235A -15

Would the real Mac II RAM please step forward?

Please Email answer! 10^6 thanks!
