Non parity 72pin SIMMs are 32 bits wide. Parity are 36 bits wide.
Thats where that 4/36 comes from. Only 4/36 bigger for parity.

What did you do price wise, just ask him ?  Or tell him about
Johns $165 class price and see what he had to say about that ?

I still think you should be publicly whipped for conspicuous consumption.
