I will try and scan in the procedure tomorrow. You have to set a write enable to completely clear mem. and enter the OP's .
and like I mentioned before the parity bit has to be entered.
It looks like the majority are messed up.
The procedure I have you clear the whole memory and re-punch everything back in.
As long as you have the original para. copy, I thought I had a sample T1 copy, but it gone.
