The idea isnt to block the NMI (is there a separate nmi line? I > didnt notice), but to block the parity error signal. You did not catch the point. An ISA card does not generate the NMI for parity error; the parity error is generated on the mainboard itself (that is, if the ISA card is not a memory card). So, you don't get that parity error signal. It's not a parity of the data bus or so, it's a parity of the memory. Hope that clears something, Spiro. - This message was sent through the cbm-hackers mailing list. To unsubscribe: echo unsubscribe | mail cbm-hackers-request@dot.tml.hut.fi.
