Such a resistor will affect rise and fall times though. On example where people overloaded an NMOS driver were the external 16KB memory expansions for the C16/C116. You cannot disable the internal RAM on these systems in a clean way from a card in the expansion port. What you CAN do is to brute force /CAS to HIGH. Of course, that will overload the output driver in TED. Gerrit Message was sent through the cbm-hackers mailing listReceived on 2017-04-22 21:01:46
