I am aware the string is reversed from the board layout and       corresponds to chip locations 13 12 11 10 9 8 7 6. I pulled two other //e out       of storage and they had bad ram also. Also this machine has no beep at startup       but the speaker does        click when.if i can get into monitor and sta c030 sta c030. Help?              I swapped RAM chips around. The screen remains the same. same lowercase p       and q -s. Is it a MMU problem? Zip chip problem?              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
