#157472 - Update Responding to: ???'s previous message |
OK, I didn't have much time last night, but (1) yeah, the cap should go to +V [red face], and (2) It's still not working.
The oscillator pins osculate (!) and the ALE is ALE-ing. My next test will be to plug the uC into an old debugger board I have which uses an 8032, and see what happens then. I've also checked the address & data lines on the EPROM, and they are doing their thing also. Maybe I'll try a test to exercise ALL the I/O pins, just in case P3 is blown... --Rich |
