Guys, need to verify, I am trying to get an Indigo R3K back online....so far, I was able to get the PSU working, but now it doesn’t detect the keyboard. I know is not a PS2, but I have an adapter. If someone can take couple of measurement. Pin4 of the Keyboard connector I know is 8v and Pin6 must be around -8v but I am getting -4v, can someone confirm.... I think that the previous owner plugin a PS2 Keyboard and damage it. I fallow the schematics pin 6 ends in Pin 8 of the U44 (SN74LS125AM). From U44 it continue to the DSP Pin 28 (TXD). the DSP U32 control the SCSI. Any feedback will be appreciated.
