Hello,
As the title describes, my beloved Mac SE is facing problems pertaining to the use of SCSI devices.
I began to suspect something was wrong when my Mac failed to recognise any SCSI drives - this includes a fully-functional BlueSCSI device and two internal SCSI hard disks.
Upon further inspection of the logic board, I found that the CR1 diode had blown; this lead me to believe someone or something had forced something that was not SCSI compatible into any one of the SCSI ports.
In an attempt to rectify the issue, I replaced the blown CR1 diode with one of approximate value. This did not work.
With one step of troubleshooting undergone, I'm beginning to think that the AM5380PC SCSI controller is fried.
Is it worth sourcing a replacement chip?
If so, what are the difficulties associated with such a task?
