Hello, we have a Sharnoa SDC20 machine with the Tiger 4 control unit. Upon startup, just after the screen displays “Sharnoa Electronics”, the error message, “Error at PC# 7DFE, IOB: 752A” appears. We have already attempted replacing the floppy drive, and replacing the floppy disk to boot from, as well as many of the cards within the computer including SE300-1, SE179k, SE148k, SE148k, SE136k, SE63. We do not have a manual for this machine anymore, and are unaware of what the error message is exactly stating.

Does anyone know which component(s) are being identified by the message, “Error at PC# 7DFE, IOB: 752A”, or what could cause such an error, any input is appreciated!

-Thanks!
