I am troubleshooting a Toshiba T3200SX that turns on, but shows nothing on screen and doesn't make any beeps or show disk activity except an initial flash of the disk activity and key lamps. In the maintenance manual, I found mention of a "Printer Port LED" that can be plugged into the parallel port and apparently will display POST codes as it tries to boot up. Has anyone heard of a such a thing?
Failing to acquire a printer port LED, I have a logging, four-channel oscilloscope. Is there any documentation on the parallel port pinout for this purpose that I could use that to determine what code would have been sent to the printer port LED using the oscilloscope?
