Apple Mac Performa 5260/120 does not turn on.

https://www.optimumgeeksupport.com/apple-support

The Apple Performa has a VGA video output, so any monitor with that has a VGA input/cable with it will work fine. You can find these monitors at places like Best Buy, Tiger Direct, New Egg, etc.

The only question left is how much are you looking to spend on a monitor.

Hope this helps!

Hello, I had the same problem.
The thing is the printer is compatible with the mac the scanner isnt.
Pretty dumb but sadly true.

Hope this helps you!!

As I recall, this is a SCSI device. Like many electrical connectors, SCSI connectors can develop a light corrosion which can keep the signals from being transmitted. The easiest way to clean such light corrosion is to shut down the Mac & power down *all* SCSI devices in the chain. Then gently unplug & replug all SCSI connectors. This will scrape off much of the corrosion & usually results in connectivity being restored. Be sure to unplug and replug the SCSI terminator attached to the last device in the SCSI chain. Restart by powering up the SCSI devices and finally restarting the Mac. Good luck!
