Thanks for all your help. I will look into buying a long torx screwdriver to open it up and clean the floppy drive. Will look into the emu.

What can you connect to and will work with the 25 pin SCSI cable? Can you connect a 1.4 MB SCSI floppy drive and will it boot off it?

Also Command Option P R was held down before switch on and has no effect neither causing the machine to reboot or to hear a second chime. Is there any way of checking the keyboard in this semi booted state?

Am I able to enter Open firmware if there is one to type something?
