Hello!
I have an EIII that I received from someone who thought it was a keyboard. The guy's girlfriend's brother had it when he was younger is what I heard.
Anyway, when you plug it in it reads: "EMULATOR III, ?1988 E-mu Systems, Firmware: v1.00, Checking Floppy..." And then SCSI 1-7.
So it runs, but that's all I know. It has a double foot pedal, a power cord, and an old set of head-phones with it. I'll try to add pictures, but the forum was being persnickety.
Edit: I should add, I'm located in the Bay Area, California.
Oh, and the plastic part of one of the sliders is missing.
Edit:
Thanks for the interest; the item has been sold.
