“This unit is in excellent condition for a piece of equipment this age. Probably just needs a little dusting and you’re good to go. As with any vintage music/audio equipment you’ll want to treat it with care. Some EX-800 units have been known to have a leaky battery that can be a problem, but as shown in the photos, the battery in this unit appears to be in good shape (and I believe it is the original, unless the previous owner changed it out, which is unlikely).
This listing includes the EX-800 unit only. Does NOT include power cord, so you’ll need to have or get a 9-volt power supply with “center pin negative”. You can buy adjustable voltage power supplies online, but get one that outputs a reliable voltage, as any vintage synth like this can sometimes behave oddly if the power is not at the correct voltage (such as making buzzes, or clicks, or not loading program data reliably).
I do not have the EX-800 manual or any additional paperwork. You can probably find that documentation online if you need it.”
