Details:

Missing the power cord. It does not work correctly though. Some dripped residue inside by the rear corner of power supply area.

So this would need restoration to be back original specs. No power cord. I look forward to doing business with you. Made in japan.

Good for your collection. The ones that did respond not register the correct number on display. See lots of photos what you are getting. From a local estate.

Serial 2002 13. Especially heavy in the grooves. Includes the calculator seen above. A pretty scarce item.

Good overall otherwise. Used items are sold as is. Handle is stiff to pull out and has some residue staining. Most of the keys do not respond when pushed.

I took a peek inside and the electronics look solid overall with dirt residue some corrosion in places. Some scratches scrapes in places. Nothing else is included. Operationally I applied power to the rear pins and it does up.
