A vintage Commodore SR-1800 Scientific Calculator (or as Commodore called it - a mini computer because of its ability to handle an extensive range of complex assignments across a broad spectrum of basic and advanced mathematics.) Serial No.16145. Made in Japan. Can also be operated by an AC adaptor (not included) but it has only been tested with batteries and is working perfectly.
In very good, condition - no scratches. Some scuffing on the back plate. Comes with original case which looks its age and is tatty. The original instruction booklet is missing its covers and the first couple of pages which only show the page content information. It has been well used with small age marks and very creased but still legible.
