Sharp EL-506A  Scientific Calculator with case and manual - works great.  Looks to be in VERY GOOD CONDITION. Also includes the 132 page book Conquering the Sciences - with applications for the Sharp EL-506A.

I have several other vintage calculators that I am listing - check my seller's page.

I am always happy to combine shipping on multiple purchases.  If you purchase more than one item, please wait for an invoice from me that reflects combined shipping.

Thanks,  Roger
