A "new" HP 28S

Have I ever mentioned how much I love my HP 28S?

After taking the stats course this semester, I decided it would be nice to have a second one so that I could have one at work and one to use at home. Found a few on Ebay and bid on one. Things were going well until someone came along and ran up the price to $75, but I ended up getting it.

It arrived a couple of days ago, and today I finally made it over to Radio Shack to get some fresh batteries for it. Put them in and turned it on.

Yay, it works!

It's in great shape and looks practically brand new. Even has the rubber pads still (the pads on mine disappeared long ago). Part of the casing around the battery cover has chipped away, which isn't unusual for the 28S.

From the serial number (2939A05016), it's the same vintage as my calculator (1989) made possibly a couple of months after mine was.
