I knew I had one laying around somewhere. So, I dug it out of a storage bin. The batteries had corroded in it a little. Once I cleaned the contacts some (could use a little more work), I was able to reinstall the survey program and everything seems to work.
I wouldn't mind keeping it, but I never actually use it any more. So it might as well go to someone who might make use of it and raise some money for an awesome website.
There is no shortcut overlay on it and I could not find one. I looked and it appears you can get them off eBay for around $20 or you could just use the menu function keys. Some of you may have enough muscle memory that you recall the important shortcut keys.
There is no manual to go with it. I looked and could not find it.
Since I roughly know the shipping costs, if anyone is interested and wins the bidding, I'll ship via UPS ground in the continental U.S.A. Outside the lower 48, we'll have to determine the shipping amount to see how much higher it would be as it goes up pretty quickly once you get out of that area.
No guarantees on how it will hold up in future as it is probably at least a 20 year old calculator!
When I previewed the post, it looks like clicking the picture will allow you to cycle through the three pics posted. One of which shows the battery compartment in case that concerns you.
