Small, hex/octal/bin operations, DMS and fractional representation, polar/rectangular, one variable stats all in a small form factor. Big fun!

That was a great calc. Prior to my discovery of HPs I used this one in HS - the ole red led Ti died. I hope your post doesn't have me digging through boxes as I should still have it somewhere.

I usually keep an old Casio solar scientific in the car for "needs be".
