Stupid 18C question

[Lithium]

Hi there!

I have a stupid 18C question... I haven't been able to source a 18C manual, and while it works like a simplified 19BII, I can't figure out how to check the memory. On a 19B you just push the yellow key and 0, but how to do that on a 18C?

The reason I'm asking is because my 19II is pretty beat up, and I have bought a very nice 18C.

Since replacing the shell is out of question, I was thinking of simply replacing my 19B by the 18C, but the lack of mempry will probably be a problem ; I'm usually using between 1500 and 2000 bytes on the 19B, depending on equations, lists, etc, and I wonder if it will fit on the 18C (28C has barely over 1600 bytes available, hope the 18C is more toward 2K).

Any thoughts? My wife will kill me if I buy another 19BII !
