CASIO
I am interested in collecting old calculators, which you can read about here.
Other things I'm looking for are listed here.

For Slashdot readers:

The CM-100 calculator is pictured about a quarter of the way down this page.

Regarding manuals:

Casio has a number of manuals available for download here, although many of their older ("vintage") models are not online.

I found this note but have not verified the phone number or the service:

Re: Getting a manual for Casio FX-19

From: Frank Travis

Casio Document Center has manuals (else copies of manuals) for all Casio calculators (even ones no longer made). Their phone number is (973) 252-7570. They sent me Xerox copies of the user's manual for the CM-100 (CM standing for Computer Math) calculator made in the 1980s.

I have five of these neat early clock/calculators, three black, one white and one red (Japanese instruction label)

One of them (1767833) is missing both battery covers and another is missing the inner cover, so if anyone has a unit they wouldn't mind parting with, please let me know.

You can download the instruction manual (in PDF) by clicking here (thanks to Kathrine Wasserman for the manual scan ).
