|HP-12C Clone, New?|

I don't think this has been discussed here before...
I came across another HP-12C clone calculator on the web -- not the
Victor V12 nor the Aurora FN1000 -- the Compucessory CCS 28956.
Functionally it's a modified version of the code used in the earliest
version of the HP-12C Platinum. It has RPN/ALG, parenthesis, undo,
and 400 program steps but only 31 cash flow registers. It adds a
Cost/Sell/Margin subsystem complete with dedicated annunciators on
the display. The key layout is completely different than the 12C but
the unsifted/shifted function bindings are identical, with the new
functions making use of non-designated shifted keys on the 12CP.
It comes in a hinged, clamshell case, which is sort of nifty but
cheap. While the display is pretty large and readable with adjustable
contrast, the decimal points and commas are tiny. But the real
problem with this machine are the tiny keys making the overall
ergonomics of this calculator simply horrible. The manual at first
blush looks complete if brief but it omits much of the functionality
that's actually in the the firmware (like storage register arithmetic).
It runs off of one CR2032 cell and it's pretty fast. About 4.5 times
faster than the 12CP Anniversary edition. The best part about this is
that it sells for about $20 (shipping included) on many websites.
Here's are some pictures of it:
Most of the firmware in this machine is apparently taken directly form
the 12CP since it has the standard built-in tests, which are
undocumented. The keyboard test requires that you press the keys in
the same order as they appear on a 12C which has no relationship to
the layout on this calculator. If you do that this display
ends by showing "12" in the middle of it!
Cyrille and Tim, did you know about this machine?
