RE: NEW: HP 15C Collectors Edition
Received mine in Asia yesterday.
I tested the calculation speed of an inverse of a 4x4 matrix. It gave result almost instantly. All keys gave good responses except the "8" & "9" sometime registered twice. I need to keep an eye on the display and press the back-space key when it takes place. the s/n of mine is 01054 12C, 15C, 15cCE, 19Bii, 20S, 22S, 35S, 39Gii, 42S, 48G, 50G, 97 |
