The
TI-65 Technical Analyst is a quite interesting calculator
within the Galaxy-line. In addition to the functions of e.g. a TI-37
Galaxy it adds both programmability and a timer function. The resolution of
the timer is one second, the maximum time before an overflow occurs about 40
hours.
From the technology this calculator is a mixture:
 | Housing similar to the Galaxy |
| Keys like the later TI-68 |
| Calculator chips from TI, not Toshiba |
Compare this calculator with the silver TI-62
Galaxy.
