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
