TI-35_ATA0480_Back.jpg (145737 Byte)This early TI-35 looks at first glance slightly different from some later models, the silver faceplate seems to be brighter. 

From much higher interest is Mike Sebastian's Calculator forensics test, it reported 9.177087103 instead of 9.177087088. We know this number from earlier calculators like the TI-30 with an internal precision of 10 digits instead the expected 11 digits!

We noticed slightly differences in the finish of the keyboard between some TI-35 calculators and added this page just for reference.
