The TI-60 Advanced Scientific calculator is somewhat different from the other members of the second generation slanted family. If you compare it with the TI-55 III you will notice first a black instead of a silver housing and second another display.

All other slanted calculators offer you a mantissa of 8 digits and 2 exponents, the TI-60 uses 10 digits to display either the mantissa or combine 7 digits mantissa and 2 exponents. The reason is the enhanced precision of internal calculations, here you get similar performance like the TI-62 and TI-65 of the Galaxy line.

The TI-60 is one of the famous "nearly programmable" calculators, you can store up to 84 key-codes in a permanent memory shared with the storage place for the statistical calculations and user memory.

TI-60_1_PCB.jpg (25978 Byte)Inside the calculator you'll find once again the two-chip design of most slanted calculators that allowed more features compared to the slimline series. 
Instead of the two TP0456 based chips of the TI-55-II you'll find here a TP0458 Master with a TP0456 Slave chip.

The design of the TI-60 was changed in 1990 slightly, please compare the bottom line of a later TI-60:

1986:  ADVANCED SCIENTIFIC
1990:  PROGRAMMABLE SCIENTIFIC

There are no differences between the TI-60 manufactured in Italy or an US-built TI-60

If you are interested in the calculating accuracy of scientific calculators don't miss the Calculator forensics.

Like usual there is a counterpart for financial purposes, don't miss the rare BA-III calculator.

The TI-60 is featured in the Texas Instruments Incorporated bulletin CL-899 dated 1986.
