TI-35
Texas Instruments TI-35 was a series of scientific calculators by Texas Instruments. The original TI-35 was notable for being one of Texas Instruments' first use of CMOS controller chips in their designs, and was at the time distinguished from the lower-end TI-30 line by the addition of some statistics functions.
TI-35 (1979)
It was built with the slimline design as the 1978 TI-30, but with different processor and slightly changed feature set.
It used TP0324-4N processor (CMOS variant of TMS1000 family).
The display can handle 8 digits (5 digit mantissa with a 2-digit exponent) with 11-digit internal precision.
It was manufactured in the USA.
1980
It was a version with TP0324-4NL processor, which increased accuracy.
1982
It was a version with CD4557, which increased accuracy over the TP processor.
Cosmetic updates, include silver shell and new keyboard styling.
It was manufactured in the USA.
TI-35 (1982)
It retained the 1982 styling, but used CD4557 processor.
TI-35 GALAXY (1984)
It is a horizontal variant, but the functionality was identical to the European 1984 TI-30 GALAXY.
Solar version was called TI-35 GALAXY SOLAR.[1]
TI-35 II (1984)
It is a replacement for the 1979 TI-35.
It used TP0456A or CD4557 processor.
It was originally built in Taiwan, but later in Italy and USA.
TI-35 PLUS (1986)
It added hexadecimal and octal calculations and a 10+2 display (i.e. 10 digit mantissa with a 2-digit exponent) with 12-digit internal precision.
TI-35X (1991)
The design was based on contemporary TI-68. The cosmetics were updated in 1993.
End of life
Following the update of TI-36X Solar in 1996, the TI-35 designation was discontinued after 10 years of coexisting with the TI-36 line.
