This
TI-30 was manufactured in Brazil and looks at first
glance identical with the US-manufactured models. The
backside of the calculator sports just a small sticker with the serial number
and country of origin and a Date code with
"CIB" for Texas Instrumentos Eletrônicos do Brasil Ltda. -
Campinas. Later Texas Instruments calculators sold in Brazil like the SR-40
LCD were assembled by Indústrias
Gerais da Amazonia S.A..
Dismantling
the TI-30 reveals a well known internal construction but the single-chip
calculator circuits sports a very uncommon designation JP0981. It is probably
identical with the TMC0981 found in the US built TI-30.
Don't miss the Money Manager manufactured in
Brazil, too.
