You
are familiar with this Amelia Scientific 2001 calculator? You
are right, this calculator - and its twins - are a nearly perfect copy of the
TI-30. Another target of the copy
cats was the TI-1250, don't miss the Bohsei
3000.
By comparison with the TI-30 family, this calculator uses a slightly different chip:
|
• TMC0980
Goulds
Pumpulator uses a custom design ROM (CD9801) • TMC0985 Amelia Scientific 2001 |
The main difference between the Scientific 2001 and the TI-30
is the lack of the
Algebraic Operating
System (AOS™) logic that allowed up to three pending operations within the parenthesis. On the
other hand it got the x! function missed on the TI products.
AOS™ is a trademark
of Texas Instruments.
