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.

In comparision with the TI-30 family this calculator uses a slightly different chip:

• TMC0980    Goulds Pumpulator uses a custom design ROM (CD9801)
• TMC0981    TI-30 and SR-40
 
• TMC0982    Business Analyst and TI-41
• TMC0983    Programmer
• TMC0984    TI-33

• TMC0985    Amelia Scientific 2001

The main difference between the Scientific 2001 and the TI-30 is the lack of the AOS entry that allowed up to three pending operations within the parantheses. On the other hand it got the x! function missed on the TI products.
