The HP-34C is a programmable, advanced scientific calculator. Introduced in 1979, it was the first calculator to perform root finding and numerical integration. 

It features:

• Continuous memory, allowing programs and data to be remembered by the calculator - even when the power switch is off.
• Automatic memory allocation: the basic 70 lines of program memory plus 21 storage registers reallocates in 7-line increments to as many as 210 lines of program memory plus one storage register - automatically - as needed.
• Fully merged prefix and function keys that mean more programming power per line.
• Easy-to-use editing features for correcting and modifying programs.
• Conditional and unconditional branching.
• Six levels of subroutines, four flags, twelve easily accessed and reusable labels.
• Direct or indirect storage, recall, branching, and subroutine calls.
• Powerful root-finding and numerical integration operations.
