Info: The 325 does trig and algebra and handles calculations with up to four levels of parenthesis. Programs are accepted from tape in 416 step increments and the unit features 12 data registers,
a two-color printer and 12 digit display.
Computation is 13 digits with a range of 10^-98 to 10^99. His little 326 brother has no printer and holds 160 rather than 416 steps.
Both units include 13-digit capability plus program commands for branch, six subroutine levels and seven conditional statements.
Also edit operations such as verify, insert, delete or modify are easily done on the keyboard. As a bonus, the 325 will interface directly to a TTY.

Programs and Data Are Stored on a Tape Cassette:
All arithmetic operations are performed algebraically, just as they're written on paper.
Plus parentheses four levels deep. It has both a printer and display, yet it takes up less room on desk than the average in-basket.
A magnetic tape drive is included to allow users to read programs or data into the 325. The tape drive can as easily receive programs or data from the 325 and record them for future use.
And a user's entire program library can be stored as a unit since a cassette holds over 150.000 program steps or 4.000 data values.
Programmable from the keyboard, the 325 also automatically accepts blocks of programs from tape in 416 step increments.
Under program controls, users can call another program and store or recall data from tape. Besides providing a permanent record of computations, the printer is also handy for listing program steps and data values,
and for editing and verifying programs.

Over 100 Pre-Programmed Operations:
To save program memory and make calculations easier, over 100 preprogrammed operations for logarithms, trigonometry, statistics and even 24 metric conversions are hard-wired into the unit.
For example, users can perform trigonometric functions with a keystroke, determine the standard deviation of a sample of grouped or ungrouped data, and convert kilograms per square centimeter to pounds per square inch.
For all trigonometric functions, the 325 works in degrees, grads, radians and degrees, minutes and seconds.
All arithmetic operations can be performed using degrees, minutes and seconds (or hours, minutes and seconds) with the results formatted, 11 28 33 6000 ; the printer formats 11 28 33.6

Programming Is as Easy as Working from the Keyboard:
Programming is a simple extension of the 325's basic mathematical operation. Users enter computations in load mode just as they would calculate it in run mode when solving the problem from the keyboard.
They switch back to run and simply enter the variables. Ease of use extends beyond elementary programming. Program editing has been made extremely easy.
Users can move back and forth in memory, verifying, inserting, deleting or modifying any number of program steps.
They can even step through a program to watch its execution one step at a time. Or they can automatically list the entire program.
The printer provides a permanent record of all steps entered, with step number codes and mnemonics.
Jumping, branching, six levels of subroutines, labeled addressing and seven conditional statements for testing are all standard features.
In addition, COMPUCORP has written program packs for a wide range of applications.
