Some text from a Brochure:
With this new machine, you get five registers and two memories !
BUSICOM 142-PG gives you a full range of functions and 14-digits print-out.
There is a new device for counting documents, the item counter.
Square root extraction, percentage calculation, and reciprocal calculation become simple tasks.
Independent two-word total and subtotal devices are incorporated, providing for easy-to-comprehend print-out.
With five registers and two memories, storage capacity is ample.
An input buffer memory insures that entry data cannot be dropped regardless of the entry speed.
This 'computer' is complete.
High-performance high-reliability LSI's add the finishing touch.
Features also:
Adding mode specifying decimal point position auto with two digits,
Auto printing of punctuation commas to set off print-out in groups of three digits,
Independent total and subtotal registers,
Convenient repeat function for addition and subtraction,
Single data entry followed by operation of the [+] and [-] keys yields repeat addition or subtraction,
Complete protection for values preceding overflow during addition and subtraction, as protection is also applied to multiplicands and dividends, troublesome re-entry is eliminated,
Auto locking constant key for calculations involved constants, 
Convenient auto clearing, application of power auto clears registers and memories, permitting immediate access to operating capabilities,
Two-color (black and red) print-out, eliminating reading problems.

Description 

1  

Non Add:
Use of this key allows entries (such as document numbers and dates)
to be entered without affecting calculations.

2  

Punctuation:
Print-out is demarcated in groups of 3 digits with commas,
as a means of facilitating reading of results.

3  

Subtotal:
This symbol clearly marks subtotals.

4  

Item counter:
Design provides for an accurate count of documents and arithmetic operations.

5  

Total:
This symbol clearly marks totals.

6  

Square root:
Use of this key gives square root directly.

7  

Percentage:
Use of this key gives percentages directly.

8  

Round-off (discard four - retain 5)
Results are rounded off according to the decimal part place setting,
with values of four or less discarded, and values of five or more carried.

9  

Memory 1:
Execution of multiplication and division is followed by storage of the result in this memory.

10  

Memory 2:
During multiplication, the multiplicand is stored in this memory,
at the same time, multiplication is indicated.
