Some text from a Brochure:
BUSICOM: 141DA has a wide application range with 14 digit capacity and one memory.
This is the last word in business use:
We are now able to offer this BUSICOM: 14DA most suitable for business use based on the result of our sister machines, mini-computer BUSICOM: 207 and BUSICOM 162, 162C for business and scientific use.
Operation is extremely simple:
Being equipped with rational keyboard arrangement and easily understandable key function its operation is extremely simple, anybody can be a veteran in one day.
A new system for rounding up the integral number part has been adopted:
It became possible to round up not only indicated digit below decimal point but the indicated digit of the inegral number. This is a great contribution to business calculation. BUSICOM: 141DA is the only machine equipped with these characteristics.
No more misreading due to an epochal display system:
The newest mosaic type display is used. Unnecessary zero is displayed in half-size. Because punctuation is automatically displayed in 3 digit groupings, misreading seldom happens even in many digit numbers.
Light weight and compact type make it possible to be conveniently carried:
