At a time when computers were big, heavy, electrically-scented, hot and expensive (ranging into the hundreds of thousands of 1953 dollars, many millions in 2010 bucks), and coming at a time when very few individual companies (exterior to the military/industrial sphere or insurance) actually owned one of these machines, Lawrence Wainwright wrote a useful guide to potential computer-buyers, “Digital Computer Questionnaire”. Appearing in the world’s first publicly-published computation/computer journal, Computers and Automation, Wainwright sets out in six single-spaced pages a very tight and logical set of questions for the would-be buyer of one of these early god-sent beasties. I've illustrated the non-illustrated questionnaire with a series of images from another article found a little deeper in the same journal, "A Pictorial Introduction to Computers", which appeared in June, 1957.
The
questions are excellent—they are just old, and no longer applicable, much like
our own will soon be.
Digital
computer Questionnaire
General
Are instructions and data interchangeably stored in all memories?
Is internal operation binary, decimal, or what?
Memory
What are the types and sizes of intermediate memory (magnetic drum or equivalent)?
What are the type and size of slow memory…?
Abnormal Operation
What are indicators and effects (Machine stops, record is made, etc.) of faulty action by the operator, program error or defective data?
What is its defining characteristic?
What is its form (cards, tape, etc.)?
What are the compiling routines available?
What is the reduction factor in operating speed?
If programming is limited, to how many steps?
What are diagrams and descriptions of controls, indicators, monitor devices, program progress counter, etc. for computer, input-output means, and operating auxiliaries? What are the flow charts for instructions, data, indicators, etc.?
What is the description of magnetic tape units?
If cathode-ray tubesa re used, what are constructional and operational details?
If magnetic flip-flop or equivalent storage is used?
If magnetic drum is used, what are the specifications as to construction and operations?
What are the requirements for maintenance personnel to number (shifts), education, training?
How many operators are required (for 1, 2 or 3 shifts)?
How many proposed installations have been made?
What is the plan of the floor space required for all units…?
Have any acceptance tests of any part or whole of the proposed installation…been held?
What are floor and elevation plans with dimensions, weights, power requirements, cabling and ductwork requirements (including under-floor and special overhead spaces)?
What are types of tubes, crystal diodes and similar critical items?
To what extent have chassis sections or similar sections be standardized?
