PACE TR-20 / TR-48 Desk Top Analog Computers

A six-page color sales brochure from Electronic Associates, Inc. (EAI) promoting the PACE TR-20 and TR-48 desk-top analog computers. The TR-48 features up to 48 amplifiers, the widest usable bandwidth of any desktop computer, high-speed repetitive operation (100 to 5000:1 time-scale change), solid-state readout, removable color-coded patch panels, and low-power compact design operating from 115/230 V at 50/60 Hz. The TR-20 is a portable fully transistorized 15" x 27" unit with up to 20 amplifiers, interchangeable non-linear computing components, variable diode-function generators, and an inclined color-coded patch panel; typical applications listed for both machines span aerospace guidance, nuclear reactor simulation, chemical kinetics, biomedical modeling, and geophysical analysis.

Color-coded by function; Modular; Bottle plugs for 70% of patching; ALL necessary terminations brought to front panel for complete storage of prob'ems (including mode control relays, additional X10 time scale changes, inputs, outputs, etc.). ™ COMPACT AND MOBILE, LOW POWER DRAIN — sets on any desk and plugs into any 115/230V, 50-60 cps outlet. Power drain less than a 150 watt bulb. The most complete desk-top analog computer available — solving sophisticated problems such as those requiring high-speed repetitive operation and iterative techniques with a capability equal to that of many console computing systems. The TR-48 is solid-state designed for long-life reliability — an expansion of the successful TR-10 com- puter, the first completely transistorized analog computer. The TR-48 is available in any complexity, from a basic unit to simulate linear systems to a unit to provide the most complicated non-linear simulations All computing components plug in from the front for simplified system set-up, regardless of complexity. TR-48 computers are readily “ganged” and “slaved” for even greater extension of system capabilities. Typical applications of the TR-48 are: system optimization, boundary value problems, model building — including portions of the anatomy for bio-medical investigations, rapid determination of stability of control systems, approximate computation and display of integral transforms, statistical studies requiring many solutions, and a wide variety of routine computational problems requiring multiple solutions. Every operational feature of the TR-48 is human-engineered to the maximum to simplify operational training and the actual programming. Your present engineering perscnnel can learn to operate and program it without elaborate training, and discover the multiple benefits in shortcutting time to solution of their most intriguing problems while cutting cost in the engineering of optimum products.

The PACE TR-20, is an all-transistorized desk-top analog computer that puts proven high-speed computation at the engineer’s finger-tips. Though compact in size it is a full fledged computer, capable of solving many complex problems previously requiring scheduling on large computing systems. It offers up to 20 amplifiers plus components for addition, subtraction, multiplication, division, integration and generation of powers, roots, logs, antilogs, sine, cosine and arbitrary func- tions — in one cabinet, and available to one patch panel. The TR-20 is useful in solving problems in such diverse areas as servo-system design, heat flow, chemical reaction analyses, suspension systems studies and many other problems involving dynamic conditions. With a TR-20 analog computer an engineer can explore problems as they occur with instantaneous visual readout — determining the feasibility of projects immediately — without leaving the desk. Simply turn a dial to feed in parameters, and the computer provides an instant, dynamic picture of the effect of each change. The endless drudgery of step-by-step calculation is eliminated —engineering data becomes alive. solution of 5 degrees of freedom equations in submarine control. problem # simulation of interior ballistics of a cartridge-actuated device simulation of the primary loop of a nuclear power plant @ poi- _ sonimetry studies analysis of flow path of an oil globule M™ cross correlation of ‘seismic traces determination of electro-osmosis in soil analysis of treating plant waste-disposal system Analog Simulation... Pace TR-20 and TR-48 Computers WTOUULE See ae Analog Simulation is a dynamic method of solving the problems that confront the engineer and scientist daily — and EAl TR-20 and TR-48 Analog Computers provide an unsurpassed capability for simulating systems of all types. Analog computers help slash project costs by saving time and cost of materials in trial and error testing of prototypes or pilot plants. One engineer with a desk-top PACE® computer can be the equal of several men limited to conventional design tools; moreover, he can gain a unique insight of the dynamic performance of systems to produce a superior product. Experimentation time and costs are similarly slashed. Ideas that were once too costly or time consuming to be tried can be “debugged” right on the computer. Analog computation actually stimulates creativity. @ High dynamic accuracy over the widest range of frequencies available in a desk-top computer. @ Excellent combination of real-time solutions and high-speed repetitive operation. Change from real-time to HSRO (500:1 time-scale change) is accomplished without program patching changes. Units offer fastest repetitive cycling rate available in desk-top computers. @ Fully transistorized design is field-proven (over 600 units in the field) for: Extremely high reliability ll Ruggedness Mf Compactness M Low drift — non-heating components MM Cool operation — no need for air-conditioning @ Insensitive to ambient temperature (35 to 120° F) Ml Low power — plugs into any wall socket. m Complete line of computing components compatible with high-speed amplifier and best dynamic accuracy of any desk-top computer. @ Ultimate in progamming ease and problem control developed over years of engineering experience on larger analog computers.
