This is a vintage early computer from Beckman Instruments and is the Electrocomp Electric Heating Computer. I don't know the exact date of it and the internet shows that it may be from the 60s and it was used by heating salesmen with heating calculations. It powers on and runs smoothly and quietly on both settings on the power control and the top VU Meter needle moves as it should on both settings and I show it powered on. It is in great condition with no scratches or marks on the top deck and it is still nice and white. The power control knob does have cracks in it and still moves and turns fine. The briefcase cabinet material is also clean with some scuffs and scratches on the covering and the latches lock down as they should. Includes the Operating & Calibrating manuals and both pieces are in very clean shape as well. The computer measures 17" by 13" by 4 1/2" and weighs in at 8 1/2 lbs. I show a number of photos and it will be packed well and shipped right out.
