Calculators: Handheld: Sharp Elsimate 8016S

		Size (approx):	72mm x 128.5mm x 20mm (w,h,d) Weight 112g excluding batteries, 145g including.
		Power:	3V DC with 2 x AA batteries. Rated at 0.5W. Also accepts adaptor EA-17E or rechargeable battery pack EA-18B. Socket is on top side on the left. Stated operating time of 8 hours on manganese batteries. The on/off switch is on the left hand side in line with the Sharp logo.
		Case:	Two piece plastic case with a base in smooth white and a top section in matt black. A metallic display surround is printed black and red with the make and model number and designer stripes. The green display filter is flat and slightly raised. It gives a clear bright display. The keys are medium travel with a very squishy action but work well. Oddly looks like a key is missing as there is a slight depression underneath the (2) key.
		Display:	8 digit green VFD (ninth right-most used for minus and error flag)
		Features:	4 standard functions with percentages.
		Age:	1976
		Manufacturer:	Sharp Corporation. Made in Japan. Serial No. 62192304 (and also own 66251512) from label in battery compartment and on box.
		Comments:	Nice compact, heavy calculator with basic functions. The on/off switch at perfect thumb position on the upper left and side. The logic is sound though the lack of recovery is annoying. Typical of this era in design for Sharp. Bright clear VFD display helps but the metal surround is prone to scratching with all that painted design. Original case is black leatherette, open top with embossed "Sharp" on the front and "Made in Japan" on the back. Very similar to the earlier EL-8016.

Components:	1 x cpu; Hitachi HD36360S 6B 13 (date code February 1976), 28 pin 0.6" width black plastic 1 x 9 digit VFD unit, glass tube flat face 1 x transistor 5 x diodes 7 x capacitors 2 x resistors 2 x resistor arrays 1 x transformer
Boards:	Keyboard board is attached to the front by one screw and has ID number F1234CC. The main CPU board sits loose on top and is hinged off with connecting ribbon of stiff wire and centred using a plastic post. The ID mark is F136 2.
Construction:	Front panel can be prized away by lifting the lugs in the battery compartment and then gently separating two similar lugs at the bottom. There is a foil shield strip on the inside of the back, which is connected to the negative line.

Logic comments:	The (CE) button is used to clear last entry of a number and the (C) to clear the whole calculator.
	Overflow on number input is suppressed, keying in a ninth digit is ignored
	There is automatic constant on multiply and divide only
	An overflow error shows the result and "C" ("E" if negative) in the far right (first) digit and is not recoverable
	Divide by zero results in "0.C" and is not recoverable
	Negative numbers are flagged by a "-" sign in the far right (first) digit thereby allowing full eight digit negative numbers

Sorry no box image, I do have the box but it is too poor to scan. The box at 85mm x160mm x 34mm is the tray plus slip-case type. Box has a sticker on the left hand side with the serial number. Made in Japan.			A comprehensive, four language, 32pp two/one colour manual in a colour that matches the box very well. Notice the use of the old name "Compet" in this booklet. Printed in Japan with reference numbers "IT971<1683>".
It came with a Guarantee Card which, oddly, is wider than the box, so must have been supplied separately. It measures 125mm x 88mm and is four-sided (fold over) card printed black and red. It gives two addresses:
Sharp Electronics (UK) Ltd. 107, Hulme Lane Manchester M10 8HL		Sharp Electronics (UK) Ltd. 357, Uxbridge Road Southall, Middlesex
It also came with a "Sharp ElSI MATE International Warranty System" which outlines conditions and lists all world wide contact details. It measures 260mm x 96mm and and is folded twice to compress it. Printed in one-colour dark blue.
