- Description
- This lightweight, non-printing electronic calculator has an array of nine digit keys at the center with a zero bar and a decimal point key below these. On the right are arithmetic and clear keys. On the left are percentage, percent change, gross profit margin, item count, clear memory, recall memory, memory subtraction, and memory addition keys. A switch between a floating and a fixed decimal point, a constant switch, and a power switch are above the keyboard. Behind is a ten-digit vacuum fluorescent diode display. A cabinet has space for two D batteries. A jack for a cord is at the back, but there is no cord.
- A mark on the front of the machine reads: Lloyd’s Accumatic 680. A label on the back reads in part: LLOYD’S (/) Model No. E680-3 (/) Series: 260A. It also reads in part MADE IN TAIWAN. The interior of the calculator has a single circuit board which has a mark on the bottom that reads: 5212232. A mark on the top of the circuit board reads: CA2486-03 K1. The chip by Texas Instruments has a mark that reads: TMC1073NL (/) KSLP 7736. The “7736” indicates that the chip was made in the 36th week of 1977.
