This HP 70 is a fairly difficult calculator to find in good working condition. It is a business calculator that Hewlett Packard offered as a lower end choice to the HP 80. As you can see it has a unique color scheme with the orange keys and green/gray case. It also does not have a shift key and the "Save" button was relabeled to "Enter". The HP 80 has two memory positions entered with the STO key followed by either the K or M buttons. The HP 70 lasted only a short time on the market, hence its relative scarcity, and was supplanted just a year later by the HP 22 which had more features and was cheaper.
Introduced in 1974 the HP 70 utilizes a LED display and RPN logic. The top row of buttons are time value of money functions and it has 2 memory registers. There was memory storage addition to the M register but not the K register.
As mentioned above the HP 70 was not on the market for very long which translates into few units produced and even fewer remaining today. So, collectors will pay a high price for it. Sales in the $300-$400 range are not uncommon and can go higher if the condition is excellent and all accessories are included.
