HP Classic upgrade kit - Multi Emulator (updated list of emulated models)

HP-80 converted to Multi calculator HP-67

I want to share how I inserted my new multi calculator board into an HP-80 and converted it to an HP-67 with vinyl overlay.

On the right the original HP-80 main board


Haralds and Tonys multi calculator is so easy to install and can repair any Classic calculator (except HP-65 hardware). It consumes only 50 mA, when switched ON, depending on the display contents.

In my case the original HP-80 had a ROM code issue and couldn't calculate some functions like square root or financial functions. But I didn't want to keep the business calculator HP-80 either, so I applied an HP-67 overlay, which originally was designed for the HP-67 calculator, but fits quite well to the classic case. Only the area above the first row is not covered and the front side label is a little short.

Many thanks and respect to Tony and Harald, this is a fantastic board for repairing or upgrading the HP "Classic" calculators.
