While not much about it electrically is all that interesting, it uses the wonderful magnetic reed switches for registering key presses. It’s not tactile in any way, but they feel solid and will last an extremely long time. It’s a fairly standard adding machine style calculator with a VFD. It had the nice features of choosing where the floating point is and giving you a storage register to preserve a value.

Notes
I picked up this E variant because it came with the dust cover and carry case I didn’t have before. As far as I can tell, this is functionally identical to the 121-L I did a video on a long time ago. Also at this time it’s disgustingly filthy with cigarette residue all over it and needs a full tear down cleaning. Some day…
