Nostalgia help!

Me and a buddy are going nuts trying to remember what this device/system/toy was called.

Came out between 1980-82.
Somewhat resembled a modern chromebook from what i remember, except smaller. Used tiny micro cartridges - way smaller than the Atari ones. Screen was a tiny rectangular LCD.

I know it's a longshot, was hoping it rings a bell for someone on here.

We were taking a trip down memory lane on the gaming systems and computers we'd owned as kids, and I remembered this odd one. Might have been more of an educational gadget than gaming system though.

Lots of memories here.
