MacWarehouse floppy disk calculator

[mtbdudex]

Cleaning out my work desk I found an ancient relic that reminded me of truly simpler times.
Anybody else still have 1 of these?

MacWarehouse floppy disk calculator , circia late 1980's or early 1990's, dunno.
Anybody know when these were offered?
I looked on the back and no date molded in the plastic

Back side

Never seen one before, but they're kind cool.

On looking for more info, I've come across these:

Apple:

Commodore:

Microsoft:

The IBM one also comes with a "solutions for the 90's" imprint, so maybe that helps (very little) to date it.

I totally had (have???) one of those from MacWarehouse. I wonder where it went??? It's probably buried in a box somewhere leftover from a move. As a kid I thought it was the coolest!

On eBay there is a very similar one dated 1988

Definitely cool. I reckon the packaged 'User Manuel' must increase it's scarcity factor and hence price.
