Just saw it in the news:

That was a fascinating little something, I think.
I would have liked it in the 90s, I believe.

That tone-dial system, especially.
It uses DTMF, I guess. In my place, we were still used to pulse dial at the time.
While our corded phone had buttons already, we had set the slider to impulse dialing.
My father had on of these cool little gadgets for answering machines. A little hand sender that had a rubber keypad with numbers, # and *.

Anyway, the WorkBoy never made it because the DRAM prices increased, making the device unattractive.
That's something I vaguely remember, ; it also makes sense now as to why Win95 got an unreal 4MB minimum memory requirement.
The DRAM crisis must have taken place between 1992 and late 90s.
I'd wish I knew more of it.
