... Well, that's a new one to me. Never heard of that at all. Guessing tms1000 based but god knows.
That's made by Selchow & Righter, same ones that made this:

I think I still have a Readers Digest, I'll see if I can find it...
That also reminds me of Monty Plays Scrabble:

Don't think that's in MESS... It's actually Z80 based with normal PROM/EPROMS. I've dumped the ROMs (links on my page), I can send one to someone if they need the harsware to emulate it...
