Ok, I have been trying to figure these out for months.... On the off chance that someone here has seen, used, - heck, even designed the thing - I'm turning to you all for some expertise.

I have over 500, maybe as many as 3000 of these, in a mystery storage unit I bought out a few months ago.

The Windbond chip is a 12ns 128k CMOS memory chip.
Link2

That's the only thing I've been able to find out.

The PCB is marked KUO_04719B - no hits on teh google.
There is the sub-module marked TT005 - again with teh google - nothing of any use.


If no one can jump in with the answer I'd be happy to make them available to anyone who would like to fidget with them and see what they are - just let me know if you find out. If they're worth anything I'll hook you up nice :)

Thanks guys and good luck :)

It looks like a LCD with that sort of protective cover. The cover protects it from dust and scratches.

you mean an LCD controller, right?

The tape marked TOP is on 90% of them.... the underlying board has no liquid crystal displays on it AFAIK. the 2 black spots are epoxy.

60 pin card edge, weird.
NES games are 72, and ISA bus is 62, IIRC

chip on board, and nasty hand soldered SMTs...

i bet it's a part of some toy.

That would make sense as they were found with about 10,000 imported chinese knockoffs of popular electronic games.

btw anyone want a DDR knock off mat?

One of the blob array chips looks like it might be an ISDxxxx clone, in which case it could be useful.

(single chip voice recorder)

Might be worth doing some quick tests and see if the pins correspond to power etc
