2mm thick 8-bit computer

And that includes the display & keyboard!

Reminds me of a Casio mini computer/smart calculator...

 

More impressive if the display was full monochrome dot matrix with a decent refresh rate, and a small peizo speaker...

 

Does it have any GPIOs to slap such a thing on?

I still dont see good data on it... but under his thumb, that appears to be an exposed data bus? Maybe with a select logic pin, to serialize address bus?  (eg, pin 9 raised means 'address bus', and pin 9 low, means 'data bus', so serialized address, then data, for a full IO op?)

 

OK, looks like this is actually 5 bit?

Or at least, only 5 bits are exposed in the expansion bus area...  The others are mclr, ctrl, VCC, and pals. Means driving a sound chip will be dodgy.

Seems to have few parts.  I wonder how hard it is to put together.

 

Miss the days of portable organizers with weeks worth of battery life.

I would be more interested in say, using PragmatIC's "Plastic IC" foundry service, to straight up just have plastic based smart credit cards made.  Should be quite amenable to eINK ePaper displays.

They recently had a breakthrough with getting ARM M0 reference designs fully working at >1cent/unit with bulk manufacture.  Since they do bespoke work too, according to their site, a "Self-designed" 8 bit CPU on plastic substrate should be achievable.

 

Say, something that has a 'coin holder' to accept a penny into, that you then just get wet-- to supply wet-cell power with.

Thanks @wierd_w, he hadn't posted that page yet when I ran across the tweets yesterday. Looks like he tweeted the hackaday link about 4 hours ago.
