datasheets search for XC68704P2S & JMA5416PLACA

[delo]

I found the chips in the subject and can't found any datasheet in
the internet...
The motorola XC68704P2S is a 28 pin cerdip quartz window.
I found only 68705...
The other chip is JMA5416PLACA is a 20 pin 300mils plastic dip
with the letters (under the logo ) G P S, what the name of the fab??

TIA

The Motorola part is an engineering sample / prototype (devices
numbered XC rather than MC are prototypes). The device you have is a
microcontroller with onboard EPROM (the window is for erasing that
eprom), and is no longer even referenced on the Freescale website
(which is what Motorola SPS was until it was spun off). I would guess
it was dropped a long time ago - the entire non-HC family was
end-of-lifed or given planned obsolescence a long time ago except for
some part being used in high volume in legacy applications.

Can't help (right now) on the other part.
