C103225 Rev.2

[Astal]

My board is not stock, as I have removed the shielding from the shifter circuit and there is a CPU socket installed, this is needed to install any large CPU upgrade cards such as the TF536

I've found very little documentation of this board so I figured I'd post it here, I've got an Agilent 100MHz/1GSa oscilloscope and can probe anything if needed!

Oh wow, I've not seen that one before.

@exxos It's quite a strange one! I have found very little to zero documentation on this revision, this is a US board, the soldered chips seem to have datecodes from 1987, seems like one of the last STF board revisions. Has the blitter spot as well, I'll be testing this out with the TF536 and might get a blitter and socket for it one day!

Interesting motherboard revision. Thanks for sharing. It would be nice if you could post a higher rez picture so that it would be possible to read the chip markings.

Thanks,

@ijor Sadly this is the best resolution camera I've got, Nokia isn't nearly as good as they used to be with their phones' cameras!

I'll look around and see what I can do. Eventually I'd like something nice.
