The Last Psion | Alex

I'm desperately seeking information about this chip.

It is a custom #Psion RS232 IC used in the Series 3c, codenamed CONDOR.

If you were involved in the development of the 3c or knew someone who worked for Psion around 1994-1997 who might have been involved, please get in touch.

We want to emulate this chip in #MAME so that it can be added to the existing Psion SIBO hardware #emulation.

This could also help with 3mx serial emulation.

@thelastpsion Are there enough broken 3c:s to be able to decap the chip? With the node size at that time this should be quite accessible today.

@thelastpsion I'm passingly familiar with Zig but not Objective C, what would that look like in practice?
