Hi

 

I have lost my record of the PSU motherboard connectors for my BBC B+ before
getting this recapped.

 

I've looked at pictures but are still not 100% certain as most of these are
not at the angle required. Has anyone a clear picture of this board?

 

I have also lost my chip from IC68 which I suspect is why it went from 64k
to 32k (sic). This was during an attempt to fit GOMMC.

 

I did consult my BBC concise service manual but found the schematics not
that clear.

 

Presumably there is an easier way to go to 128k to  these days without using
the R/H side daughterboard? Just wondering.

 

Any help appreciated.

 

Thanks

 

 

John
