Hi All...

>From a bit of searching, I gather that sticking a 62256 into a standard
master cartridge should "just work" to make it sideways RAM...

Has anybody got a simple circuit to battery back-up this?  Something I can
throw together with bits from my junk box?  I seem to recall a circuit for
the B many years ago, but I can't find it now... I'm assuming something
similar would work on the Master...

Cheers!
