[Premium-Rx] RA6790/GM memory battery NiMH replacement

[Dan Rae]

For those who didn't already know, the supposedly leak proof drop in 
replacement Varta NiMH battery for the A6A2 cpu board is available in 
the US from Mouser, part number: 672-55615702, $6.10 in small quantities. 

I've been using various NiMH batteries for a while, mostly on little 
daughter boards, but it's nice to get the exact one...

This applies also to the early RA1792 cpu boards as well, of course, but 
most of those seem to have been fitted with the later Varta batteries 
either on daughter boards or directly on the board with the later 
revisions.  NiMH  versions of these are also available from Mouser.  
Part number 672-55615302.

Having just spent a long time cleaning up an A6A2 board, it's worth 
getting nicads out of there!
