*What did I do in case you are interested.*

Cleaned case, no retrobright, it's already fairly nice.
Removed old battery pack and rebuilt with modern Ni-Cd, 1000mAh 1.2 cells, for much longer run time, and to last another 50 years. 
Sourced a replacement AC Adaptor, tested via meter to provide consistent steady voltage. 
Cleaned up AC Adapter, replaced front missing Brother badge, it's close, but it's a reproduction. 
No board repairs needed, no traces needed to be repairs, no acid leaks to important components. 
Burn in tested 24 hours. Ready to rock.
