[rescue] SPARCEngine 1E and VME Memory Boards

[Richard]

Sadly they are all I have…I was working on the theory that owners of the 3/E would have upgraded to the 4/E without issue. 

Much like the 3/260 to 4/260 upgrade I did back in the day. Remove old cpu board insert new COU board, install fresh OS and keep using all the memory boards etc.
