[rescue] SPARCstation 1 boot woes

[Ethan Hawke]

I don't currently have plans as I quickly modified another project so 
it's a bit of a mess, I may refactor it in the future for release.

It works pretty much as expected, it just maps the PROM in from the 
physical address based on the model/series selected, checks for the size 
and then sends it over XMODEM.

If there is anything specific you are interested in, let me know!

Cheers,
Ethan
