: SunOS 5.6 (the OS component of Solaris 2.6), and SunOS 5.7 (part of
: Solaris 7) both still support all of the sun-4c machines (SS1, SS1+, SS2,
: SLC, ELC, IPC, IPX), so you should be able to get it to boot.

: Unless your SS1+ has a bootROM that's close to version 2.9 (say 2.4 and

Another gotcha here is memory. The SS1 usually came with 8 or 16 Mb 
which is not enough.

2.6 will (just) install with 16M, but will run like a dog with less
than 32M.

Solaris 7 needs a *minimum* of 32M and needs at least 64M to run
at any reasonable pace.

You really need to fill all 16 slots with 4Mb sticks to get 64Mb, which
can be rather expensive. I have an SS1 with 48Mb, it runs OK under
2.6 but was almost unuseable with 7.
