Congradulations! I've an 11/10 that I "resurected" from parts. I'd
first try a few simple test programs. An obvious one is to write a
stream of characters to a terminal (see my website for a simple to key in program for

Having just done this on an 11/45, it is *much* easier to have it on a
pack already.

How much memory do you have on it? I had plenty on my 11/45 (128KW) and
used vtserver. This is also useful for a test as you will see if writes
to the drive work (plus the fact that loading anything substantial will
take a while, you'll be seeing how long your '11 will stay up running
*real* code).
