This is the 8-K Basic.

most important:
  the program doesn't start at SA=0200.
  it starts at 1000!

I assembled it with PAL-8 with option MACHINE=0 and it runs on my LAB-8/E.
I didn't exactly find out, was 
  "THIS CODE OVERLAYS THE BINARY LOADER IN FIELD
   ONE TO MAKE LAB-8/E BASIC SELF STARTING."
exactly means, because under OS/8 there is no binary loader in field one.
But the effect is, that after loading and running BASIC8 under OS/8 the
system becomes inoperable: it cannot be restarted, I have to boot.

Perhaps there is an exit to OS/8-command, but I didn't find it. I also 
didn't try to assemble it with MACHINE=1.

What also didn't work: loading BASIC8.BN with the old  LBAA-PM binary
loader. Eventually this loader has no provision to load in different 
memory fields. I'm looking for a newer loader.

For completeness, I copied the docu for this BASIC from bitsavers to this
directory too.
