You're using the wrong command.

Section 2.2.7 of the "HP 2100 Simulator User's Guide" says:

   The LOAD command is used to install a bootstrap loader into the last
   64 words of available memory within the 32K logical address space. 

The release notes (hp2100_release.txt) for Release 27 that accompany the 
simulator source code say:

   The LOAD command can no longer be used to read general absolute binary
   paper tape images into memory.  The ATTACH PTR and BOOT PTR commands
   must now be used to read paper tapes. 

Try:

  ATTACH PTR basic1.abs
  BOOT PTR
  RUN 100

...and it should work.

                                      -- Dave
