Updated the perl assembler and made some code changes to the listing. I 
think I have it assembling now. Feel free to grab a copy if you like:

http://www.cs.ubc.ca/~hilpert/e/HP21xx/software/abl.html - original

http://rikers.org/hp2100/asm21-pl.txt - updated assembler

http://rikers.org/hp2100/abl.asm - source
http://rikers.org/hp2100/abl.lst - listing
http://rikers.org/hp2100/abl.abs - tape image

the perl script adds 20 trailing nulls. How may are really needed?

my basic1.abs has 0x80 as the last byte but it's after nulls. I assumed 
that was not needed and removed it.

What tape image manipulation tools do we have?
