I don't recall the paging but it makes sense.  I made the huge 
mistake of tossing the source and executables after UCSD yanked the 
licenses.

I did a lot of customization of the interpreter to add IO devices.  
It was a very interesting system.  It was even more interesting when 
Western Digital built the p-system in silicon.  I would have like to 
have one of those boxes but I haven't run across them on e-bay.

Yes, they added UNITS but I don't want that feature.  Simple 
programs, one pass compile and go will be fine.  If I need more I 
have Turbo Pascal under PC-DOS 7.  Or one of the offerings under 
Linux.  Actually, Turbo Pascal was my plan for step 2.

I had actually thought to do Lee Chen Wang's Tiny Basic but I don't 
think Basic promotes good program structure and it would be a waste 
of an ARM processor.  But it sure worked well on an 8080 and 8085.

Who is making the board and when might it be available?  It's not 
like this project is urgent.  My grandson is only in 2d grade.
