I sat down today to start writing up the diagnostic program for the set of
boards that I will be sending Chris.  My first shock was when I tried to
bring up QBasic to see whether my program will run under the standard QB
that comes with Windows.  Windows did not recognize QB or any of the
possible variations.  I finally found it in the "Old Dos" section of the
Windows 98 CD.  Sigh!  Old Bill has progressed so far from his roots that
he no longer loads QB.  

Well, it will not run.  But close.  The only thing I use from QBX that is
not in QB is an ARRAY in a TYPE statement.  You can just comment these out
and most things will work.  This is used to read from the Memory card to
the hard disk.  Most of you will be able to patch around this.  Some of you
may have noticed that QBX sometimes accidentally shows up on the data
disks.  I will compile a legal version when I send out the cards for Chris.
 He may want to dig up a copy of QBX 7.1 for convenience.  But most things
will run OK.  He is going to rewrite everything anyway.  Still QB is very
convenient for quick tests.  

Just writing this for diversion.  I am tired of writing hit F6 then F1 and
this thing will be tested.  But it is necessary.  I know neither Chris or
anyone else will look at what I am writing until something does not work
and they want to test it.  I am trying to make a nice list so that you can
just go, for example, to "Motor" and see how to make the various motors
move.
