 I have the Motorola docs I got from you, as well my  NMI board came with
 a MC68HC11 Data book (doc # MC68HC11A8/D) and an HC11 programming
 reference guide ( doc # MC68HC11A8RG/AD ).   I have also borowed some
 notes from a fellow that took the 68HC11 assembly language programming
 course that is offered by the Instrumentation and Process Control Group
 at BCIT.

 My Newmicros board NMIX-022 is a Rev 2.1 board that supports onboard
 battery backup for the CMOS ram.

 The verison of Forth is  MAX Forth 3.3.

 I was a little disapointed on my first trial inspection of the Forth
 system....   After reseting the terminal input buffer and dictionary
 pointer to use external ram I decided to try some defintions.

 For some reason while browsing the manual I noticed it included both
 CREATE   and <BUILDS .   I was curious as to why so tried to redefine
 constant like so:

 : CON  CREATE , DOES> @ ;   1111  CONSTANT  JUNK

 Guess what....  It doesn't work!

 Closer inspection of the word descriptions indicates that <BUILDS should
 be used with DOES>   and in the description of CREATE there is no
 mention of DOES>  .

 The above definition  does work if the CREATE is replaced by <BUILDS

 So much for MAX Forth being a super set of the Forth 83 standard...
 You cannot   CREATE .... DOES>  as you can in Forth 83.
