Well that was a challange. John gave one of the WD_C2401P LCD modules to me and I played with it till I got it to work.

Here’s the new code:
to startup
 write porta-ddr 0
 write portb-ddr 0
 cc $1C cc $14 cc $28 cc $4f cc $60 cc 1
 dd 32 dd 32 dd 32
 dd 72 dd 101 dd 108 dd 108 dd 111 ;Hello
 dd 32
 dd 87 dd 111 dd 114 dd 108 dd 100  ;World
end

to cc :xx   ;send a command
 clearbit 2 $f89    ;clear RS to write commands
 write portb :xx
 setbit 3 $f89      ;clock the command in
 mwait 2
 clearbit 3 $f89
 wait 1
end

to dd :xx  ;send character data
 setbit 2 $f89     ;set RS to write data
 write portb :xx
 setbit 3 $f89   ;clock the data in
 mwait 2
 clearbit 3 $f89
end
