I have used Noritake VFDs. I drive them just like LCD displays.
The ones I use have a 14 pin interface.

You may have to adjust the timing, however. Start long and
shorten the time up until it doesn't work - then lenghthen the times
by 30% or so.

I would start with.

DEFINE LCD_COMMANDUS 3500 ; This is a WORD variable
DEFINE LCD_DATAUS 200 ; This is a byte variable

If they work the same as what I have used, you can adjust the brightness
by writing a number into location 0x20 (LCDOUT $FE,$20,brightnessvalue)
where "brightnessvalue" is 0 for brightest and 3 for dimmest.
