Re: Advice on custom input/output for pc

["Graham Howe" <graham@xxxxxxx>]

I downloaded technical info from manufacturer's site and it appears that
the
controller is built in to VFD module just like with the LCD ones. The only
thing I can't work out from the site is the connection to the parallel
port.
I have found this diagram,

which show connection of a HD44780 type LCD so I am hoping it is the same.

Graham
