Roy,

GREAT JOB!!! I wanted an interface so I purchased one from overseas. It
is not the RGB2 plus. I'm going to try it out, it should be here
shortly. Way to step up and make this happen.

As far as the volatile memory of the chip set. This is kind of the
chicken and the egg as I see it. If you need to program the chips
before the adapter works then how do you see what you are typing? Type
blind? If programming is required then the chip set should have some
method of interfacing to a non volatile memory source at power up.

Did I miss something???

Regards,

Mark
