[GreenKeys] Help with RTTY

[Gerald]

Hi Folks
First time post and have a few questions.
I came into some Teletype equipment and would really like to get it up and 
running.
The problem is There is so much that I just don't know where to start.
I also know very little about the RTTY in general. Some of the equipment 
that I have can be seen at
http://www.projectgm.com/html/teletype.html I also have a BC-348-P that I 
would like to use if I can with this equipment.
I have also purchased a MFJ-1224 RTTY/CW computer interface. I am not sure 
if I can use this and it did not come with software.
Does anyone know what software would work with this or where I might find 
it?
I have also purchased a Heathkit HD-3030 (unbuilt kit) RTTY Terminal 
interface. I am not sure if this is what I need either.
I did plug in the Model 19 that I have and it does run open. I do not think 
that the power supply that is under the bench that it is on works.
Is there a power supply that I can build to run these? I am open to any 
advise that I might get and I would really like to get them up and running.
Thanks
Gerald
