Just use any RF modulator such as found in, say, a bbc micro, to create the 
RF the teletext adapter needs..

I did at one point [*] try to use a beeb to generate teletext signals; I 
shifted the screen start up into the right region, so could display 
teletext signals across the right scan lines.  I never got further than 
getting the TV to acknowledge that something was there, as the only 
teletext tv I had access to at the time was at the other end of the flat, 
and it was a pain running backwards and forwards..

My TiVo generates teletext pages, albeit only no. 888 for the subtitles.  I 
imagine that there is more generic software out there that could be used 
for demonstrations, etc.   I would also expect some of the actual 
commercial hardware currently in use by the many broadcasters to filter 
it's way down to hobbiests once it becomes redundant...
