Yes. It was actually a Dutch idea (and there are therefore articles about 
it in Elektor).

It was called (with the obvious pun) 'The Chip Shop Takeaway Service' 
:-). 'The Chip Shop' was a programme on home computers that was 
transmitted in the later afternoon of either Saturday or Sunday (I forget 
which).

I've never seen the translator program for the Dragon, but there's no 
reason why there shouldn't have been one, and AFAIK no extra hardware 
would have been needed. I think the only machine that needed extra 
hardware was the TRS-80 Model 1 (and maybe, therefore, the Video Genie), 
since the built-in cassette hardware was pretty much designed round that 
machine's 500 baud scheme. The Model 3 did not need extra hardware, you 
could use the 1500 baud hardware to handle basicode dignals with the 
right software

As luck would have it, My only computer at the time was a Model 1. I
remember getting the translator tape, and the next weekend going up the
Edgware Road in London (back then it was full of shops selling electronic
components), buying the bits and soldering it together.... 

The other problem you may have with the Dragon, and which I had with the 
Mdoel 1 is that Basicode sort-of assumes a 40*24 text display. It's not 
supposed to (you're supposed to call a subroutine loaded as part of the 
compatibilty routines which loads a couple of variables with the screen 
size), but many programs didn't bother, or didn't do the right thing if 
one or both of the dimensions was smaller than expected.
