software via radio

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. -tony
