I know it's like " is it pronounced 'tomato' or 'tomato' " but people get very upset over this sort of thing. Nadcomm lists 33ASR so I think that's probably the final word on that. Putting 'teletype 33 asr' into google.com gets many referances to ASR 33, ASR-33, etc. So does 'teletype asr 33'. --Chuck
