ASR33 questions

I just received one of William's ASR33s and it appears to be in good working order. I am not at all familiar with these machines so I have a few questions about their operation and interfacing. First off, when I power on this unit the "main" motor doesn't run. It turns when moved manually, but it won't move by itself. Depending on the motor position at power-up (I think) I sometimes hear what sounds like a warning buzzer. Is there something I'm doing wrong? How would I run this machine in "local" mode? Once I figure out that this machine is working (I assume the problems are mine and not the machines) I'd like to hook it up to my Altair (which is now running great thanks to Dwight!). How would I go about doing this? I'm guessing I'll need some sort of box to interface between the TTY and RS232, but I haven't yet found any information on that. Can anyone point me to an article, website or some other source of information on this? If I manage to get that all done, is there anyone on this list who has software on paper tape that I could get copies of? I'd be most interested in a BASIC variant and any BASIC programs that could run on it, but anything else would be great. What am I missing? Is there anything else I should know? Thanks! Erik S.
