Well, it could find the transaction details from an online source but I guess that feature hasn't been added.  Looking into bither on android to see if I make any progress there.  Thanks.

That feature exists but you'd have to rely on someone running a DB for you.

Ok.  So I can't do what I want - I have to download the entire blockchain on the online computer.
Yes, you will have to download the entire blockchain in order to create the unsigned transaction. There is no way for Armory to create that transaction without knowing what transactions it can spend and what the output scripts for those are.

Thanks.  That part I get but it seems that installing armory installs bitcoind which automatically starts downloading the blockchain.  I'd like it not to do that on either computer.
You will need to do that on the online computer. The offline computer won't do that since it won't have an internet connection.

Yes. The online wallet creates an unsigned transaction with all of the necessary details for signing the transaction (except the private keys) which you then take to an offline computer and sign it.

...to download the blockchain?

I just want to make a quick transaction, sign it, then broadcast it.  I don't want to download the blockchain to do this.  Is this possible?

Thanks!
