Tandy 600 (was:Tandy MC5000)

Just how many of the 600's were made/possibly are still in working order? Just how rare are they, and how much would one be worth? I had people trying to sell me non-working ones for $50 and over (I didn't buy them because I have a working one). Also on the topic of the 600, Does anyone have a modem cable and a printer cable for one (or a BASIC chip)? One last question... Is there any way to run non-ROM programs on the 600?
