You should be able to find at least some clear (free, not encrypted) signals in your area that those receivers will pick up without a card. It may not be something you'll actually want to watch, but at least you can test your receivers. Some receivers can be programmed without their remotes. If they are a common type a cheap universal remote should drive it.
There are various sites full of satellite info that should tell you what free channels can be received in your area. There's probably actually more channels available to you than there is here (where pretty much all the good stuff is encrypted or on C-band).
The rack probably came out of a hotel and was used to distribute satellite TV to the various rooms. I once found a similar setup here, but it was using MDS receivers which are now totally useless. The modulators and distribution amps were definitely worth having though. The system I found had provisions for some kind of in house guide channel, but unfortunately someone else beat me to whatever was generating this channel.
