Ok, first off these are
round pods. The arcade has 4-6 of them (I can't see into a storage area properly because of a fence, but there are some (4?) pods out the front that I can see).
The condition is hard to tell as the corner they are in is quite dim.
They shouldn't cost
too much, as they are trying to unload them
This is part of an email they've sent me:
"The issues with machines are varied but basically the reasons for us to not continue with them are as follows.
a) The licence to use the current Virtual World systems software is too excessive to consider this option
b) The technical requirements to maintain the current system is not in our technicians ability (They're not familiar with apple mac systems)
c) The size of the machines takes up too much room for the revenue that it earns...compared to other machines we could use there.
d) We are struggling to find the parts that we need to keep them operational for the "day in day out" use they receive."
"They as yet have not been completely sold, but we have two other people wanting to make purchases also."

I am going to get more information when I go see them, They are fairly far away and going there is not something you would do spontaneously.
This seems like too much for me

I have very limited electronics skill, I fear all I'll end up with is "a lot of dead instruments in a really cool desk". I'll email virtual world and ask about that software you mentioned.
