Where can I play older maps?

[ebevan91]

I first played this back during .7 something but I only played it for a few minutes because I didn't like the gameplay back then but now that I love PR and play it almost more than anything, I'd like to know where and/or how I can play some of the older maps, is it possible to?

Well there is a few mappacks for PRSP, however I don't think the old maps are compatible with the current release.

AFAIK ages and ages ago in an older release I think there was coop or SP for one of them, vaguely remember playing with bots on Mao Valley...I could just be tripping though.
