I think the company that made them, Body Solid, is still around, but the Iron Flex mini-gym seems to have gone out of production around 2003 or so. Or at least that's when the www.iron-flex.com website went away according to web.archive.org . There was also another similar model that used a fixed weight stack rather than removable free-weight plates.
It's really cool they were able to fit a fairly complete home gym in a space 39" by 90", folding up to 39" by 54".
