from the very ashes of the IBM plant, the same people, with the same tooling, (allegedly) have formed a company called Unicomp, which produces Model M clones.

i I HAVE WORKED at the Greenock center, and the plant is now a set of unroofed, partly demolished buildings sinking in the swamp, so i strongly doubt that they operating out of there.
(it could possibly be the lexington plant, but, if i admit that, i don't get to make any funny remarks. so i will ignore that possibility)
Anyway, it's not a IBM model M, it's an IBM CLONE. Clone. clone clone clone.
It's a very good clone, made by many people who made the original, but hey, it's still a clone.
