After a rant on Google+ Craig Trader pointed out the Sailfish firmware to me.
It seems that a user named Jetty has created an alternative firmware for Thing-O-Matic, Replicator 1 and even the old Cupcake printers that Makerbot seems to have abandoned.
By his account it took 10 month and the prints he shows shure are impressive both in detail and speed.
With my 16-32mm/s his 120mm/s sound just crazy fast!
It also has that pause feature I loved on the RepMan (I started writing it for the ToM firmware but never got to use it there,)
