OS SE can only run 1 machine, but Flex and Flex + can run multipul machines. Some older versions of the base level operating system, back when it was ACPS not OS, were able to run multipul heads which ran as a conventional machine does, all in time with each other, starting stoping etc. This would have been true for Aaron's machines with serial numbers in the 200's =========================================================== The AmayaUsers Mailing List Website: http://www.amayausers.com Discussion Board: http://www.amayausers.com/boards Subscribe/Unsubscribe: http://www.amayausers.com/list ===========================================================
