I know hercules emulates the 2703, I think and allows emulated bisync support, and that is not covered by licence, but NCP is. sorry for the off topic boring drift of this. There are other com controlers, a 3745 and also someone has a hugely priced 2540 reader punch (19,995) (vendor is retrosoft) as well as another vendor with a 3803 (Patrick are you sure yours works?) for Patrick, an his problem with his mainframe pile, are the LIC software sets covered by strict license? I thought you could get replacements and could request whatever you liked, though your box was sold as a "coupling facility", it might be worth asking for a regular LIC set. For those who may encounter hardware by IBM in the wild, there are 8" diskettes which were the firmware for a lot of the older devices, or configuration diskettes. Newer systems which may have either PS2/30's PS2/70's or laptops which control the systems have software you load on said systems to in turn boot the IBM boxes. Some scrappers swipe the PS/2's thinking they are all the same, and you have a devil of a time replacing them, and frequently can't get the LIC to reload them. Jim
