Oh, dear. I guess we need to clean that up. Our first error is letting you conclude that "TSAF would be the right component" without having alerted you to ISFC. We compounded it by describing hardware that no longer exists. To answer your question, the IBM ES/9221 and its predecessor, the IBM 9370, were rack-mounted machines with integrated network and terminal adapters, as well as having internal dasd. TSAF is still a wonderful alternative for connecting second level systems together or to a first level system since it can use virtual CTCs (ISFC cannot). However, TSAF cannot drive an OSA. If you would, please submit a Reader's Comment Form describing your confusion. (That is, send a note about it to mhvrcfs at us.ibm.com.) Alan Altmark z/VM Development IBM Endicott
