Two aspects of IBM’s forthcoming OS/2 operating system for the Personal System/2 are disconcerting: the first is the fact that it costs $325 – with the SQL and SNA extensions no doubt being separately charged if IBM ever succeeds in finishing them; the second is that the thing is called OS/2 and succeeds what people have come to call DOS – just as DOS/VS was succeeded by OS/VS 1 and then OS/VS 2 which evolved into you know what, at this rate, by 1990, IBM’s micro users will find they’re expected to pay $10,000 for a Personal MVS/XA.
