Not the 0.5 Internet. That would have been a pre OSI model IMP version (See 1976's BBN Report 1822), which most agree culminated in Internet 1.0 and included the use of TIPs ... The Morris Worm ran on the later TCP/IP Internet which went "live" on January 1, 1983. This can be considered Internet 2.0, and was fairly mature by 1988.
