Phil, BOS/360 (predecessor to DOS), TOS/360, TSS/360, RTOS/360, MTS, DPPX/370, and UTS (Amdahl UNIX) should be added to your list.

Today's random wondering: how many operating systems can folks remember having run on S/360 and descendants? I can think of: OS/360 (including MFT, MVT, MVS, up thru z/OS, including MSP and VOS3) VM (CP/40 up thru z/VM) DOS (or did it start as TOS? Not my turf! up thru z/VSE) ACP (up thru z/TPF) TSS MUMPS MUSIC PICK AIX Linux, of course Solaris, almost ORVYL? WYLBUR? I think ORVYL was the OS and WYLBUR was the user environment - sort of the CP-CMS or z/OS-TSO relationship, but canna remember for sure; someone here will know VICOM What others? No credit for things like DDR or ICKDSF, which, while IPLable, aren't really "OSes" in any kind of real sense! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
