Yup, at OCF we had 3033 and 3031 systems.? The 3033 was MP and the 3031 was AP.

OK, so I'm curious. MPs were available at the same time as APs, IIRC.
My recollection (fuzzy as it may be) is that MPs were available before APs. (The hardware, I mean, not the OS support.) Of course the 360/65 had an MP option, but it was architecturally a bit different from the S/370 MPs.
The way I remember it is that when the 3033 came out it had MP and AP options (but not both - there was speculation as to whether they might later do an MP/AP version with a total of four processors, but that didn't happen until the 308x generation).
Was there ever a 168AP? There was certainly an MP, but It seems to me that AP was "back ported" to the158, probably because the implementation on the 158 was much easier and less hardwired than the 168.
But I digress...
