Yes, but if you look at the picture/manual (I found a "Module location for
I/O" chart on pg. 335 of the PDP-7 Maint Manual - alas, not the whole
machine, just the FLIP CHIP part), the PDP-7 is all B-series and R-series
FLIP CHIPs, which are all discrete transistors.

AFAIK, the first ICs (in the modern sense) on FLIP CHIPS were on M-series.
