IC as in digital logic were in production in the early
60s
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.

The B198, B199, and B250 modules of the KA10 use ICs. First customer
shipments are claimed to have been in late 1967.
From something I posted back in 2002, slightly updated:
B198 Protection Comparator (used in KT10, KT10A "memory protection and
relocation" options)
panel 2MN slot 44, panel 2PR slot 5
appears to be an 8-bit magnitude comparator
prints drawn 6-18-68, checked 6/21/68, eng. approval 7/2/68
5 74H00N
2 74H40N
4 74H50N
1 74H53N
2 74H55N
B199 FM Address Decoder (used in KM10 "fast registers" option)
panel 2KL slot 9
acts as a 4-to-16 decoder (similar to 74154), but
requires both true and complement inputs
prints drawn 3-2-67, checked 4/?/67, eng. approval 7/6/67
8 TI SN7440N or Fairchild 9009 (U6A900959X)
B250 FM Module (used in KM10 "fast registers" option), 8 words by 6 bits
panel 2KL slots 10-13, 15-18, 20-23
prints drawn 3-2-67, checked 6/30/67, eng. approval 7/6/67
6 Fairchild 9030 (U6A903059X) 4 word by 2 bit RAM chip, 45ns
write, 25ns read, 350mW
13 TI SN7440N or Fairchild 9009 (U6A900959X)
