No, potted modules, that epoxy was very common in the 1960's and 1970's as an encapsulant. Hard, low thermal expansion and resistant to a few of the more common solvents. Does survive moderate heat, and keeps what is inside safe and free from shock.

Hmm I used to have some IBM SLT modules but I can't find them right now. IBM really pioneered many concepts in packaging back in the 1960s and reading some of the old stuff, it could have been written last week. Face-down bonding of die, computerized testing of assembled modules, etc

youtube is filled with IBM videos of the era.

As someone who has worked with IBM (mainframe) equipment for 35 years I couldn't help but notice the familiar device numbering system on those chips. For as long as I've been in the industry IBM has numbered pretty much everything - hardware, software, manuals, you name it -  with 7 digit codes. The code is usually made up of a 4-digit "device type" followed by a 3-digit "model number". Over time the digits became alphanumerics. In addition, any optional extras for a particular devtype/model are usually identified by a 4-digit "feature code".

I have no idea whether that convention was in force when the chips were manufactured, but if so it's remarkable that it has lasted to this day.
