Can anyone help ID the manufacturer of this IC? I couldn't resist popping the lid on one.

Nice board! CMI - Computer Microtechnology Inc.
Computer Microtechnology, Inc. was an early MOS Memory manufacturer. One of the early casualties of Intel's aggressive market dominance.

Yes, they are on the MAP board of the Multidata Model A minicomputer
Here's a nice mixture of Fairchild DTL & TTL from one of the 4k x 18 memory modules.

After a closer look at the MAP board, there is in fact one lowly 3101, whose ID I can't make out.
