The presence of the words 'NAND GATES' imply that this was part of some
educational kit for logic training, rather than a part of a system.

RCA made boards of this color and size, but not an exact match. Same
number of pins, similar blue. Not claiming it's RCA, but it's the
closest thing I have.
Here is one from a 1974ish COSMAC Microkit:

The photos are of a board I recently obtained for my collection. I've not,
to date, been able to discover who the manufacturers were. It almost
certainly US, The chips are week 27 of 1970, NAND gates.
Can anyone help?
Many thanks,
peter
