Both are 64KB
The Academy EPROM labeled "16KB" is a 32KB EPROM.

However:
Both only use 48KB. On Academy and Polgar, CPU addresses 0000-3FFF are for I/O and RAM. (and no ROM banking tricks)

The file data for T+T is already very similar to Polgar 1.10, and I expect more similarity with the yet-undumped Polgar 1.00.

Milano: Yes, also 64KB ROM. 0000-1FFF for I/O and RAM, so total program+book size = 56KB.
