64×16 are also the standard dimensions for a Forth “block” (record in a record-based file, basically, also buffer in a buffer pool used to read and write said files and screenful in a screen editor for them). Probably unrelated, as there aren’t many reasonable power-of-two screen sizes, but still curious.

Which I suspect means simply that, when the I/O facilities were added, 1024 was the largest sector size among the target platforms, and all others had smaller sizes multiples of which added up to 1024.
