It's a custom made font I think. There's a fantastic recreation of it lurking around online, made by Mark McMillan, who used to run the APFS website. It's in a Zip File which is located here
The Central 'font' was being used by ATV in the 1970s on internal paperwork such as the memos, although I can't recall its proper title I did have it written down somewhere. But I don't think ATV went to the expense of having it made just for internal documents.

The closest commercial font is ErbarNeo Mini, which was also used in Central's other presentation such as slides and menus.
