The last keyboard I had that did this was on my Exidy Sorcerer
back in the middle 1970s. On that machine you could write your
own keyboard driver to `strobe' the key status, and detect _every_
press and release of _every_ key.
Very soon, however, this gave way to keyboards that had enough
logic in them to only send pre-decoded keypress information (i.e.
it would send you `A' rather than requiring you detect a shift
key depression and a 'a' key depression followed by a release of
each key), and since that time I don't know of many keyboard
handlers (except those designed for piano keyboards) that send
key-release information.
