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.
