Re: HP 28s keyboard test and thousands separator. Message #4 Posted by Chris Randle (Lincoln, UK) on 3 Nov 2001, 5:54 p.m., in response to message #3 by Julián Miranda (Spain)
I looked in the manuals again - more carefully this time! The 28S owner's manual _does_ mention the ON+DOWNARROW, on p.291, but says it's a factory test, which "requires keyboard input". Miles away on p.219, it talks about the ON+NEXT keyboard test running top-left to bottom-right.
This ON+NEXT test description is missing from the 28C manual, but in the 28C reference manual the ON+DOWNARROW is described in more detail, giving the key press order as top-left to bottom-right again.
Obviously something changed from the C to the S. I'd say that as long as your 28S passes the ON+NEXT keyboard test, it's fine. At worst it's behaving exactly the same as mine (apart from the keybounce problems!)
