Re: HP 30b finally arrived Message #10 Posted by Mike Morrow on 22 Aug 2010, 6:31 p.m., in response to message #1 by Hubert Weikert
I bought one for $50 yesterday at Office Depot in Huntsville, Alabama. They had several on the rack where the calculators are displayed, but I don't think they've been there very long.
Mine is software version "4 5 2010" and physical serial number 4CY02404593. (I guess this must be some sort of new HP serial numbering system.)
Interesting machine. So far, to me the most significant problems are:
(1) very little program memory,
(2) the lack of a real-time clock/calendar, and
(3) the very minimal and barely usable manual.
The HP 20b/HP 30b User Guide that TW referenced does not explain how to initiate the self tests or the significance of each.
