Request. HP calculators (desktop/handheld) production timeline

[Accutron]

I originally attempted to make a complete chart, but I couldn't find the dates for certain later models. I also had to fit it on a webpage, so I lopped it off after 2003 when HP discontinued all of the remaining Saturn machines.

I made the chart in Excel 2007, took a screenshot of it and turned it into a floating GIF in Photoshop.
