Anyone else have one of these beauties?

Had one I bought in the early 80's (I vividly recall we geeked out until very late in the evening at a PPC meeting the day I got it), and have used it off and on (mostly off) over the years. I just traded it after last year's HHC conference, towards an HP-25C, my first HP programmable. It was definitely old-school, compared to today's technologies, but I just loved the dip-switches to select ROMs, etc.
