I won an auction some time ago on ebay for a hp 48s calculator which came in the box + case + 48sx quick reference guide + 48sx owners manual volume 1. Everything was made in Singapore.
Since this is my first RPL calc, I was looking for the programming section in the manual, which I noticed is to be found in volume 2 of the owners manual, which did not come with the calculator. I then checked a few other 48s auctions on ebay and I see that there exists a specific 48s owners manual.
So what I am wondering is did HP ever supply the vol 1 48sx manual + 48sx quick ref guide with 48s calculators? There is only enough room in the box for one manual, so the seller couldn't have forgotten to enclose volume 2. Anyway, I asked the seller but I didn't get an answer. Possibly the factory just stuffed the 48sx documentation by mistake in a 48s box, but I am just curious if anyone has experienced this.
