I bought HP 28S shortly after the release of the heavily crippled (and apparently already discontinued) "C" model.
Perhaps "not sufficiently RAM-equipped" describes it more accurately. After playing with it for a little while, everyone agreed that 2K of RAM would not be enough for this beast, especially with an unlimited-height stack and RPL. However, I believe that is all they could cram into it at the time and keep the costs reasonable. If I recall correctly, when Bill Wickes demonstrated it for the first time to the Washington D.C. PPC chapter at the University of Maryland in February of 1987, it turns out that his own machine had been wired special with the original 2K plus additional 16K RAM from an HP71B memory module soldered in. He admitted that 2K was not enough, but that it was pretty much a proof-of-concept for starting the RPL generation. In the British journal Datafile, the V7N2 (March, 1988) issue which introduced the HP28S had the words "Enough Memory At Last" in very large letters on the cover under the photo of the machine.
