Nice.  The caption is odd; it claims that "... instruction set was compatible with the /30 through /91 models" when the pamphlet itself makes it quite clear that this is not so (no SS instructions).  

It's curious that the emulation feature, which adds software emulation of those instructions, isn't mentioned, and in fact I haven't seen it mentioned anywhere.
