I see that this archive contains code for pricing out 11/40 and 11/45
systems, plus options.  This reminds me that I've found several references
to the 11/45 that Research purchased (late 1972/early 1973?) but no
specific details about its configuration.  I presume that it had an RK05 of
some sort but I'm curious about other peripherals and the amount of memory.
