Assembly is fun, and useful.

I've learned the assembly language of quite a lot of machines.  The strangest, by far, is of the Electrologica X1 machine.  It's only barely an assembler, really -- more than machine language but not by much.  Then again, the assembler is only a bit over 100 instructions long (it's part of the ROM BIOS of the machine).  You can see the full BIOS listing in the back of E.W. Dijkstra's Ph.D. thesis, where he worked out how to deal with a machine that uses interrupts (that was back in 1958; the X1 was the first commercial computer with interrupts).

A very small example is here: http://helloworldcollection.de/#Assembler%C2%A0(X1)
