On: My Raspberry Pi Thinks It's a Mainframe

Long ago I found an IBM 360 emulator written in 2 pages of APL and published in some technical magazine. Anyone recall this and have a copy? (I've found websites with copies of similar articles, but lacked the straight-up APL code.)

You're not thinking of Falkoff/Iverson/Sussenguth's A Formal Description of SYSTEM/360, are you? http://www.cs.trinity.edu/~jhowland/class.files.cs2321.html/...

Close, but not quite. As I recall (some 20 years ago) it had two pages of actual APL code (not notation, real runnable code).
