I found this amusing "complaint" to Byte in this same issue (https://archive.org/stream/byte-magazine-1981-08/1981_08_BYTE_06-08_Smalltalk#page/n31/mode/1up https://archive.org/stream/byte-magazine-1981-08/1981_08_BYT...): April's Foolers The hasty printing of data concerning our Black-Hole Diode is not only an inva- sion of our corporate security, but is not in the national interest. (See the April 1981 BYTE, page 363.) [https://archive.org/stream/byte-magazine-1981-04/1981_04_BYTE_06-04_Future_Computers#page/n362/mode/1up https://archive.org/stream/byte-magazine-1981-04/1981_04_BYT...] Our device, which is covered by US patents and is classified by the National Security Council as "Top Secret," should not be pandered about in a general-circu- lation magazine for all to see, especially when those not friendly to our nation may learn details of this device. Furthermore, how BYTE learned of the existence of our device is unknown to us, but be advised that stricter security has been imposed to forestall any further lapses. Be also advised that the company BYTE lists as being responsible for creating the Black-Hole Device, Spatial Regression Ltd, will shortly receive summons from our legal department. Any repetition or further disregard for national security regarding this device or its uses in particle-beam research will bring about swift and final action. J.W. Kelty Chief Executive Officer Code-7 Electronics POB 1505 Modesto CA 95353 And Byte's response: Each year, the BYTE staff enjoys slip- ping a few joke items into the April issue for our readers to find; some are subtle, some are outrageous. Response to this year's foolishness was greater than in any year past. In case you missed it, look for "Lost Dutchman's Bug" (photo), page 302 "Black-Hole Diode" (new product), page 363 "Noise-Emitting Diode" (new product), page 364 "Slightly Used Cray-1" (unclassified ad), page 414 So you see, there's no need for "swift and final action" (gulp!) — we were just kidding! By the way, where should we return the sample device that was in- cluded with your letter? . . . CPF
