17.03.1994/amn The diskette that contained these files had the following label: ----- MARK IV I/O Board Gerber files = MIT.ZIP Drill = DOCMIT.DRL Code Hole Diameter T01 .038 inch T02 .070 " T03 .125 " ----- The archive MIT.ZIP was 'unzip'ped and it resulted in MIT.* files and MIT.ZIP was then removed. The file 'feb94.txt' is only halfway relevant: it contains the description of Ralph Spencer's visit to Haystack in February 1994 when he was given the original diskette.
