The format is much older than that, and although it's possible that there
may have been a 1983 edition of that document, it seems more likely that
the author of the software in question chose 83 because that was the format
number that Data I/O assigned for use with their device programmers. Data
I/O refers to it as "Intel Intellec 8/MDS". Here's a list of Data I/O
formats recognized by the UniSite/2900/3900 family programmers:
