Interesting.
I would note that the IRS had no problem getting new computers and software in 1999. It's clear where their priorities lie.
As someone who worked on both the IRS Y2K effort, and the Maryland State Treasurer's Office effort, I can tell you that no one in the banking industry got new computers. Banking transactions were ALWAYS transmitted using only the Julian day as the transaction date. There were two digit years in the headers, but within transactions actual dates were generated by windowing the Julian day in the transaction against the current Julian day in the computer. So any reports that the Banking industry was going to have trouble on Y2K were made by folks who didn't know anything about the system.
