64Kb was plenty.
Heh, I remember that one.
I remember having to do updates on Cisco routers in the very early 1990s. Cisco would ship me ROM chips to install in our routers, a chore to shut them down, open the boxes and swap the chips. I was happy when they went to software downloads for system updates. Until I had to sit around a long time waiting on the data over our shared T-1 lines (1.544mbps, 24 times faster than standard 64kbps lines), shared with hundreds of users. It took forever... Things improved quickly over the next few years as we added bandwidth. Funny how we thought 1.544mbps was fast back then.
