Apart from all the embedded systems providing remote diagnostics and live data.

The win98 embedded systems didn't appear to be intended for live connection. One of my tasks during development was to pull the previous day/night log file from the robots onto a laptop and email it back to the office.

Upgrading embedded win98 to embedded xp was a problem as the hardware was obselete. We were literally hunting through office computers looking for compatible but faster processor chips which we could plug into the dedicated mother-boards.
We did find some.
