Might you have any updates on your Nixdorf 620 / Entrex 480 system?  I am
quite interested, and it's been a while since I've seen any email with
these keywords here, from you or anyone.

Someday, it is my hope that I might take a tour of your system in Belgium,
on my next trip to the region, if you would be open to this.  I am quite
fascinated by this rare dinosaur of a system.

I have begun to archive your work, and everything else I've ever found
about the Entrex 480 systems here:


Like your system restoration, it is a work in progress...

Best always,
