Yes, but not a CRT: cardboard boxes going down a conveyor.

I used to design coding and marking equipment for batch coding goods and boxes of goods as they go down the conveyor. Limited processor (32MHz Z80) and even more limited RAM (32K), but 128 individual dots (35 picolitre per dot)to print in a single vertical slice, then a brief pause, and a second slice, and so on. Most companies get the signal from the photocell, and build a bitmap image to print. But that uses RAM I hadn't got, and takes time on a slow processor. So instead, I got the photocell signal, grabbed the date and time (could be part of the print) and started an timer interrupt. Each time the timer ticked, I generated a new slice and fired it out the jets then set up for the next one.
Basically deferred the processing from a lump at the start to a little bit each dot.

Worked brilliantly on boxes of product, but was just a fraction too slow to cope with high speed lines of individual products - it would reach the point where the processing took longer than the timer interval and the message would stretch across the product.

And I still see units that I designed and coded are working fine even today walking round the supermarket ... I recognise the font I used and it's slight imperfections! Laugh | :laugh:
