Good job. I caused the purchase of a couple of 720s (I believe they were, plus a few X terminals mooching off the workhorses, all with megapixel color displays). They served well past the demise of then-rival Sun machines. I think one of them was still in use with legacy software a few years ago.

Fun stuff: there was one year that HP-UX got so aggressive about using free RAM for file cache that, when you tried running another program, things would slow to a crawl because it was paging virtual memory to disk ...

This is my favorite part about HN: You have a random story about older tech, and someone who either knew someone involved or was involved themselves is right there to comment on it!
