This article about the discovery, debugging, and patch of a timing glitch on the Mars Pathfinder caught my fancy.
Its system architecture reminded me of the three-bus architecture of Masscomp “real time unix(TM)” machines, which I came to know intimately “back in the day” (84-86) as a side effect of writing the damn ‘theory of operations’ manuals for it. And anyway, as any of y’all as have read the first page of my Acts of the Apostles knows, I think the discovery-and-debugging of timing glitches is inherently interesting.
Outer space and spacecraft and actual hardware are Gary’s beat around Wetmachine, so here’s my respects, gov’nuh.
By the way, Google came up with an article on the Masscomp architecture but you need an ACM membership to read it so I’m not bothering with it, as my account has expired. If anybody has a Masscomp architecture diagram lying about, kindly post a link.
