There are a couple of points.
First and foremost is portability. Using as many architectures as
possible as test platforms "keeps us honest" and can be a highly
valuable tool for early discovery of portability issues or "iffy" code
constructs. The VAX in particular is an "extreme example" of many
aspects of processor architecture, and as such, is an excellent tool for
that sort of thing.
Next, some people actually want to *run* it on a VAX. Maybe for hobby
reasons, maybe for "approved platform" reasons, whatever...We don't know
(and don't care) why.
On the "in a simulator" matter: It's important to keep in mind that
there are more VAXen out there than just simulated ones. I'm offering
up a simulated one here because I can spin it up in a dedicated VM on a
VMware host that's already running and I already have power budget for.I could just as easily run it on real
hardware...thereare, at last
count, close to forty real-iron VAXen here, but only a few of those are
running 24/7. I'd happily bring up another one to do Postgres builds
and testing, if someone will send me the bucks to pay for the additional
power and cooling. (that is a real offer)
