PS I was reasoning that Hardware test would run without Mojave starting (or
failing) and, besides, there’s an emergency 10.6 on one of the drives which
will run preMojave hardware. I assume hardware test is firmware (?)
Thanks,

The old graphics card may not boot the Mac if it’s on Mojave and isn’t
compatible (hence having to replace it in the first place)
Can you boot successfully into internet recovery?

Yeah, I have the old graphics card so could replace the new one and run the
test (it's just very fiddly to connect the cables with my eyesight being a bit
old, and I've been trying to avoid it!). Annoyingly it won't do anything at all
on any OS with both left installed.
And I had the same thought after looking at the Mac mini spec- I could get a
thunderbolt 3 enclosure. My main need is not the power (having five disk bays
is nice though!) it's multiple monitors and I was surprised to see a mac mini
can drive three with the right attachments. It can also get really expensive if
you max it out!
But I didn't want to buy anything until the apple chip versions came out...
Thanks Sam. I did think the new ones were locked down, as it were but wanted to
double-check.
cheers,
Jason
