Thanks for the offer! It seems there's some left in Germany as well,
they might be easier to get to France; and you might need the HW to keep
up the great work on NetBSD/sparc :-)

At some point there were some Rasterflex HR on ebay.de, but I haven't
seen one in a while...

Nice. So you can do a SBus-PCI bridge... I wonder if it would be possible
to make a SBus-PCIe bridge in a FPGA :-) Any reference on the bridge
you could share ?

That's what I'm looking for.

Shipping from the US to France is usually too expensive to be worthwhile :-(
I still can give it a go just in case.

Cordially,
