There definitely was:
It contains the MCA bus enumerator, the ADF files, and a couple of BEF
drivers for devices that don't have ISA/EISA/PCI variants.
My recollection is that Sun ordered about 100 MCA media kits and gave them
to their Tech Support people to have on hand for any customer requests.
I heard that in the following 12 months they had exactly two requests for
the MCA media kits. So in theory, if you've got a support contract for
2.6, you should still be able to request it from Sun.
There's a long story behind why it's a separate media kit. Sun's DCA
developers ran out of room on the DCA floppy when they tried to put
everything for all busses all on one floppy. They thought they could get
away with segregating all the MCA stuff on a separate MCA-only floppy.
I think I was the one that pointed out to Sun that, unfortunately, the
one Sun customer with a (major) support contract, that actually had MCA-bus
systems was using IBM servers that also had EISA and PCI slots (and that
MCA-only systems were probably no longer being built). Therefore a MCA-only
floppy wasn't going to work for the only customer that mattered. Because
the standard DCA floppy was still nearly out of space, even leaving out the
MCA stuff (and perhaps so they didn't*off their one paying customer
that required MCA+PCI+EISA support), Sun ended up compressing various
files on the floppy so that it could all fit. But since MCA was being
phased-out anyway, Sun decided to not put any MCA stuff on the standard
DCA floppy even though initially most of it fit once they switched to
using compressed files.
