Ah, no. I just misremembered where I read about it.
Mine probably has the bog-standard RX02 boot, but I can see about
dumping it, especially if it's different than yours.
After years of
looking, thanks to a tip from this list,
Did it wander further? My postings were to pdp8lovers and alt.sys.pdp8 Are there any
ROM dumps of the MR-78 anywhere?
Not that I know of. I have a MR78-BD on mine. The print set doesn't list
what that version does. I probably can dump it if its different from yours. OS78 images of the disks that came with my VT78 are

Thanks!
Also WPS78 here

Got that, I think.
And COS for the VT78

Never played with COS. I have one COS DECtape for the -8/e + TD8E. I
think I booted it 25 years ago and didn't know how to make it do
anything and put it back on the shelf.
The closest source I know of is OS78 V4 which was for
the DECmate I

I could use that for my DECmate I anyway.
Enjoy your new toy.
Thanks, and thanks for the pointer to it in the first place.
