That's probably the same one I have.

I soldered a socket with long enough pins onto the rear-most S-100 slot of 
the Super Expansion Board, then inserted the protruding pins into the S-100 
motherboard, and soldered them again, sandwiching the S-100 motherboard 
against the bottom of the Super Expansion Board. It was ugly, but worked.
This was 20 years ago though. Now, I see no need for more than two S-100 
slots, so I've actually just undone this to clean up my Super Elf, leaving 
my Super Expansion Board with just the original two S-100 sockets. I'm hoping
to be able to just use the N8VEM EPROM (RAM+ROM) S-100 board.

I have the copy I originally purchased on cassette tape, but I believe it 
is like the same as in the Yahoo Groups CosmacElf Files area; I haven't tried 
reading the tape recently, though was going to give it a shot at some 
point.  https://groups.yahoo.com/neo/groups/cosmacelf/files/BASIC/

Looking over the manual though, it looks like although it could run from
ROM, it wants to be at 0x0100, which isn't so convenient.

When I built the Expansion Board, I was a year or two after the Elf, my
soldering skills had improved. I decided to leave the RAM chip sockets 
alone, and will likely pull those chips leaving empty sockets anyway, 
provided I can get the full compliment of RAM working in the S-100 bus.
