Just what is photo 8? 
 It appears to be an RCA COSMAC Microtutor, which by the looks of things
 is broadly similar to the Popular Electronics "COSMAC Elf"... 
Yes... it's the RCA-badged version.  One of the cards for it that I've
seen pictures of is a 256 byte memory card (dual 1822/5101).  The slots
are marked "E", "P", and "M" - I'm guessing that stands
for Expansion,
Processor, and Memory, since there is no CPU nor RAM on that board.
At least it uses widely-available 22/44-pin 0.154" cards (the same
style the VIC-20 uses)... so if one had just the COSMAC Microtutor
board, it wouldn't be hard to wire up a CPU card and a RAM card.
I have lots of 1802 gear, but I've only seen that one in pictures.
