Humm...
Have you seen its price??? (around 12$US)
I think it is kinda cheap for an extra Ram Cart...
Then again I know that there are backup carts up to 64Mbit, made by 3rd party companies like EMS...
Now that I think again... maybe your right fivefeet8, as 32Megabit equals to 4MByte, and 8Megabit equal to 1MByte...
That gives us a 4/1 MByte Cartdrigde... but that too cheap in my opinion... but one can never know...
"... What gives it away as the ram cart is the 32/8 mbit part and it says Dram on it... " fivefeet8
Maybe that's what makes it a Ram Cart as 32/8 <-> 4/1 , and has I said maybe even with support for 4MB and 1MB....
