[Coco] 26-3127B <-> 26-3134B Coco 2Bs

Hi Coco 2B Hardware Gurus!

This may be old news to some of you so those of you who don't know, I have
recently (within the last few days) discovered that the memory area of the
26-3134B Coco 2B which I have looks Identical to the memory area of the
26-2127B Coco 2B except for the following differences.  

I have yet to check my 26-3134B motherboard yet, but if I remember
correctly, my memory is implemented with two 4464 chips and has a two 12 pin
female headers, one near each chip.  Whereas MarKO's 26-3127B's memory is
implemented with 8 - 4164s.  Where he has memory, my motherboard is blank
and where I have memory, his motherboard is blank!  Other than that
difference, are these two Coco 2B motherboards identical?  Is the same
motherboard being used for both model numbers of Coco 2Bs?  They both were
made in Korea, so this seems possible.  If that is the case, then Why?
Memory chip supply problems?  Why two catalog numbers?  Inquiring minds want
to know!  Scooby-Doo, Where are you ?
