Yep, thats the memory adapter cards we have been discussing.  Would
imagine that one could socket the board and then get the chip
numbers from another board and have a coprocessor board.  Been
thinking of trying it myself as I do have a couple of memory
adapters left.  Might be fun to see if it works:-).
 
Later...

Well, I bought these chips from a company in California called BJS
Electronics, mail order.  They were marked 'Korea,';
but I don't recall if I could make out any manufacturers name. I was
very careful about bent pins when installing them, and I tried
installing just one bank (9 chips), substituting various of
these 256K chips, but NO WAY could I make them work.  Either
they were all bad, or there's some incompatibility problem. 
This was a bow 100B.  I exchanged them for 150 ns chips and had
no problem. I can't figure it out.

  The Memory adaptor board is the 8087 board with the 8087,clock and a
few more ic's and resistors missing.

No, the Rainbow is much slower tha I imagine a 386 would be (even with
a '286 TURBOW in my Rainbow), and the fancy 3-D graphics don't
appear. However, under Windows I can produce graphics output
that the RB just can't do otherwise.  Excel works well, as do
the desktop applications (Paint, Write, etc). So far the only
glitch is the "calculator" - not an issue for me.  In terms of
speed, I prefer to do my heavy number cunching in 1-2-3, and
then convert over to an Excel format only when I'm ready to
produce finished graphs.  The only limitation is that some
Windows aplication require 1 MB of RAM - out of reach for the
RB, but there are usually smaller applications that do the same thing.
