Jim,

If you take the 18 64K chips from Board 2 and place them in Banks 2
and 3 of Board 1 (with the 9 256K chips already in Bank 1), your DIP
switch settings should be:

Switch  1   2   3   4

On    x           x
Off        x   x

If you do the opposite -- place the 9 256K chips in Bank 3 of Board 1
-- your settings should be:

Switch  1   2   3   4

On            x   x
Off    x   x

Either way, you have 384K on the expansion board + 128K on the
motherboard = 512K total.  BTW, if you're interested, now's not a bad
time to replace those 64K chips with 256K chips.  As of a couple of
months ago, you could buy 120ns 256K chips at about $2.60 per chip.

Tell your friend to save his time... it won't work.  The Rainbow communication
hardware is completely different from that on an IBM PC, and software written
for IBM PC comm ports just flat-out won't work (unless the author took care
to support the Rainbow as well, and those are few and far between).

Thanks for the advice.  I know my friend would love to use Telix, but I
guess what he really wants is to be able to use a transfer protocol other
than Kermit which is what he is using now.  I will pass your suggestions
on to him.

Thanks again,

Dave Spaulding.
