[comp.sys.apple] ADB Y connector

aj0@sage.cc.purdue.edu (Eric Mulholland) (12/13/89)

    After being off the net for two weeks while my computer was down and
getting back on and finding 200 new messages waiting (some of which left
the queue already), I was surprised to see so many.  By reading the news
every day, it sure doesn't look like this much traffic.

    Oh yes, my subject isn't about traffic, but on those ADB Y connectors.
Well, since I posted way back when, here's what I found out (and got).
There are two known places that this Y connector can be had from.  The
first place I was informd of is Redmond Cable.  I called them up and ask
them about about there cable.  They said it was a male plug with two six
inch cords coming out of it.  At the ends, each having a female plug,
thus you plug the keyboard and mouse into them.  Then I asked how much?
They said $30 for it.  I decided to wait for another reply.

    The other place I was informed about is ELPE Enterprises.  The cable
they have has the male plug, a flat cord that goes about 6 inches, splits
to two cords.  One is about another 6 and the other about 10 inches.  Each
ending with a female plug.  I first wondered why the cord was flat and
different lengths.  The cord is flat so that it can run underneath the
computer and not be crushed.  And the reason for being different lengths
turns out from the fact that the ADB port on the back is not in the center,
but off to the left side.  That way when the cord comes out each side from
under the computer, it's at the same place.  The price?  $15 and $1.50
shipping.

    I got my cable from ELPE and everytime I move the keyboard around and
not have the mouse come dragging behind, the more I like it.  I was,
thinking how people are complaining about how a connector on their keyboard
is acting up.  This would be a cheap way to fix it.  Shoot, the dealers
around here are likely to say "new motherboard" even though the problem
is in the keyboard.  Oh yeah, ELPE's address is:

	ELPE Enterprises
	3788 Elco Street
	San Diego, CA. 92111
	(619) 571-0757

    I lost the address for some of the people who asked me forward them the
information I get, but I figure more my be interested in my findings.  A
person mailed me saying that the ADB is serial and not parallel in that only
one bit is transmitted at a time.  That is true, but I was thinking along
the lines of how devices are connected to it.  The keyboard looks serial
ib the way things are hooked up, but electronicly, it's parallel.  If it
weren't, then tell me why this Y cable is working?

Serial and parallel normally refer to transmission of the data bits.
Connectivity is described by terms like star, ring, or (in this case) bus.
