1252.0. "What's Different Between D3 and D4?" by TELCOM::ROSENBERG (Dick Rosenberg VRO5-2/C7) Wed Jul 06 1988 09:37

    Can anyone tell me the difference between the Sony D3 and the D4,
    which I have just begun to see at stores?

1252.1about the sameSTAR::BIGELOWBruce Bigelow, DECnet-VAXWed Jul 06 1988 14:3112
    From what I can tell, the D-4 is a value-engineered D-3.  It seems
    to have the same form factor, the same features, and roughly the
    same price as the D-3.  But I think the battery pack is improved,
    if I remember correctly.
    
    Just as an aside, I saw a D-88 a few days ago.  This is a new offspring
    from Sony that plays only 3-inch CDs.  I saw it at Lechmere in
    Manchester.  It didn't have a price on it, and there was no one
    around for me to ask.  Since I really didn't want one, I didn't
    go looking for anyone to ask.

1252.3D-88 = 3-inch onlySTAR::BIGELOWBruce Bigelow, DECnet-VAXThu Jul 07 1988 08:4812
    No, Andy - My D-15 plays full size CDs and also 3-inch ones without
    a special adapter, but the D-88 is something else.  It's about 3-1/4
    inches square and about 1-1/4 inches thick.  I don't remember if
    it had a detatchable battery pack underneath or not.  I looks like
    Sony has finally come out with the player we've been hearing about
    that plays ONLY 3-inch CDs.  I really wish it had had a price on
    it, just for laughs.  How cheap would it have to be to be worth
    buying if it only plays the little stuff, I wonder?

    50� would be overpriced. what a useless concept.
1252.5For what it's worth...GIANTS::KEANEBrian KeaneThu Jul 07 1988 12:095
    The most recent Stereo Review stated that the D-88 *would* play
    both size discs.  Hard to imagine how, given the size of the thing.
    It's list price was about that of the D-15 +/- $20, as I recall.

1252.7OK - that makes more senseSTAR::BIGELOWBruce Bigelow, DECnet-VAXThu Jul 07 1988 15:5212
    re: .5, .6
    
    AH!  That explains how they could sell it!  Pocket sized, I guess,
    but not very usefule.  You sure can't play it in your pocket, and
    it would seem like using it in a car would be risky at best.  Portable
    as in useful in a hotel room, I guess...
    
    The way Lechmere has things fastened down with those metal bars,
    I couldn't get it open, so there was no way to tell.

    To get back on the subject...
    
    Re .1
    	What's the improvement to the battery pack?
    	Is the pack the same size so that it can be used in a D-3?
    
    Rien.
    
1252.9ah, the mini-CD!BOSTON::SOHNMay the Cube be with you!Fri Jul 15 1988 13:0031
	Back to the D-88 for a minute...

	a lever on the underside moves the center spindle between the 3 and 5"
	settings. the "hat" on the top half is moved by hand between the two
	settings. the outer rim has a metal bar, which pivots on the opposite
	corners of the D-88, so that in one position, it closes off the two
	sides, for 3" playing, and in the other position, it allows the 5"
	to portrude from *two* sides.

	Diagram:
