Contrary to popular belief :) it seems that Mitsumi can be quick when
responding to *potential* customer requests for information.  45 minutes
from first phone call, to answering machine, to personal response, to
fax-in-hand is not too shabby.

Anyways, here are the contents of a 6 page fax that desribes the
CRMC-LU005S and CRS-UF series Mitsumi CD-ROM drives...

---------------------------------------------------------------------------
The CRMC-LU002S has identical specifications to the LU005S except:

Buffer size: 2352 Bytes
Access time: 1/3 stroke = 650 msec, full stroke = 1.2 seconds

The features of the LU002S are the same as the LU005S except:

The interface is 8 bits
It does not say that it supports photo cd
It does not have a large internal ram buffer

The CRS-UF series seems to be an external version of the CRMC-LU002S 
(it has the same specs).  The external drive is 82 mm heigh, 162 mm wide,
and 298 mm long, and the front loader extends 133 mm.  It has the same
features as the LU002S.
------------------------------------------------------------------------------
The fax does not mention the CRMC-FR or the CRS-XP series drives,
(they are probably discontinued) but Computer Shopper does.

In their Feb/93 edition, CS does a review of thousands of CD-ROM drives,
half of which are probably discontinued or are only available in
Upper Volta.  Anyways, the CRMC-FR is listed as internal full height (!!)

Although the model number is not mentioned, it seems that USA FLEX
is selling the LU005S for $199.  I would guess that the rock-bottom
price is around $175.  I've heard that the LU005S is on national
back-order; is this true?

Anyways, enjoy the info...
