This review is in two parts:  (1) the MDS-PC2 deck and (2) the PC Interface.

Physically, the front panel of the MDS-PC2 is slightly larger than a
half-height 5.25 floppy drive.  Along the left side is (from top to bottom)
the Power button (standby/operate), the IR sensor for the remote, a
mini-phone jack for headphones and the Input selector (analog/optical
1/optical2).  Buttons on the right side are (top to bottom) are Eject,
Play/Pause, Back, Forward, Stop and Record.  The front panel Back and
Forward buttons operate like those on a portable.  That is, pressing quickly
causes it to skip to the next/previous track (the |<< and >>| functions),
while holding the button down gives foward and rewind (the << and >>
funtions).  However, the buttons on the supplied remote are like a normal
home deck.  That is, there are four separate buttons: |<<  >>|  <<  >>.
Also on the front panel is a 1-line flourecent display, similar to the
displays on normal Sony home MD decks. The case is surprisingly deep.  On
the rear panel is a non-detachable mains cord, two mini phone jacks wired in
parallel for the Control A1, a TOSlink optical output, 2 TOSlink optical
inputs and 4 RCA jacks for the analog line inputs and line outputs.

The deck itself is electrically very similar to the JE520 in my stereo
system.  It uses ATRAC 4.5 and produces 20-bit digital output.  The front
panel controls are very limited (there's no menu button, for instance), but
all of the controls that I have come to expect on a home minidisc deck are
available on the supplied IR remote.  Operating the MDS-PC2 from the remote
is almost identical to operating the JE520.  Most features I tried operated
flawlessly, however the A-B erase mode (which I use to trim off the excess
recording at the start of the song) seemed to crash when I tried to move the
"B" edit point forward a frame with the >>| button.  While not essential for
playing discs, the remote is needed when recording if it is necessary to
access the level meters (with the display button on the remote) or adjust
the record level.

The computer interface is a small box labeled "Vision Touch CAV-50C".  It
has an attached 1 foot cable with DE-9F for connection to the computer's
serial port and a single mini-phone jack for connection to the Control A1
cable from the deck.  It contains an NEC 78082GA26 single chip CPU, a Maxim
3221 RS232 interface and various other parts.  It requires no external
power; it is powered by the DTR line from the computer.  The interface only
works with a normal PC-type serial interface; it will not work with
high-speed PCI serial cards.

The installation instructions suggest using analog audio connections to the
computer.  At first I thought this strange, but given the experiences I've
had the past few weeks, I can see that they do this because they can be sure
it will work.  I have been unsuccessful with connecting the S/PDIF output
from my Samsung SC140 CDROM because it, like most other CDROM drives, only
outputs valid S/PDIF data when playing, not during stop, pause or seek.
This is unusable with Sony's drag-and-drop software.  The digital inputs on
the MDS-PC2 seem also seem to have a problem accepting 16-bit S/PDIF from my
M Audio DIO2448 sound card, although the DIO2448's S/PDIF input does accept
the MDS-PC2's output (at least 16-bits of it; Cool Edit 2000 is prone to
skipping (probably needs something faster than my 433 Celeron) if I use it's
32-bit mode, which is necessary to completely capture to 20-bit output of
the MDS-PC2).  The MDS-PC2 *does* accept the 16-bit S/PDIF from the CS4299
codec on the computer's motherboard.  Sound confusing?  That's probably why
Sony recommends analog!

The PC software comes on a CDROM along with a label making program and a
user operation manual in PDF format (the only written instructions that come
with the software are the installation instructions).  Installation is very
simple, just insert the disk and click on the install buttons.  Operation is
fairly intuitive.  Upon starting the MD program, you are presented with a
"remote control" bar that has title readout, running time, and play, stop,
next track previous track buttons.  There's also a unit select drop down box
on the left that allows you to select the device you're controlling: the MD
deck, the CDROM drive (PC CD) or an external CD player (via Control A1).
For more complex functions, there's a drop-down button on the right that
brings up an "edit" menu bar with, from which you can select the MD edit
window, an edit window for an external CD player,
an edit window for the CDROM player, an edit window that has the external CD
and the MD for drag-and-drop copying from CD to MD and an edit window with
the CDROM and MD for drag-and-drop.  Some may find mildly annoying the fact
that *all* windows in the program are fixed size and cannot be resized, but
usually it's not a problem.

Hands down, the best feature of the MD edit window is the track titling
feature.  When a minidisc is inserted, the existing title information is
read from the disk into the title area of the window.  Not only can you
enter/edit titles from the keyboard, but you can prepare a file ahead of
time with 1 track title per line, copy it to the Windows clipboard from the
editor (notepad, for exampe) and paste it into the track title area of the
MD edit window!  Right click and you can save the track window to a CSV
file.  Buttons for all the minidisc editing features like A-B erase, track
erase, move, etc. are there.  They generally work well, however I must say
that I prefer doing A-B erase on my JE520 using the jog knob; its a lot more
precise than the slider window in the MDS-PC2's program.

Although I don't have an external CD player with Control A1, they seem to
have put a lot of thought into the CD window.  It can control a multi-disc
changer as well as a single disc player.  It, like the MD window, has a
title area that can be edited.  I don't know whether it stores the titles in
the player's Favorite Track Select memory or in a file on the computer.  The
CDROM editor window is just like the CD window, although the manual doesn't
give any indication that it can control multiple CDROM drives or multidisc
CDROM drives and I only have one in my system so I couldn't experimentally
determine this.  In any event, it operated the CDROM drive flawlessly.

The final 2 windows are the CD to MD and CDROM to MD drag-and-drop windows.
They allow you to build compilation disks track by track.  After you've done
the drag-and-drop to indicate which tracks you wish recorded in which order,
you can hit "Start" and the program will do the rest.  It even copies the
track titles!  However, it appears that all tracks must be recorded with the
same record level setting; there's no provision for adjusting levels on a
track-by-track basis.  Some may be disapointed to learn that all copying is
done at 1X speed...  I've not tested drag-and-drop window yet because of the
previously mentioned S/PDIF problem with my CDROM drive.  While this is a
common problem with CDROM drives, I think it is very rare with audio CD
players.  That, along with the multidisc capability, is probably why Sony
added the ability to use an external CD player.  (Hmm... maybe I should
think about getting a CD changer!)

The final button on the MD edit window is the "Print" button, which launches
the label maker program.  I haven't done much more that print a sample label
to see what it looked like...  It produces a disc label, a case label and
two edge labels.  As expected, very small print due to the MDs small size.
The label program has a way of putting graphics on the label, which I did
not try.  But it looks promising...
