MicroProcessor-Controlled Jukeboxes
Seeburg introduced the
industry's first MicroProcessor-controlled jukebox in 1978, the SMC1. In
actuality, all Seeburg jukes built after 1978 were controlled by a MicroProcessor, but I chose not to show any of the CD machines. All the other
manufacturers followed suit, introducing their versions as time progressed. By
any 'official' accounting, all machines featured here are still members of the
Console Era (along with all of the
Digital jukeboxes) but I choose to display them
separately. Please note that the year
listed below is the year in which the machine was first produced.
The machine would have first been built in the fall of that year, and considered
to be the following year's model.
MicroProcessor
Survey: I'm hoping
you can help me with a survey. I'm trying to determine
how many different programs Seeburg used for the 3870 Microprocessor these
machines are controlled by. If you open up your MCU and remove the Pricing Board
(the one with all the jumpers, or, alternatively, a four-position mini-switch on
it), you will see a fairly large chip (40 pins) with '3870' written on it. There
will also be 'MK' or 'M', followed by a five digit number and maybe a letter. This is
the ROM pattern number. Also, there will be a four-digit number starting with
78, 79, 80, 81, etc. This is the date code. I would really appreciate it if you
would email me with both the pattern
number and the date code. After I get a reasonable number of responses, I will
post the numbers on this website. Thanks in advance!

SMC1 Disco 160
selections, 45 RPM.
Introduced fall, 1979.
A completely new cabinet design, with a completely new
Pricing and Selection system, the MCU MicroComputer, using a
single-chip microprocessor. Here, the tormat is replaced by chip
memory on the CPU board. Customer credits and the now-playing
indicator were on a digital display, just to the left of the
selector keypad. A small spotlight reflects off a jewel glued to the
turntable, catching the eye as a record plays. This is the 'glint'
visible between the red/magenta/blue circles and the upper chrome
piece in the photo.

Seeburg
SMC2 Phoenix 160 Selections, 45 RPM.
Introduced fall, 1979.
This machine is a facelift of the SMC1. Very
few of these were built by Seeburg, as they went bankrupt shortly after
production began. It
can be distinguished from the later Stern/Seeburg SMC2 Phoenix as having
the vertical speaker panels in brown, rather than orange (see below).
For the Seeburg version, the disco ball rotates whenever the machine is
on, but here the lights are on only when the mechanism is running.

Stern/Seeburg SMC2 Phoenix 160
Selections, 45 RPM.
Introduced fall, 1980.
This machine was
built by Stern after acquiring Seeburg during the bankruptcy sale. The
main difference is that the vertical speaker columns are orange, and
that the disco ball is always on and lighted, rather than the lights on
only when the mechanism is running as in the Seeburg version, pictured
above. One of my first tasks after the Seeburg buyout by Stern was to
redesign the MCU's CPU board, to incorporate bug fixes, and to make the
board easier to manufacture. Generally called the 'Sternburg' SMC2.

100-79M DaVinci
100 Selections, 45 RPM.
Introduced fall 1979?
Little known and quite rare 100-selection machine using
the MCU system. Probably only 100 or so were built, mainly for export.
The cabinet and graphics are identical to
100-78D Celestia. Only minor
changes were made to the selector panel to accommodate the MCU digital
display. Even though I worked for Stern/Seeburg at the time this machine
was built, I did not know of it until 2003, when I received an email
asking a question about it. This machine was also known as the SMC1 Jr.
For more information, please refer to the
SMC1 Jr. article.

VMC1 Video
Music Centre 200 Selections, 45 RPM.
Introduced fall, 1981.
Built by Stern/Seeburg. A completely new
cabinet and selection concept, using a video screen to display record
titles instead of the old paper title strips. This was the last
200-selection machine built by Seeburg. In my opinion, it has the best-sounding
amplifier and speaker system of any jukebox ever built. It was a failure in the marketplace; only about 300 were built,
and many of these were exported to Europe. There was also to be a
video Wallbox (no built-in speakers) offered, with a monochrome screen, which
worked identically to the color Console screen. The controller board was
interchangeable between Console and Wallbox. A working prototype of
the Wallbox was built, but I don't believe production ever started. Click here
for a photo of the VMC Wallbox.

SMC3 Prelude
160 Selections, 45 RPM.
Introduced 1984
Built by the Seeburg Phonograph Company, started
by a group of outside investors after the Stern bankruptcy. It used the same cabinet as
the SMC1 and SMC2. In this version, the Disco ball was replaced by lamps
mounted on stalks protruding from the rear of chamber, giving the effect
of floating in space. They
blinked in time to the bass and treble notes in the music. When no
selection was playing, they stayed on with no blinking, similar to
the color organ kit which was to be offered as a field modification to
the FC1. This is the last machine to use the MCU, and Seeburg's last vinyl
record machine, replaced the
following year by the first CD machine, SCD1.

Remote selectors (Wallboxes and
Consolettes) were available for all Seeburg coin-operated jukeboxes, permitting
a selection to be made from the privacy of your booth, rather than approaching
the console itself. Also, 'Hideaways' (a plain box containing the mechanism and
selection receiving circuitry) were available to replace the console. While not
flashy like the console, these machines were certainly cheaper and could be
placed somewhere out of the way, in a closet, for example. To see the remote
selectors, click here.
