Digital Jukeboxes
Introduced in 1969, the LS3 was Seeburg's first
digital jukebox. The development took about two
years, and included the design of three custom integrated circuits. Two
were housed in a black plastic box (called, amazingly enough, the 'Black Box').
One chip took care of credit functions while the other took care of selections. The
system was designed to make it easy to attach the new style Digital Electronic
Consolette or DEC. To do this, all selections (even those originating from the
console) were encoded for transmission as though they came from a DEC. The
third custom chip (housed in a gray box, called -- you guessed it, the 'Gray
Box') decoded the selection and logged it into the Tormat memory. The system was
fairly complex, and Seeburg wanted to prevent competitors from figuring out how
it worked, so the boxes were sealed and had to be returned to the factory for
repair. They never published schematics for the boards inside the boxes or logic diagrams for the chips.
That information is available, however, in my book 'The
Seeburg Black and Gray Boxes', which includes complete schematics,
simplified logic diagrams, and troubleshooting
procedures.
Included on this page are the
two 100-selection machines using the CSP1 or Red Box, designed by me. These machines are the
100-77D Topaz and 100-78D Celestia.
While these machines did not use the custom chips, they did use digital logic
chips. 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. The prices listed below came from a Seeburg
Phonograph Reference sheet, which was basically a sheet listing various features
of each machine.

LS3 Apollo 160
selections, 45 RPM native, 33⅓
RPM with Auto-Speed engaged.
Introduced fall, 1969. Price:
(September, 1969) $1545.00.
The first Seeburg Digital jukebox, introducing the Black and
Gray boxes. Seeburg's marketing name for this new selection and
pricing system was
'Microlog'. The name was featured in all their manuals and
advertising, but in few other places. A more popular name for the
system turned out to be: 'Black & Gray Boxes'. The cabinet itself was a 'warmover'
(i.e., a slightly modified version) of the
LS1,
LS2-series cabinet design, which
had been around since 1967.
There was a
hideaway version of this machine (HLS3) available for USD $1295. A
hideaway is the mechanism, gray box, amplifier, and control center
in a plain cabinet, designed for use exclusively with Consolettes.

USC1 Musical Bandshell
160 selections, 45 RPM native, 33⅓
RPM with Auto-Speed engaged.
Introduced fall, 1970. Price (August, 1970) USD
$1725.
Features an innovative new cabinet design by
Bob O'Neil, his first effort for Seeburg. All of the following Microlog machines (and the 100-selection machines, starting with the
SX100) were styled by him. This
machine is quite stunning; it set a new standard for jukebox cabinet
shapes, featuring the extensive use of metal castings for cabinet
parts, in a manner similar to what was done in the jukebox 'gold'
and 'silver ages'.
A hideaway
version (HUSC1) was available for $1295.00

USC2 Bandshell Firestar 160 selections,
45 RPM native, 33⅓ RPM with
Auto-Speed engaged.
Introduced fall, 1971. Price
(August, 1971) USD $1695.
Facelift of USC1, limited primarily to cabinet
graphics and trim color.
A hideaway version (HUSC2) was available for USD $1295.00

SPS160 Olympian 160
selections, 45 RPM native, 33⅓
RPM with optional Auto-Speed engaged.
Introduced fall, 1972. Price
(August, 1972) USD $1695.
Completely new cabinet design, using many metal
castings. The graphics panels were also available in blue and
orange, in addition to the pictured magenta, see below. Every machine
I saw at the factory had magenta panels. This machine introduced
the SHP1 (Seeburg High Power) Amplifier, which had some early production problems. These
were resolved during the production run. Starting with this model,
the Auto-Speed was made optional.

FC1 Regency 160
selections, 45 RPM native, 33⅓
RPM with optional Auto-Speed engaged.
Introduced fall, 1972. Price
(December, 1972) USD $1795.00.
Seeburg's first attempt at the 'furniture console'
design, being pushed at the time by Rowe/AMI and RockOla. First use
of small 'grain-of-wheat' (type 2182) lamps for an eye-catching
display. These lamps were mounted behind a perforated, painted metal
screen, resulting in moving 'halos' of light as you walked by. I like
this machine so much I bought one from an Internet auction and restored it.
Originally, the trim (silver in the photo at left) was to be gold,
but that got changed prior to production. I once owned the prototype
machine, to which I added a color organ, making the lamps (which
were changed to red, green, blue, and white) blink in
time to the music. The color organ was a project I was involved in early in my
Engineering career at Seeburg, which never made it to production
because it was too time-consuming to install in a machine once in the field. Unfortunately, I sold the machine
when I moved from Chicago. If anyone knows the current whereabouts
of this machine, please email me.
This machine started Seeburg's trend of using many extrusion
sections as cabinet structural and trim elements.

SPS2 Matador 160
selections, 45 RPM native, 33⅓
RPM with optional Auto-Speed engaged.
Introduced fall, 1973.
Facelift of the SPS160, including new, chrome plated upper
speaker grilles and title strip holder surrounds. Quite an
attractive machine.

SPS2 Matador Quad Conversion.
Very few of these conversion kits were made. The conversion
was done in the field by the distributors and operators.

STD160 Vogue II 160 selections,
45 RPM native, 33⅓ RPM with
optional Auto-Speed engaged.
Introduced fall, 1974.
Previous
models made extensive use of cast metal parts for the cabinet
structure. With this model and the ones following, tooling budgets
became restricted. Instead, cheap extrusions were used wherever
possible, along with formed, spot welded, and painted metal panels.
First machine to use the
improved SHP3 Amplifier as standard equipment.

SQS160 Quadraphonic First Edition
This
machine used a Hafler Quadraphonic Decoder (which was actually just
three wire-wound volume controls mounted in a tamper-proof plastic box, connected
across the amplifier speaker terminals, and external speaker systems), along with
a different graphics panel. Otherwise, the SQS160 and STD160 are identical.

STD2 Entertainer 160 selections,
45 RPM native, 33⅓ RPM with
optional Auto-Speed engaged.
Introduced fall, 1975.
Same
basic cabinet design as STD160. The same lamps used in the
FC1 were
put into motion by a 5-bit Sequencer Electronic module designed by
me. The lamps were mounted behind mirrored glass in a
mirrored channel to give an infinity lamp effect. An off lamp travels
through a field of four on lamps (for a total of five) repeated in a sequence. The
illusion was that the off lamp traveled from the bottom to the top of the machine. The bulbs are difficult to replace, since their
leads are pressed into insulation-displacement contacts along with
the connecting wiring, using a special tool and a lot of patience.

STD3 Sunstar 160
selections, 45 RPM native, 33⅓
RPM with optional Auto-Speed engaged.
Introduced fall, 1976.
Same basic cabinet as the STD160. The front panels were
changed to a foam material, poured into a mold and allowed to
harden. After production started, it was noticed that the foam
tended to warp when exposed to heat or sunlight. Many internal
stiffening brackets were added to combat this problem. Foam was used
because the molds were VERY cheap, and resulted in a
cabinet, that while little changed from the previous year, looked
quite different. The design featured attractive silk-screened graphics in a
circular pattern with many-colored spokes, surrounded by a circular
version of the moving lamp display. The
lamp sequencer was carried
over from the STD2. Here, the lamps were mounted on Printed Circuit
boards, primarily due to pressure exerted by Underwriter's
Laboratories and Seeburg's operators. A secondary benefit is that they are much easier to
assemble initially and later to replace.

FC2 Hutch 160
selections, 45 RPM native, 33⅓
RPM with optional Auto-Speed engaged.
Introduced fall, 1976.
This machine used the same lid design as FC1, but the cabinet is now wood-grained,
with no lights other than the fluorescent lamp for the title strips. All
internal speakers were deleted, to be replaced by
bookshelf speakers
mounted on the optional hutch portion above the jukebox lid, shown
in the photo at left holding knick-knacks. If the hutch was not
used, extension speakers would be hung from ceiling brackets in the
establishment. This machine was very low production.

STD4 Mardi Gras 160 selections,
45 RPM native, 33⅓ RPM with
optional Auto-Speed engaged.
Introduced fall, 1977.
This
machine also has the same basic cabinet as the STD160. It is the last
digital (Black & Gray box) jukebox, and the last 160-selection
machine to use the Tormat. The moving lamp display is now in the center
of a set of three ovals, still using the same
5-Bit Sequencer.

A quadraphonic version of the STD4 actually
exists! According to Jason Sneddon, who contacted me about this
machine, the serial number sticker on the back of this machine says only
'STD4'. So this very rare version may have been a field conversion. On
the other hand, it may have been the same machine in the photo above,
and was a one-off conversion used for the publicity photo.

100-77D Topaz 100
selections, 45 RPM.
Introduced fall, 1977.
New graphics on the previous-year's SB100 cabinet. The
old electromechanical pricing and selection system of the preceding
10 years of 100-selection machines was replaced by the Red Box
System (a much simplified version of the Black & Gray boxes),
designed by me. The red box still used the Tormat memory.
|
 |
100-78D Celestia 100 selections,
45 RPM.
Introduced fall, 1978.
Yet Another facelift of the SB100
cabinet. This was the last machine to use the tormat, and the last to
use the red box. Note the almost identical appearance of the 100-79M DaVinci, following.

The last of the machines using
the Black and Gray Boxes was the STD4 Mardi Gras. The Red Box only ran for two
year's worth of 100-selection machine production, and the number of 100-78D
Celestias built was probably quite small. Both systems were replaced in 1978 by
the MCU MicroComputer system, covered next. Click
here to see these machines.
