_ Sirmo Miss Americana _ The three known versions of this game are
all very similar and it’s my guess that they use these same pcbs and modules`
Anyway, this will help get us started`…an
upper-case Triple Bonus One day Larry and I were talking, and he
had his Bingo opened and wondered if I wanted any pictures`…smile`
Now this first image of the CPU answers
an important question for us`…how the Belgium guys will also refer to these
machines as Miss America
Yep, I sure do` From: Larry Lemmerman <> 1.cpu...pcb28 C 2. Power Supply...pcb 43 D....upgraded from ver. C 3. Transformers from left rail...Right is 110v to 220v step-up
...left supplies AC to power supply and motors... 4. Ball Trough.. From: Larry Lemmerman <> 1. Ball drop tray... 2. Body split..Pcb.33 3. Shutter/playfield bottom view 4. View of body cavity…. Playfield From: Larry Lemmerman <> Here is the start of the Sirmo Miss Americana triple bonus break down
and how they work in American....LOL....As you can see 9 steps with 4
colors..now uncovered we see # 47 lamps with standard Bally sockets. In the
closer view you can see the 4 Stars on the Extra card (Orange Scoring)
also note the missing 4 Digit board...Here it is..the front is 4 ea. Man6760
led displays mounted on the pcb 44 board...As we fold down the front we see
the 5 motors that drive the slides for the numbers that move horizontal.
Finally in this e-mail here is a look at the "Magic Motor"
driver board (pcb34 A) this board takes data from the Mpu board thru the 16
pin dip ribbon cable at the bottom of the board. The relays at the top drive
the motors. Please note that in close-up board is rotated 180 degrees..T-1
thru T-5 are triac's or 50vac switches. Once triggered a triac will drive a
motor until the ac circuit is broken.... From: Larry Lemmerman <> Ok... Here we see the dip switch board (pcb 42) used to program the
features of the game...it plugs into the I/O board (pcb 28) but gives
addresses to the cpu program...To the left of the dip sw.board is the
sound board (pcb 072) lower plug goes to the sound coil ...upper plug is
power and the driver signal. 47jpg is of the I/O or interface board
(pcb 32c) which shows the driver transistors(2N3771) on the right
side... TO-3 cases except the bottom two which are regulators. The
wiring to the left is part of the lighting matrix...on left are the cables
that go to..J5,,body board......J7,,Dip switches http://bingo.cdyn.com/machines/sirmo/miss_americana/resources/manual-miss_americana.pdf http://danny.cdyn.com/mcana1.htm Thank you Larry Here are a few from an old “sales ad”
spotted in 2022
Notice how this is the Lower Card version of the game from that same
Era Basically the same CPU, but a slightly different version`…check the
eproms and daughter card - etc` http://danny.cdyn.com/Section11b1Sirmo.htm _ Finally, some
detail on the Magic Lines _
