# Hardware
|
|
|
|
The hardware that makes up the WACCA cab is an interesting amalgamation
|
|
of completely custom parts and off-the-shelf components. Here's some information about it.
|
|
|
|
## ALLS HX
|
|
|
|
The ALLS HX is a specialty PC designed by SEGA for use in arcade games.
|
|
It is the brain of the cab, actually running the game.
|

## Power Delivery
|
|
|
|
```text
|
|
LFA150F-12-J1 150W 12V 50-60Hz 12.5A IN AC100-240V
|
|
LFA150F-5-J1Y 150W 5V 50-60Hz 30A IN AC100-240V
|
|
```
|
|
|
|
|
|
|
|
These two units supply all the power needed for the PCB components (sound system, LEDs, touch controller etc).
|
|
My photos will look a little different at the bottom as we had to jerry rig an extension cable to feed power into the unit since I don't have the original cabling for it. Works fine on American power, there are also reports of it working fine in Europe.
|
|
|
|
R1 uses a 300VA but that's probably overkill.
|
|
|
|
|
|
|
|
Hits about 200W during attract mode.
|
|
TODO: power info during songlist pull etc.
|
|
|
|
## Touch Boards
|
|
|
|
There are two of these and they each process 6 segments. Together they control the two halves of the touch controller assembly (for a total of 12 segments).
|
|
|
|
|
|
|
|
Each segment of the touch controller is connected to the others with the help of RS485 through a ribbon cable.
|
|
The PCBs present on each segment are the exact same with the addition of a custom Pentel IC and some extra components needed to drive the tactile sensor array.

## LED Control Board
|
|
|
|
It sends the pretty colors to the touch controller.
|
|
|

|
## 2.1ch Amp
|
|
|
|
|
|
Handles analog sound routing to subwoofer and tweeters
|
|
|
|
## Headphone Amp
|
|
|
|
|
|
Handles audio output to the control panel
|
|
|
|
## I/O Control Board (837-15257-01)
|
|
|
|
|
|
The existence of this board is a bit overkill for what it's used for, likely it *had* to be used due to SEGA producing the cabinets for Marvelous. This is a newer version of the control board that has a USB port on it, almost all sega cabs use this now.
|
|
|
|
*Note: WACCA does NOT check for a coin counter, so the resistor trick is not needed to apply credits in game.*
|
|
|
|
## Control Panel
|
|
|
|
This giant metal LED lined panel has [4] plugs that connect to
|
|
|
|
1. Card reader
|
|
2. VFD display to show IC readout for cash cards. Mine had some burn in. *Unused.*
|
|
3. Headphone amp jack with VOL UP and VOL DOWN buttons
|
|
4. All the LEDs
|
|
|
|
The coin entry stuff connected to the cash box is here too.
|
|
|
|
### Card Reader
|
|
The Aime card reader is model number **610-0955**. There are lots of good solutions to DIY one of these.
|
|
|
|
## Touch Panels
|
|
|
|
The touch controller assembly is composed of 12 segments divided into two halves
|
|
(6 per side, each having their own main controller board). They each have an individual channel ranging from 1 to 6.
|
|
|
|
|
|
|
|
Each one of these weighs 1kg (2.2LBS) *(870g if the metal bracket is removed)* which totals to about 12kg (26LBS).
|
|
|
|
|
|
Each unit has 5 LED strips (each strip has 8 LEDs making for a total of 40 LEDs per segment).
|
|
In total, there are 480 LEDs in the touch controller assembly
|
|
|
|
The sensor array is made out of 5 columns and 4 rows amounting to 20 touch zones par segment.
|
|
All 12 segments amount to a total of 240 touch zones.
|

|
|
|
|
Somehow I never really understood how MASSIVE these units are until I held an individual segment in my hand.
|
|
|
|
|
|
|
|
Here are some scans of a segment that shows the curve profile.
