The Computer
Category: MAME'd Millipede :: 3. Electronics
The computer I ended up using for this project was a several year old Dell OptiPlex I have had around for projects.
Here are the basic specifications:
| Processor: | 500 Mhz Pentium III |
| Memory: | 256 MB |
| Storage: | Western Digital WD400 - 40 GB |
| Graphics: | ATI Technologies 3D Rage Pro AGP (rev 92) |
| Audio: | Creative Sound Blaster 32 PnP |
| Network: | 3Com 3c905B 100 Mbit Ethernet |
This is definitely not a powerhouse machine, but it is more than adequate for the task. I keep it connected to the network for making adjustments to the software and because it has the resources to continue to act as another server in the house for various tasks (mostly storage space).

I removed all of the relevant components from the computer case and installed them inside the MAME cabinet. This includes the power supply, motherboard, hard drives, fan, and the tiny power/reset button card with the power LED.
For mounting I decided to take a page from the original Millipede cabinet design and slot two pieces of wood to use as holder for the motherboard. The power supply is fastened directly to the inside wall and everything is arranged in close enough proximity to be within the length of the cables used in the original PC chassis.
I placed the fan on top of the Pentium III heat sink and mounted the little power control board near the OptiPAC interface card. It's somewhat bizarre looking, but it makes the entire system self-contained and certainly gives the system adequate airflow. I now no longer have a PC sitting in a case just outside of the Millipede cabinet.
I leave my system on 24-hours per day so the the machine is playable just by turning on the monitor using the power button I installed just under the control panel (discussed in Control Panel: Final Touches).
This is the CPU mounted inside the Millipede cabinet on the left wall. The original Millipede board is still mounted on the right wall and was the model for the board holder. It's not as chaotic as it looks. :)
