I have two of these setups running. I'd estimate a couple hundred or more games worth. It was with a bit of horror that I was greeted with the YOU'RE SCREWED [paraphrasing] message at boot up indicating that memory had been lost and there wasn't anything in memory to actually load. Basically, by the time these systems came out the folks at Sega had realized that having a system which required constant loading from a CDROM/DVDROM/GDROM device was putting way too much strain on the mechanically driven drives… having seen a higher number than usual of service calls related to these devices going down on other systems. Since the time I installed this in my Outrun 2 cabinet we HAVE had at least 2 power outtages including one a couple days ago that lasted about 20 seconds. What they came up with was a rechargeable battery system that retains the data loaded from the CDROM/DVDROM/GDROM on RAM while the system is off so that when it's powered up, the info is loaded from the RAM rather than the much slower and much less reliable disc drive. The additional wire is a fan speed/pulse wire. I play my games more than I work on them. The system works great for games on location being they are on 8-12+ hours per day and off usually no more than 12 hours or so. ),  solder a blocking diode to the positive lead with the "line" on the diode facing toward the plug (this is necessary to prevent the charging current from the game pcb from sending a current back in to the regulator) then screw the leads (with diode in place) to the voltage regulator. I work on my games more than I play them. That said,  don't hold me to that estimate. Search for CGR18650, or just 18650 and you should be able to source some locally. The OEM fan/heatsink is a "109p4405h8016". Regardless of satellite mode, boards with ethernet listen on UDP port 17185 which is VxWorks WDB. So,  the way to handle the issue of blackouts is by adding a PicoUPS. As any owner of a Sega NAOMI/NAOMI 2 with GDROM (or Netbooting), Chihiro or (I believe) Tri-Force systems will tell you… one of the bigger pains in the ass is the battery system that was used to retain data while the system is off. After attempting to charge the battery both through the Pico UPS in the backup system and even via a dedicated 12v charger,  the best I could get the battery to charge to was 8v… and even then I could watch the voltage drop over time. A working replacement is the Noctua nf-a4x10-5v - make sure you get the 5V version. Here are a couple diagrams to help you free yourself from the dreaded battery. Each time I checked the Outrun 2 machine and the game loaded right up. This page was last edited on 21 June 2015, at 05:29. You can find necessary parts for this project below (all Amazon.com links): 1N4007 Blocking Diode They are located in a cluster of 3 (JP3-JP5), beneath the battery, opposite side of battery connector. The majority of it was sitting at about 40 degrees from the socket. THANK YOU! As I pulled the game away from the wall the answer was apparent. 16,770,000 (24bits) Polygons : 2.5 Million polys/sec Rendering Speed : 500 M pixel/sec Additional Features : Bump … Time for a new battery. I use the simple version above in my NAOMI as I add my high scores to my digital high score board and it's not a big deal to lose the high scores and since the NAOMI is setup to netboot from my MAME cocktail,  it's very easy to re-install a game if the power goes out. The problem with the system arises when the game is in a home setting. The H is probably some rating, I used CGR18650CF's which have a bit better capacity. Speed is 38400,N,8,1. You will find links to these parts (and to others I'l be talking about) at the end of this post. //. It is a 5V and 3 wire and actually needs to be 3 wire. If you want to go REAL cheap,  you can get the version without the voltage indicator for $5.80 plus free shipping… though for both my projects I used the $9.00 variety.

That sucked. I've seen this when the daughter board on the DIMM is not properly seated. Lying on the floor behind Outrun 2 (and between it and Need for Speed) was the 15v power transformer plugged in to the extension cord that plugs in to the wall. What you do is clip off the end of the wall-wart transformer… screw the leads to the input side of the voltage regulator,  then snip off the wire & plug from your battery pack (you won't need that silly thing anymore!

When booting from compact flash, you get this if the card is corrupted. To enable satellite mode on DIMM boards, jumpers on the DIMM board must be set to: Network wise, this will enable TCP port 10703.
