Sega Model 2/Model 3 Jumper Configurations And Security Board Info

[twistedsymphony]

Whenever Model 2 or 3 conversions come up the biggest problem usually ends up being unclear on the proper jumper configurations. So I've started a spreadsheet to capture this:

https://docs.google.com/spreadsheets/d/1X0yhBgxWGy56PX7o1nM0SoOtj4pfSgu5r3gYe_EGfTU/edit?usp=sharing

There is still a lot more to be captured / if anyone has jumper settings to add or finds any errors let me know.

---------------------
Some useful information about Model 2B ROM Board jumpers:

JP03/04/05/06 never seen a different configuration for those
JP13/14 CPU eprom size
JP15 Main Data Size
JP16/17 always the same configuration
JP18 Polygon eprom size
JP19 Texture eprom size
JP20 Co-Processor eprom size
JP21/22 Audio PGM eprom size
JP23 Sample eprom size

Hi
I have some Model2 / 3 boards i can take pics of 'cause i dont quite understand jumper codification in the spreadsheet.
best

i dont quite understand jumper codification in the spreadsheet.

it's just the jumpers in order. so: 31-3111-313311111-11-1-13-11-3

is:
3 = JP1 2&3 jumped
1 = JP2 1&2 jumped
- = we're moving to a new jumper bank
3 = JP3 2&3 jumped
1 = JP4 1&2 jumped
1 = JP5 1&2 jumped
1 = JP6 1&2 jumped
- = we're moving to a new jumper bank
3 = JP7 2&3 jumped
... etc.

so which jumpers are we talking about ? all boards? the ROM board? the CPU?

Top ROM board on Rally championship Twin:

JP1-2-3-4-5-6-7-8-9-10-15-18-20-22-23-26-27 : 3
JP11-12-13-16-17-19-21-24-25: 1


top ROM board on Virtual Fighter 3

JP 2-3-4-5-6-7-8-9 : 3
JP1-10 : 1

Just the ROM board. AFAIK the CPU board jumpers aren't game specific... but maybe someone else can confirm.

Which version of the game are these? these were released on multiple hardware versions.

Very cool on deriving the jumper config too.

 

[nnap]

All settings are for the 2b version.

Can you double check these two, they don't match the PCB photos I've found.

the only difference in Pilot Kids is the co-proc jumper. As the co-proc area is not populated, it does not matter. So both setings will work.

Your last bronx picture is of a Indy 500 rom board.

added Virtua Fighter 2, 2.1 (same) and Dynamite Deka (2A), Fighting Vipers 2 - thanks for putting this together!

looking at the picture I think you have some numbers backwards there (JP17-JP23), the 3 and 1 position aren't always on the same side of the jumper

Here are pictures of my Over Rev (2B). The board's number is 836-13275.

Man ur right thats:

my bad

 

[twistedsymphony]

are the 4 after that also correct?

 

[davidcoolman]

I swear I triple cheked

 

[twistedsymphony]

you're right, I was looking at it wrong

it's been added!

Can you tell me how to set jumpers from 2 players to 1 player ? I have a indy 500 that does not work without it's twin.
