Marble Madness Cartridge - ROM position on LSI version

Archived from groups: rec.games.video.arcade.collecting (More info?)

Guys,

I really need some help here.

I am trying to figure out the correct position for the ROMs in a LSI
version Marble Madness cartridge. There is absolutely no information on
this version online.
The scanned manual found online is only the TM-276 (1st printing) that
only contains information on the TTL version (the second revision
TM-276A has never been made online aparently).
There is nothing I could find in the RGVAC archives as well. Just other
people begging for this information since the 90's without a response
(not through the newsgroup anyway)

Is there anybody with a LSI MM board could check and send me the ROM
positions ?

Also, if anybody out there has either a working MM daughter card (TTL
or LSI) or a copy of the TM-276A manual for sale just let me know.

Regardless if I get it through this post or not I'll make a promise
here. If I am ever able to get this information (ROM positions or
hardcopy of TM-276A) I will make it available online, so nobody has to
go through this again.

Thanks in advance,

Breno

Dave,

Thanks a lot. I had seen an old post in RGVAC that had this
configuration, but the author was not sure and trying to confirm the
information. I was not sure how reliable this was. Thanks for
confirming it.

With that settled, I need to find the ROM images for the EPROMs on the
left side of the PCB since their are not available in any of the four
MAME rom sets in existence. These would be:

ROM Position in PCB

136033-109 = B1
136033-115 = B2
136033-111 = C1
136033-117 = C2
136033-113 = D1
136033-110 = A6
136033-112 = B6
136033-116 = B7

Does anybody have these images available or is willing to dump them ?
