The motherboard is Zida Tomato 5STX-512. There are two strange connectors between the PCI and the ISA slots and there are no details for them in the user manual. I have this motherboard since 1998, but never used this connectors and I still don't know if they're related to PC-PCI connectors. The board was part from pre-build full computer configuration, so I don't have any proprietary cables for these connectors. I have only serial port, parallel port and PS/2 connector brackets with their standard cables and the original paper user manual for the board. Now I've soldered pin-header for JP6 connector as it was missing originally and checked for signal connections between JP6's pins and JP7's pin, but there are none, except for the ground pins (marked in blue on the picture). Also there are no +3.3 V or +5 V pins on both connectors. Any ideas what are these JP6 and JP7 for?

Do a search for MB_PRO connector and you should have your answer.

Primary use is to connect a Sound Blaster card to a Modem Blaster card.

Thanks for the info! The pinout in vogons wiki don't match all the ground pins for the Zida's "PCI media interface" connector, but seems like it's mostly the same - for some nowadays useless Creative modem cards. I was hoping this one (PCI connector JP6) to be some kind of propriatery PC-PCI connector, but no luck. Maybe it will be of use as front panel AC'97 connector when PCI sound card is installed.

I can't find any pinout diagram for the ISA JP7 connector, but probably it's as useless as its sibling JP6.
