A1200 Busboard problems

[locutus]

Hello, i recently got a A1200 machine in a Micronik tower and a Micronik busboard.

I am powering the machine over the floppy connector and the machine works (well, the insert disk screen comes up and i can get to the early bootup menu) the Blizzard 68030 board also shows it's blue lines on bootup, so i presume that one boots up to.

So i added the busboard and stuck some Zorro2 cards in it (a Picollo (in Z2 mode), a Xsurf and a SCSI board.

the chips on the Zorro boards get warm (well, only the Cirrus Logic chip noticably heats up) , but when i go to the early bootup menu and check for any expansion devices it only shows up one board (which is the Blizzard i strongly presume, because it goes away when i remove that)

There is a socket on the Micronik busboard (for some largeish DIL (??) IC, it's unfilled tough) .

Anyone got some idea's advice ?.....

i think it is this http://www.amiga-hardware.com/micz2i_front402_big.jpg busboard, but the chip with the sticker on it is missing.....

Drivers for those Zorro cards aren't really a problem, the Picasso is supported by P96 and i have a disk with SANA drivers for the Xsurf

It does not, it got some custom connector to which i dont have a fitting plug.

I now have a A2000 PSU feeding the Floppy port, i also got a A500 supply, couldn't i just connect -both- ?

Then how is it possible that the LED on the Xsurf burns, and the Cirrus Logic VGA chip gets warm ?

Okay i solved the powering problems by adapting a PSU for the external connector, now that's done it still wouldn't work, so i started to inspect the board itself a bit.

what turns out 3 sockets are empty, i found a picture of the original board on TBBoAH

the most left chip with the Sticker on it is missing (is this a UV-EPROM ?) and the 2 left most chips, 2 GAL's (are GAL's programmable logic chips, or am i mistaken ?)

is it possible to replace those chips, or are those extra or something ? :/
