busboard woes

[lorddef]

Well I've just rehashed my Eyetech mk3 tower so that I can fit a busboard in it and now my busboard is being a git.

I have an a1200 (1.d4 with timing fix) powerflyer and a blizzard 030 board, 3.1 roms.

Everything is fine when I run the above setup alone.  But when I remove the accelerator and fit my MicroniK 6860 rev 5.43 busboard all I get is a red screen on bootup (I believe this means bad rom?) and the power LED flashes on and off a few times before it reboots again and does the same. If I install both the bussboard and my blizzard card all I get is a black screen when I power up.

Does anybody know why this is? or does anybody have this busboard running?

The busboard has an 8 pin connector on it  which I believe is for power, but I am led to believe that this is not needed if I'm getting my power form the Eyetech PSU. Is this correct?

Uh this is beginning to annoy me now.

cheers Vincent!

Now then, who knows the pinouts to this 8 pin connector on the MicroniK busboard?

First person with a complete listing gets a prize!

I'm already using the AT PSU to power the a1200, malthought I'm doing this thropugh the floppy port and then supplying 0v through the original a1200 power jack.

@ lempkee Where did you get a conector form to attatch to the one on the busboard? its not AT or ATX.

I already had that manual you lot are looking at, but the power connector in the diagram is upside down compared to mine and it's a slightly different board, so I'd like to check up on the pinouts.  Secondly that same manual also says its okay to power the board off of the a1200 mobo.

I'll need to verify these pinouts and find a power connector to wire up.

[lorddef]

defo not!

each of the two AT connectors have 6 connections, and this is an 8 pin connector.

cool, cheers Matt_H, it sounds like I'm gunna need your help in future.

does your bussboard look like this?



If so I think your pinouts are spot on.

[lorddef]
