Pinout /manual for the a1200 z4 board

[Eco]

I've recently acquired a Z4 board for my A1200. The Big Book of Amiga Hardware identifies it as the "Elbox (Power Computing) Winner / Zorro IV Busboard".

However, the board did not come with any documentation, and I guess I should power it using the power connector on it, marked P8/P9. The trouble is, I've been unable to locate the pinout of the connector. Do you know the pinout? Is the connector some standard one?  It kind of looks like a standard AT connector..   :-?

While my system does work with power connected to the standard A1200 power connector, my XSurf 2 does not work in any slot on the Z4, I keep failing the 16 bit memory test when running xsurftest. I know the jumper settings of the Z4, they are correct for my BPPC (all open).

Zadoc, I sent you a private message.

I hope powering the Z4 through the p8p9 will make the X-surf work. The connectors appear squeaky clean, but better get some IPA then..

I have already tried the X-surf with my Mikronik Z2 board, but it was a no-go. Jens suggested that I get myself a Z4, so I did  :-D

On the Micronik, the xsurftest would complete successfully without my BPPC attached, but that does not happen with my Z4 currently. That's why I think it could be a power issue.

For the record, my A1200 is rev 1.d4.  I took it out of the box to do the timing fix, but to my surprise it did not have the 123C and 125C resistors; just clean solder points with nothing attached. Too clean for anyone to have already done the fix; they were not there to begin with.

Adding the  board adds one line to the expansion list and does not change the existing one. Both expansions are reported as working, so I take it that it's not the autoconfig then.

Thanks to Zadoc, I have the manual now, and the jumpers are correctly set for my BPPC accelerator. In addition to the xsurftest not completing successfully, I also noticed that when I have the xsurf installed I get corrupted pixels and lines on my display. I don't get them if the card in not installed.

I'll get an AT power supply with the plugs intact very soon, I guess my problems could very well be solved by powering the thing up propely  :-D

Follow-up: X-Surf sent back to shop, will be getting a new one.  Jens Schönfeld was very helpful and prompt in corresponding with me and helping me find out the problem. Seems very much like a faulty data line in the card; could be a solder point, or something to do with the realtek chip.

The card has a two year warranty, which is nice.

Some more follow-up: I finally got the card back, and it tested fine in Jens' lab. Jens did some cleaning on its connectors though, and now the card consistently passes the xsurftest if I disable my BPPC by holding down "2" during boot. This happens both with my ZIV and Micronik busboards.

So the problem has something to do with my BPPC then. It's the 040/25mhz & 603e/200mhz model. Any ideas?

Thanks but I already have the manual, courtesy of Zadoc. Maybe I should make a new "fix my xsurf" thread out of this..
