Ronin Imtronics Hurricane 1000 power question

[Terse]

Hi,

Does anyone know the voltage for the Ronin Research Hurricane memory board for the 1000?  It's got a 2-pin connector that looks like it would have connected to the 12v line via a molex splitter or something.

Anyone have experience with this part?

Here is some info;

Hope this helps some...

Here is another link - but still no word on voltages

Thanks for the links, but am I missing something?  this appears to just be a photo and specs.  No mention of how to power the board.

You can submit questions to the BBOAH. Maybe they can steer you to an answer.
It has been so long since I have seen one of these installed in an A1000, I am not sure of the connections. IIRC, the lines from the RAM board connect to the CPU board. This still doesn't help you with the voltages however.
I've asked some Amiga people locally - maybe we will get an answer from this source.
Wish I could be more help.

Thanks!

I may see about mailing them.  I've asked A1K.org too. I know they sometimes deal in exotic hardware.

The board almost certainly connects to the main PSU somehow.  It's already connected to the Ronin Hurricane 1000 board with a massive 96 pin connector

I have my doubts that that is for power, but if it is it would be 5v. 12v would most likely kill it. Check what it is connected to before you connect anything to it.

It may not be for power... I'm basing my assumption on this blurb in Compute magazine:

Ronin H1000 | Amiga 1000 | 1MB-4MB  | 1-yr. warr |  $600 (1MB)
Internal board for use with the H1000 accelerator board; includes adapter harness for power supply

I can say this about the card:  It looks to be in perfect condition.  The Hurricane it came with does work (had a broken pin but easily repaired)

The machine will not boot with the RAM board installed.  It doesn't even try.  I don't think it's broken.  I think something is missing or mis-configured, and that leads me to the mysterious 2-pin connector.  It's keyed as if it uses power somehow.

Might be worth following the traces and seeing what pin(s) on which chip(s) they lead to, and then looking up those chip pinouts to see if they're for power.  I'd guess one pin would go to ground.  I like guessing.

The TL7705A chip located near the connector is a 5 volt supply voltage supervisor. If that connector is for power, then the +5v pin should be connected to pins 7 and 8 on the chip and the ground pin should be connected to pin 4 of that chip.

It does appear to need a 5v line.  I ran one from the molex power connector of the floppy into the card and now the system boots with the card installed.
It's not clear if the card is working.  It's not an autoconfig RAM card and it looks like it uses its own custom memory config util. The good news is that the Amiga HW ref guide has this file so as soon as I figure out how to get it onto an Amiga floppy I can test it out.

Win!
