Title: Amiga 3000 Rev 7 motherboard question
Post by: on January 15, 2004, 02:45:21 PM
I have a old Amiga 3000, actually it was the first that I got.  25mhz board, and this rev 7 board came with a rom tower.

     I am wanting to get this going again, maybe as my main machine.  Not sure how much better it would be over my Amiga 3000 16 mhz rev 9 motherboard machine.

     Can someone tell me if there is a way I could install 2.0 chips on this (or higher) without having to use the rom tower (which unfortunately now has a broke pin).   What setting and jumpers do I need to work on?

     Thanks!

I think you need to fix or buy another rom tower. I haven't heard of a way to replace the rom tower, or do away with it.
Maybe you can search aminet for a hack.
Good Luck!

   Why on Earth did they have the rom tower to begin with?  There are four rom slots there, regular ones like the Rev 9 has.  What was so different about Rev 7?

If I'm not mistaken you can just replace the tower with
ordinary roms for later rev a3k's. The early a3k's used
a special solution, loading the kickstart from the hdd.

but like I said, I don't think you need the tower... just a
set of 3.1 roms...

   Interesting!  So the 3.1 roms made up for the shortcomings of the earlier roms?  That would be interesting.  May have to give that a try.

     We did read something somewhere that some jumper settings had to be changed.  That is one difference between the rev 7 and rev 9 motherboard that I noticed, many more jumper settings.
