Title: Stupid question: Kickstart roms...
Post by: KAi on May 18, 2008, 08:24:38 PM
Hypothetically speaking, what would happen if *someone* inserted the Kickstart Roms of his Amiga the wrong way round (i.e. pin 1 at the wrong end)? Would it be a bad sign if they got very hot and started to smoke?

I know that nobody in his right mind would ever do such a thing, but if it happened, would this Amiga be dead?

I would think at the very least the Kickstart roms would probably be destroyed. Since the components on the motherboard aren't designed to be protected from this there would quite possibly be other component damage as well.

I suppose you could be really luck though:-(

Probably the ROMs are destroyed in seconds - it has been done and reported.

On the same topic... I just ordered a set of A1200 Kickstart 3.1 ROMS from Amigakit....

How can I tell which one goes on the top and which one on the bottom?

I am looking at this picture here:

391773-01 is put into socket U6A
391774-01 is put into socket U6B

That is what my installation instructions for A1200 said. But your chips has different numbers  :-?

I bought mine at www.vesalia.de

This is confusing, maybe someone can shed a light?

EDIT: It will come with instructions, so no problems there.

I'd guess the higher-numbered ones would go in the same way round though.  I'd also guess that putting them in the wrong sockets wouldn't do any damage, it would just mean your Amiga would start off running the wrong bit of ROM and not boot up.  But don't quote me on that.

The first pin is identified by a black indentation or dot on left side of the chip.  Also, make sure to leave the empty holes in the correct side of the A1200 Kickstart sockets since the A1200 was designed to take as much as 4 megibytes of address space for future expansion that never came out.

@everblue

I think the roms pictured are for a 4000T and probably won't work in a 1200. Of course the picture you have might just be for ref. just don't want you to run into problems.
