How to: install 3.1 roms

[BlitzThose]

how do you install 3.1 roms into a1200 ive taken the old ones out but it looks like the pins are to wide to fit also a link to a tutorial would be nice

Hum,
1. Place the A1200 unit upside down on a flat surface.
2. Use a screwdriver to remove the five case screws.
3. Turn the unit to normal, face front position.  Do carefully flip backwards the top cover
and then the keyboard assembly.
IMPORTANT: Take care not to damage the cables to the top cover or the ribbon cables to the
keyboard assembly.
4. The main printed circuit board - protected by a shield - is now in full view.  The
operating system ROM ICs are labelled and located at position U6A (under) and U6B (upper),
just at the blank of the shield.  The old ROM chips should be marked: @1992 V3.0 39.106
5. Note the orientation of the old operating system ROMs, and then remove them from the socket.
IMPORTANT: You should be aware of the fact that there are spare pins at the sockets.  You
have to align the ROM ICs to the right side of the sockets so that there are spare pins at
the left of the ROM ICs.
6. Align the 3.1 ROMs with socket U6A and U6B, and press firmly into place.  Be cautious
not to bend pins.
7. Installation is now complete.

Good luck...

The new ROMs should push right into place where the old ones were.  Of course you have to make sure they are in the right sockets, are facing the right way, be careful not to bend the pins, take static precautions, etc....  

If the pins are too wide you may have gotten the wrong ones, like for the wrong machine.

Good luck!  You're halfway there.

Nope, the chips are the same width for all amigas.
It`s most likely that the pins are just spread out wider at the bottom  
All he needs to do is *carefully*  lay each rom down on each side, and push the bottom of the pins back to being square, and then they`ll fit.

the pins just needed to be pushed further in on a flat surface, installed and working now.

just gotta wait for my apollo accelerator, 1.6gb 2.5" hdd, and 32x extenal cd rom to arrive in the post and its 3.9 time  :-D

Just an afterthought. The legs of the rom chips are always too wide to fit in the sockets. Here's the trick: lign up one row of legs with the sockets nearest to you and just rest them in them. Second, apply pressure with your fingers so that the row of legs that are just resting in the sockets will flex a little. This gives you room to insert the second row of legs. Tilt the second row of legs in their sockets. Apply downward pressure to secure the rom firmly in the socket. Done.
