Macintosh LC III repair help!

[JRL]

Would somebody happen to have the LC III motherboard layout? My LC III was shipped to me without the ROMs installed and I need to know the correct position of the ROMs so hopefully I can check if it's working.

Thanks!

I don't have any pics, so I'll try to be as descriptive as possible.

Looking at the back ports with the lid off, the "Hi" ROM (341-0662) should be in the slot right below the battery holder, with the text reading right-side-up, or readable when looking from the back of the machine. NOTE that there is an extra set of pins on each ROM holder...make sure the ROM is as close to the PDS slot as possible, leaving 2 unused pins on the opposite side of the holder.

The same goes for the "Lo" ROM, (341-0661)

Hopefully this makes sense.

That was just what I was looking for! Thanks!
