IBM System/23 problems

My IBM System/23 doesn't work properly. When turned on, it displays a
series of numbers on the screen, and stops at "FD". Of the numbers
printed, "0B" is inverted and flashing. I found a listing of the error
codes in google's cache of (part of the archive seems to
be down).
mail-archive/classiccmp/1997-07/0566.html+IBM+System/ According to this,
the error code "0B" indicates that one of the ROM chips on the logic
board has failed. I looked at it, and it is soldered to the board.
Desoldering and replacing it with a socket shouldn't be a problem, but
I will need to find another ROM chip. Does anyone have a spare chip, or
the ability to copy a good chip? Also, once I get this machine working
again, I will need to find some software for it. I would assume that
there is no place to download System/23 software, or even a way to get
files to usable 8 inch floppies. I have a few disks given to me with
the computer that may be bootable, but I don't know. I don't really
know a lot about the System/23 other than the fact that it's really
heavy. Any information would be appreciated. Thanks!
