IBM System/23 problems

Yeah, I'm here in the states, New York to be specific. I would be very
interested in getting ahold of a copy of the ROM chip to replace the
nonfunctional chip on my machine's board, as well as copies of whatever
software I can find. I don't know what software was available for the
System/23, probably mostly just business software, right? What
operating system did it run, or was it just some flavor of BASIC with
disk commands?
