Yeah, I'm here in the states, New York to be

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?
The ROM (ROS in IBM terminology) contained a flavor of BASIC (compatible
with system/34). It was completely self contained (ie it doesn't boot
from the floppies). The CSFs (Customer Support
Functions) which are on
diskette are utilities for managing among other things
diskettes (like
formatting them and copying them) but they were not standalone. They
required/used many functions in the ROMs. They were written in 8085
assembly (as was the BASIC).
