It'd be nice to know what chips correspond to
what portions of the ROS
tests
The Maintenance Information Manual has enough information to identify
the failing module. I don't think there's much point to identifying
it to the chip rather than just the failing module, since it's
basically implausible to repair the modules. The simplest repair is to build a replacement module
using a modern
flash memory chip and a CPLD. That's how I plan to fix my 5100 if I
can get a dump from a good machine. I've also considered building RAM
modules suitable for replacement or expansion.
