With the availability of the service manual and ROM images, I thought I 
would try to make a parts list for the 8296 (see below). There were a 
number of problems, so it probably needs correcting.

4K editor ROMs have a description at $E800-E900, so these are easily
identifiable. This area is not accessible from inside the 8296.

"324242-01" is the same as "324242-10". The service manual says "-01",
"-10" is questionable for a system with only a few variations.

There are two versions of "324243-02B" that are very different. One is a 2K
ASCII ROM. The other is a 4K EURO ROM. The 2K ROM agrees with the description
in the service manual.

"324243-04.bin 2017-05-23 4096" is the same as
"324243-04_editor_din_ue8_8296d.rom 2011-05-22 4096".

"324381.01B" is the same as "324402.01".
