I placed some information regarding the various HP48 rom versions
at wuarchive.wustl.edu and wscotts server at seq.uncwil.edu.
The information consists of a list of the address of each nybble
that differs between versions and its value in each version.
There is also a short list of the areas where these tend to
cluster. Finally, there are a few observation and a describtion
of the file format.
If anyone has access to the HP48S, I would love to know what
rom version it shows. The comparisons cover HP48SX roms A-E,
if you have others, please let me know.
The machine where I have this account will be going away at
the end of the month. My alternate address is:
an973@cleveland.freenet.edu
The account listed with the rom comparison will not be valid
after this month is out.

Contrary to rumor, the case is a tad different from the SX; the port cover is much shorter (just covering the I/O area), and is not removable. (Why did HP go to the expense of designing & making a new case for the 48S, but not go all the way and make it thinner than the SX? The brochure for the 48S should boast "factory air"!) Also, the HP logo in the upper left corner is just printed on, instead of the removable/customizable plate used in the SX. It's obvious that HP plans on other companies buying SX's, putting their own logo plate and software card and keyboard overlay in place, and selling it as their own product. Can't do that with the 48S. For what it's worth, its "R"eset hole is under the righthand foot, unlike my E version SX (SN 3047A00647) whose reset hole is on the traditional left side. Does country of manufacture have anything to do with this? As you can see in my serial number, my SX was made in USA. The 48S I looked at today was made in Singapore. -- Joseph K.
