Does anyone have a checksum for the PDP-11/53 ROMs?
I'm converting
an M7554-SD. The ROMs from M7554-04, I think, are the ones I need.
According to Jonathan Engdahl's page, they are 261E5.hex and 262E5.hex.
You can try the straight .BIN files instead of .HEX files.

Let us know how your conversion goes. What are you doing to convert
the s-box hardware? I have a M7554-SD and need to do the same some
day.
