If this is the last line in the log, then your rom image is
probably broken. It should have a size of 4194304 bytes.
My ROM has the following md5sum:

2623a0c438045ea04d2cc67310c97743  /home/BK/libmol/rom/rom.8500

Note that the MOL rom-grabber application does not work
that well with recent MacOS versions. Boot the 8500
with extensions and virtual memory off before running
the application... Also, make sure the image is not
encoded in any way.

If you star MOL in debugger mode (startmol -d --oldworld), then
the first assembly instructions should be

	fff00100 b       0xfff00108
	func_fff00104:
	fff00104 b       0xfff00154
	fff00108 mtsprg  1,r1
	fff0010c mfcr    r1
	...
