The .MEM files are identical in format to the files produced by J-F Garnier's ROM dump program which can be found in the Emu71/Win manual and J-F's Emu71/DOS manual. These files conform to the TEXT Data File format described on p.247 of the 71 Owner's Manual which is why the READ command can be used.

To convert binary ROM images to the MEM format the ROM2DMP program in Christoph's FILETOOL package can be used which is how I converted the Diag ROM image. The line numbers will need to be stripped off.

Given that, the easiest way to load ROM's into the 71B is to ROMCOPY the binary images from a LIF disc or image. The HC ROM's will need to be loaded by Paul's program. Speed is also a factor. To load an ASCII image takes about 17 minutes for a 32k ROM or about 45 seconds to load the binary image using ROMCOPY.

Thanks to Paul for these excellent programs. The one for listing the memory buffers is especially useful.
