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 [url=http://hp.giesselink.com/Emu71

When I look at the MEM files, that came with the package of ROM images made available here recently, with a HEX editor on my PC I see that they are strings of 64 ASCII characters followed by 0x0d (CR) 0x0A (LF), when I create a TEXT file on a 71B, such as using transform to convert a BASIC program to TEXT the file it creates has variable length records each one starting with a byte of 00 followed by a 1 byte length and no CR LF at the end of a record. If you take the DOS text format file and copy it over without transforming it to LIF1 format, even if you get the correct file type set in the LIF directory, the READ command on the 71B is going to have a hard time understanding the file.
