You got a few of them riled up with that SCO UNix replacement system. :-)

First we need to know what file types Mike is using.
The proposed solution is OK for binary images, but actually in EPROM
burning it is more common to have HEX files, which have lines containing
an address, a number of bytes, and usually a checksum, all in ASCII HEX.
 
To combine those files, you would just need to cat them together.

If the OP is using osX I could recommend a little program I use quite a
bit - burning EPROMs many times a week - called Synalyze It! Pro. Easy
to merge files, do checksums of various levels of complexity and compare
binaries.
 
Here is the free version:

And I do recommend buying the Pro. I know I don't use all the features...

As per code NEC 250-23(b), 250-24(b). The building's grounded electrode must connect to the main ground wire which connects to main neutral wire which connects to the the back of the panel.
