Now, this is slightly more interesting. I guessed based on the appearance that this board is a generic XT clone like the TURBO XT on this page: http://www.minuszerodegrees.net/xt_clone_bios/xt_clone_bios.htm
After dumping the BIOS, a cursory, superficial look at the ROM from the one on that page and the ROM I just dumped tells me this company may have just hex edited their company name into the display text at the beginning of the ROM itself
@derek I'm pretty sure Leading Edge was a sponsor for The Computer Chronicles, which gives them points in my book. I seem to remember the clones featured on their title card as being relatively attractive machines a well.
The IBM gave the most trouble, but unlike some of the noname clone stuff of the era, IBM's technical manuals effectively describe how to build their computer, from detailed system board schematics, to the full BIOS assembly sources. If that's not enough, http://www.minuszerodegrees.net/ has every troubleshooting detail documented already. I cut off two tantalum caps on the 12V power rails and that fixed the short to ground and brought this thing back from the dead
