Been given a box of spare ROMs, allegedly found in a pile of #Datatrak gear that turned up on ebay some time ago.
After matching up the images, I found what appears to be LFTX v8.1.1.8 - the LF transmitter software.

Sadly it doesn't boot in the Locator emulator. Digging further, the rackmount hardware was a Force Computers 68000 VME-Bus system, and the unknown writes are to mystery VME cards.
Wish I knew the first thing about #VMEbus...
