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...

#Datatrak teaser: a sales leaflet from the early days. You can tell it's early because it shows Securicor and Wimpey/Wimpol's involvement. Later on Wimpey stepped back and handed the reins to Securicor.

The Locator in the photo is the Mk1, the original 68008 based unit.

edit: I love the little photo of the #DEC hardware - an RA81 hard drive and something else on top of it.

"How would you like a pile of #Datatrak stuff? I found it in our store cupboard and saw your website on Google when I tried to find out about it."

It's going to take ages to dig through these boxes of old hardware.

I've just uploaded the #Datatrak Locator Mk2 reverse-engineered schematic to Github - https://github.com/philpem/datatrak-locator-mk2
This is a long-running project (started in around 2019) and I'm glad to finally have this part finished!

The #Datatrak Locator Mk2 schematic is coming along nicely. Finished the 68K and 8031 CPU schematics and I/O, which just leaves the LF radio input to enter into KiCad.
