Thanks for the offer Woody may take you up on it if I can't cobble something together soon.
I've got hold of the software now, and I've begun playing with the interface cables I already have. I've tried a USB to serial cable (forgot about the scooter needing TTL levels), and an Alinco ERW-8 cable (its a FTDI chip which does USB to serial and has TX/RX already joined). The software was happy with both of these, but I get nothing back from the scooter in the software. The ERW-8 cable has traffic LEDs and shows a slow TX/RX happening, but it looks like just a byte each time.
I've wired up a Neutrik plug with pin 2 for gnd and pin 3 for data, and when its connected to the ERW-8 cable. When the scooter is switched on, I get speed flash on the scooter LED indicator (faster than low battery, but slower than fault), and it wont operate. When I disconnect the cable from the computer and restart the scooter, the scooter LED comes on as steady.
I've still got a another interface cable to try, and I've got a MAX-232 board somewhere. I've tried running the software with Windows XP SP2 and Windows 7 (normal and XP SP3 compatability mode). Pretty sure I've also go a laptop with Win XP on it, with a serial port stuck in a bag in the garage as well, so plenty of options still to try.
When I get a moment, I'll share a little of what I've already done to the scooter to improve / maintain it.
Cheers for now.
