Serial numbers shouldn't lie but they sometimes do.

I have a pair with both sets of serial numbers (one on the back the other on the port) beginning with a 1.

However they are upgraded Mk1s. I know this as I have managed to flash the latest firmware, and also have sent a 24/96 signal to it which worked.

Serials beginning with a 2 or a 3 would definitely be 24/96 from the factory.

The firmware is the best guide. I believe that the 24/96 had revision 4 and upwards. 18 bit could not have this version.
