16K BBC Model B
Now I have restored link S25 so Station 130 is back to being a 32K machine. Using OSBYTE 254 we can read the amount of memory installed. The value in the X register shown by the results of USR is &80, meaning a 32K machine. We can set this value with *FX254, which doesn't accept hexadecimal numbers, so we have to use 64 for the 16K value of &40.
