Fairlight-CMI

Greetings, all -

I just bought a IIx and it's now having a problem booting. It was working fine, and then I pulled some of the cards to check thier conditions and to check the battery, and now it will not load from either floppy drive. 

It does boot up from the ROM, and it get to where it shows this on the display -


* READY *
:


When it gets to this point, I assume it's supposed to load from the floppy disks, but it doesn't. 

The video works, the alphanumeric keyboard works, and the keypad on the keyboard works...

What should I check next?
THanks -
