Narrative:
I cleared an SF34 to cross runway 26L at L-6. While doing a new ATIS; and amending a flight plan; a B737 called ready for takeoff runway 26L. I cleared the B737 for takeoff; but did not realize the SF34 had not yet crossed runway 26L. The asde-X alerted; I canceled the B737's take off clearance; but he elected to takeoff.
