The LM/Viking LX Repeater (relabeled Securicor) I have has IC20 missing as well, but does have IC21- the clock module, and IC13 the EPROM. It was supposedly operational when it was pulled from service, so I don't believe you'll need IC20. I don't have any way to read them, but if you want, I'll pull and send them to you as long as I get them back. Kevin
