The Asst. Curator of the Signals Museum at RAF Henlow, Alf Fisher, is trying to obtain schematics for the above machine , He says, "I have a Creed manual which covers everything mechanical but only block diagrams about the electronics aspects of the machine. I suppose they had a policy to replace a printed circuit board if it became faulty rather than diagnose a fault and repair it. Please can you help at all with the electronics of the machine? " Anybody have any info ? Cheers , Geoff. -- No virus found in this outgoing message. Checked by AVG Anti-Virus. Version: 7.0.344 / Virus Database: 267.11.3/107 - Release Date: 20/09/05
