In his response to the original post Dave Swingle referred to a modification that had been published in an old D World. The article was published in the Winter -87 issue and the first paragraph reads: " The operation of the exsisting lamp delay module (LDM) is unpredictable at best. This is due to the design of the device, which uses power stored within the module while the doors are closed and the lamps are off to sustain the module through a subsequent delay. If the doors are open for 30 seconds or so the power stored is depleted to the pointwhere upon closing the doors the lamp delay will be significantly shorter or may not function at all. There isn't a reliable way to increase the time delay using the present module." The article was written by Marc Gladstone and he went on to describe a rather complex but complete modification, including a parts list and wiring diagram. At the end of the article, Marc indicated that he would be willing to build some modules if there was enough interest. (I have not yet had time to read through my stack of old D World magazines to find out if he in fact did "go into production".) Unfortunately my scanner is on the blink, but if anybody is interested send me an e-mail and I'll send a copy of the article. Roger [Non-text portions of this message have been removed]
