etumor, do you happen to remember what part you got for the scoreboard power? It would be nice to have a record of it if possible for other users (myself included... hehe)
taunt, if you get the repro scoreboard, it has an additional "daphne" connector so you don't need a special cable. A regular PC parallel cable will work fine. If you have an original scoreboard, you will need to make a custom cable as described in the daphne docs.
I also have a daphne cabinet, and have set a few up for others as well. I usually use TVs for the monitor. That way it's an easy switch to go between a real LDP and a PC with TV-Out. However, if an LDP is something you know you'll never use, a Happ monitor may be your best bet, although a bit more expensive. Hans Eilers' great monitor/TV swap tutorial just went online at the DLP.
