I've noticed that some Williams DMD games call out a 3/8 amp fast-blow fuse for the dot matrix controller board, fuses F601 and F602 (World Cup Soccer, for example), while others call out a slow-blow (like Getaway). Is this a mistake in the manual? Or did Williams at some point change the specification?

I'm also guessing that a lot of games that specify a fast-blow fuse have slow-blow fuses installed, just because they seem more common. How much of a risk is using a slow-blow fuse to the DMD?

Thanks in advance!

Just as an update, this evening I've been told by somebody "in the business" that these fuses should in fact be slow-blow, and that the manuals specifying fast-blow were published with this error (along with others).
