#Bridgeboard install help
2 messages in this thread
Don,
I'll check that. One thing that I did notice was that jumper J1 was not
jumpered as illustrated in appendix H of the Bridgeboard user's guide. The
jumpers are as follows:
1 2
3——4
5——6 as opposed to:
1 2
3 4
| |
5 6 as described. Any thoughts on that? By the way, I really
appreciate your help. It's nice to know there are other users out there who
are willing to offer advice to lost soles like myself. I hope I can return the
favor someday. Bob Rokosky also mentioned I might check out all of the chips
on the board–he also indicated he had seen a similar problem. Should jumper
J7 be unjumpered?
Thanks again, Mike
P.S. I'm so impressed with the Amiga that I don't know how much I'll use the
bridge when I have it up 🙂
Mike,
You bet that will make a difference! The jumpers on the default video
mode select (j1) should be as illustrated in the book!!!! Also, there should
be NO jumper on J7. J7 is a production test jumper and having a jumper across
it could very easily cause you problems. (Actualy, if memory serves me
correctly…J7 is a set of pins, not a dual pair)
