I'm using an old Aydin Controls rgb monitor on my Amiga, and I had a similar problem when I tried to hook it up. There are NO DB23 connnectors on the market. According to the guy at You-Do-It Electronics, Commodore may pull the stunt that IBM used when they introduced their monitor, which was to get an exclusive license from AMP (#1 big connector company) so that only IBM could buy those connectors, and thus you could only get 'em from Big Blue. Hopefully Commodore won't do this. But in the meantime, how do you get into that connector on the back of the Amiga? I did it by taking a standard female DB-25 and hacksawing off the end. Then I connected the 3 video lines plus sync to that, and put BNC's on the other end. This works fine. One hint is not to hacksaw the ENTIRE connector through, just the part that goes into the connector on the Amiga. This will make the connection much more stable. I now think that if I'd mounted the 'DB23' that I made to a wirewrap board and wired it to 4 BNC's (on the same WW board) and then just used standard BNC cables from there to the monitor it would have been a little more robust physically. Oh - don't forget that when you hack off the end of the DB25, the pin numbering changes on the bottom (hi-numbered) half. I forgot this and grounded the Video Clock Out from the Amiga. The monitor blitzed out, but no damage was done. I fixed the connector and I was back in business. Good job Amiga!
