Amiga 25 pin Video out
« on: March 05, 2009, 08:36:20 AM »
Hello Fellow Amigans.

I have a hardware question about a A500 with a 25 pin Video out, though i never heard of a 25 pin out, i was wondering, if any of U ever heard of it ??

Kindly regards SDH, Denmark, member of www.amiga.dk

Never heard of such a thing before. Do you have an RF modulator that fits it?

The 23 pin video/RGB port is commonly mistaken to be 25 pins.

I saw your post on Amiga.dk, and as PaSha states, it's a 23 pin connector, not 25 pin.

I guess your next question would be something in the lines of "how do I connect it to a monitor", and to save you the efforts, I'll say "you can't" and explain that the modern monitors don't sync down to 15kHz, so you'll have to use a TV and suggest the scart adapter at the local dealer.

@skurk

I guess you haven't looked at the picture at amiga.dk then. The computer in question actually has a female 25 pins connector instead of the normal male 23 pins connector.

No doubt that it's a modification made by one of the previous owners.

Wow! My guess is the original connector was damaged and the owner found it impossible to find a replacement, and so subbed in a 25-pin instead. It certainly isn't standard! If you open the case you might find that 2 pins at one end have just been left out.

Too bad male/female got reversed, otherwise you could've just plugged in the standard 23 pin connector (correctly oriented!).

This is very much what I'd guess as well. I've seen lots of weird Amiga hardware (in person or in pictures) and I've never seen a 25 pin video connector on one. Open it and look inside for signs of it being a later modification (2 unused pins on one of the sides, signs of the plastic case being cut to widen it, etc). If somehow it really is an original 25 pin video connector, you're on your own figuring out how it works haha.
