$27+shipping from AmigaKit which is a bit of a rip off.

$24 plus shipping from Vesalia is better but not by much.

Perhaps softhut might have some and they are in the USA. But their website has not been updated for many years... email them direct first.

Not familiar with this company but Connections has them for $19.28 and they are USA based (but it is not as nice a dongle)

How many BNC connectors are there on the monitor? If there aren't connectors for v-sync and h-sync, it needs sync-on-green input IIRC.

I dont remember exactly, but the back says something about sync on green.  So i think it will work both ways.  There's something like 10 or 20 bnc connectors on the back of the monitor.  That's in addition to a few RCAs, a db-9, and a lot of other connectors i've never seen before.

Erm... EGA was/is digital (6 bit = 64 colors).

P.S. you wont want to use the digital mode... it's only 4-colour
It's 4 bits, so 16 colors (compatible w/ CGA). But you won't want that either. :-P

Possibly, but it's the first time I've heard that. It's pretty easy to build a small adapter though.

Hmm.. Yeah, so what was I thinking of that was analog with the same pinout as 1084S/CM8833-II??

Perhaps there was a 9-pin VGA or something.

There is a software bit in a register

http://www.winnicki.net/amiga/memmap/BPLCON2.html

SOGEN = Sync-on-green

And I think they all have override jumpers/links on the motherboard to enable SOG in all software.

A4000 = J500

It's a JVC. The model number is VM-R190SU.

Here's one on ebay with pictures:

http://cgi.ebay.com/JVC-VM-R190SU-19-BROADCAST-COLOR-MONITOR-BNC-BETACAM_W0QQitemZ170201892835QQihZ007QQcategoryZ21517QQrdZ1QQssPageNameZWD1VQQcmdZViewItemQQ_trksidZp1638Q2em118Q2el1247


I have the manual also.  It's selectable between sync on green and separate sync.  There's a BNC connector on the back for sync signals.  My only concern is that it looks like there's one sync BNC whereas the cable is going to break out H and V into two separate cables.  I found a sort of BNC Y cable mixed in with everything.  Can I just combine them?

Please don't post these long links, they're a pain (use the chain symbol above SIZE instead).

Not sure at all, but probably not - you can build a small circuit for that purpose.

That circuit is already inside the Amiga...

The best solution (assuming the Y-BNC doesnt work) would be to re-wire your 23-pin to 15-pin adapter.  

It would take about 10 seconds with a soldering iron. Even a novice could do it. Desolder HSYNC wire and resolder to the CSYNC pin.

http://pinouts.ru/Video/AmigaVideo_pinout.shtml

They are right next to each other on the 23-pin connector.

Then you'll have RGB+CS on four BNC's

Thanks.  I'll try to hook everything up when the cables get here.
