Hi everyone

I am building (very enjoyably!) the PC-Retro kit that reproduces the original IBM PC motherboard. I would really like a CGA graphics card to go in it. Ideally the huge original IBM kind but I will consider others - I don't know this subject very well. I know there are some VGA cards that would also work and be easier to plug into a modern monitor, but original-style CGA would be my first choice. I can see some on eBay US but thought I'd ask here first. I am in London, UK so would prefer one in the UK if possible.

Let me know if you're interested in selling one of these to me.

Thanks very much!
 
I've got this one:

This looks more like an ISA Ethernet card. If the DB connector has locking posts on either side, it's AUI Ethernet. Datamedia corp is registered as owning a range of MAC addresses. Check the back for a MAC address sticker.
Since I use it with a CGA monitor I'm quite certain that it's a CGA card! :)

And the coax connector is composite video like you're used to with the RCA connector on CGA cards. It works normally on a TV.
 
OK, sorry. I've never seen a CGA card with a BNC connector. Yes, the 6845 should have been a dead giveaway. From this angle, it sure looks like the ISA ethernet cards I have. Here's one with an obvious 3COM plastered all over it, but at first glance, it sure looks similar.
