ISA Cards from my 386sx system

"SomeGuy" gave me some fantastic information on the ISA floppy controller that I have so I have decided to post pictures of the ISA cards in my system.

Any information you can share to educate me would be great!


Denon? SCSI controller I can't find any information about this card. To me it looks to be the oldest card?





I know this one because it lists when it boots up!

Cirrus Eagle II video
I am not sure of the video ram, it says at least 256KB when I run the diagnostics. Would this have been a high end card at the time? I did notice the port on the top of the card and found some details on WIKI but now I have already forgotton what that port is called (Edit, VGA Feature connector! that's the one)





I'm embarrassed to say I don't know what this card does at all!






And the floppy controller

The two large chips on the unkown card are LG GM16C450 "ASYNCHRONOUS COMMUNICATIONS ELEMENT" and point to UARTs, leading me to believe it's for serial. The connector looks like a DB-25.

That SCSI card looks kind of bare-bones and low-end, it doesn't have a BIOS chip, so that means it can only be used when a driver is installed.

That VGA card would not have been high-end, but what is interesting is that second (video?) plug. Some of these very early VGA cards had a second plug for running an EGA or CGA monitor. If that is what it is - that sort of flexibility is desirable to some vintage enthusiasts.

That card that you don't know what it is, is some kind of serial card. It has a pair of 16450 UARTs, and one serial header on the backplate. That might be a header for a second port on the top of the card, but that doesn't quite look standard. It could be something special-purpose, but I doubt that.

Very interesting finds!
