Guys,

I stumbled upon this while searching for parts. It was in an SVGA box, but I can't find any info on it anywhere.

FRU: 15F7932
Part No?: 33F4473

Any help would be appreciated.

Thanks,
Lolo

I think it's over at MCAmafia but there is this beautiful tool you can download and run and it gives you a list of any installed MCA cards, configured or not, by taking their Device ID and comparing to a copy of the list from MCAmafia.

I'd give you a copy of the bootable diskette I made but the forum thinks a 200k file is too big to attach.

Alright, if you want it that way you can have it as a rawrite image. https://dl.dropboxusercontent.com/u/47557993/MCA_IDNT.rar

Now, for you people reading this thread in the future the link above died a week after it was posted because I don't like dozens of little parasitic files leching off the bandwidth a free Dropbox account gives you monthly, so I deleted the file.

If Dropbox doesn't give a damn I don't see why you should!!! It's *their* bandwidth, not yours. :-) What's that attitude all about? Not gettin' any lately? :-) :-)

Much to my surprise I also struck a blank. As I am sure you know the FRU "15F7932" identifies a "field replaceable unit" and there may be several different looking cards that are functionally equivalent. But its not in any of the usual lists, e.g.

http://ps-2.kev009.com/ohlandl/video/Video.htm

however searching on the part number on the chip shows its used on some PS/2 models with video on the Planar (Mother Board board for non-ibmers)

http://ps-2.kev009.com/cgi-bin/sear...DB=default&FMT=query&xDB=default&xFILTERS=--O

will list the relevant pages, one of which is the PS/2 M55SX..
... and looking at the PS/2 55SX it looks like its a boring VGA adaptor....
 
Yeah, judging from the parts on the board (IBM/Epson 15F6864, Inmos G171-35), this is just a plain old VGA.

I don't think I've ever seen a true IBM MCA VGA on a card before. I wonder what this thing's deal was, considering that most PS/2s had the 15F6864 on the planar.

Also, the IBM VGA chips I've seen, either on PS/2 planar or on IBM ISA cards, have a package in the form of a gray ceramic(?) slab. This one has a very different package.

That's a typical type of IBM encapsulation, ceramic substrate with pins, and an aluminum shell to cover it. It started, IIRC, with SLC in the System/360 but was also used for higher pin count parts. Seems to be a quick way for IBM to throw a chip die in a package when working with something new.
 
Hey everyone, thanks for your replies. I downloaded the MCA card ID program, it's pretty cool. I've found myself in a conundrum -- too many spare parts and not enough time to play with them ! i've not yet discovered what this thing is, but my thought process followed the majority of the responses. the fact that i've got an apparently stable system, i haven't wanted to piss her off too much. i found a cornerstone video board MC1608C/11 that i've been meaning to play with as well. i have an NEC LCD3000, i intend on trying out the BNC RGB-HV input with the card.

i've been trying to find a beast video accelerator for the 9595 system i've been building, but there seems to be (is?) a dearth of high color cards left in the wild.
 
If you want beastly video accelerators an IrisVision paired with the XGA-2 card will work and odds are it's the best combination you'll ever get. Remember that we're in the years before high performance PC video cards existed outside of CAD/CAM.
 
i wouldn't even know where to find the microchannel version of the iris vision. that sounds like a tall order to fill ! :)

aside from that, what's a good high color card?
 
XGA could do 16-bit color in 640x480.

There used to be a guy who I think ran the unofficial irisvision page that had spares you could buy but that was years ago.
 
I've got 64K with xga-2, 800x600 in os/2 ... Maybe I'm just psychotic and don't remember what year I'm supposed to be in... I don't know what I'm holding out for.. Lmao

It seems like 256 colors was a big thing ! ������
