So, my Athlon rig had no I/O shield, and I decided to do something about it. Figured there are a lot of those missing out there, so thought it might be a good idea to snap a few photos and write something quick up about it, hoping it'll help/inspire others in the same situation.

The two-part I/O shield that gave me the idea. Figured it would be easy enough to just replace the middle part with one of my own making, keeping only the fastening edges.

Drilled out the rivets keeping the shield together, and cut a blank piece of .5 mm sheet metal to the same size as the old one. Used galvanized steel because that was what I had at hand. Aluminum, plastic, etc is of course easier to work with.

Cut away everything but the frame from the other part of the shield, using a regular pair of scissors. Snapped a pic of the Athlon rig's back side, corrected the perspective error in Photoshop, and printed it in 1:1 scale, to use as a punching template. Punched the centre of the round connector holes and some other strategic places, and used the old I/O shield as a template to trace the holes for the D-subs. Drilled and filed out the holes, and completely forgot to take any pics during that. Protip: a step drill bit is extremely useful when working with thin sheet metal.

Glued together the sheet and the frame with cyanoacrylate glue, and cleaned some rough edges up a bit with a piece of emery cloth.

Installed in the computer. Doesn't look too shabby if I might say so myself, and probably by sheer luck, it fit right away without any further modifications 😀

I'm amazed someone hasn't begun producing blank ATX I/O plates. They would be useful not just for boards where the original is missing, but also all those AT/ATX Socket 7 boards that would be so much happier in a nice ATX case.

Hmmmm... Phil mentioned blanks in his 386 or 486 retro build on youtube.
He stated that you can buy blanks. Though I can not find anything on eBay.
I think that blanks are to be found in local shops or something like that.

Nicely done. I don't work with metal, so i'd probably just cut out a piece of silver duct tape and cut the holes out with an exacto knife. 🤣.

3D printing would be useful there, printing that would be fast and cheap because such shield is thin and flat, and there are big holes so you don't have to use too much material 😉

I was just thinking the same thing. Would a cheap plastic IO shield cause any problems with grounding?

Now for some blitting from the back buffer.

nice work!

but call me jaded, but wouldn't it be cheaper to get one on ebay? That one you made looks VERY generic and probably cheap.

yea $5 shipped: http://www.ebay.com/itm/162042305656

It is a mistake to think you can solve any major problems just with potatoes.

They do exist, and they're available on Ebay and not cheap.

I've considered attempting to create my own shield before now but have somehow not needed to yet.

The problem with the AT I/O Shields you can get is that they lack the punch-outs for serial and such. There used to be some in the 1990s, and I have one, where there were holes for Serial, Parallel and other stuff, the problem being that the ones I have seen all screw into the case they came with and won't fit on normal cases. Part of me thinks it wouldn't be too hard to just cut the shapes out of a sheet and using smaller plates of metal, bolt it into the case neatly. Sheet metal tends to cost more than I would like though.

Seen those blanks too, however, they're made in very thin sheet metal, that's gonna be hard to work with. You'd have to punch the holes, no way you could do a neat looking job of that using the kind of tools you got at home.

Lol, had no idea there were such a thing as a generic I/O plate, thought there were no "standard" port configurations. Never occurred to me to check ebay, thought it would be completely hopeless to find something fitting...

Oh well, too late now. Might pick up one at some point though 😀

I love those... $30 to ship a bloody 10g object. You could send this as a normal airmail letter and pay $3 or less.

I'd guess it's an ugly tactic to get a good ranking when potential customers sort search results on price. List something at $5, add $30 shipping, send it as an airmail letter at $3, end up with $32 in your pocket.

I've seen this bullshit tactic all to often, the other trick is akin to domain squatting. A seller does not have something in stock, but expects to at some point so they list the item anyway with either a price or a shipping cost nobody will pay, say, a bag of drive screws for $9999.99 shipping. So far as I am aware, the latter at least is against eBay's policies and can be reported. The first measure is just a scumbag's way of trading and you can do nothing about it. If they're so worried about prices, they can set a reserve I am sure.

I harassed one of these people once, they got rather mad. It was fun.
