I cannot open the page.
But i am willing to mod for you.

I have 2 1MB 30-pin SIMM modules with IBM label, not sure of the part numbers. Will post pics later.

here is a copy of the mod:

According to the webpage, 3-chip simms don't work properly with the mod in motherboards.

Here you go

I asked a friend of mine who gave me these, he said he "borrowed" them from some IBM-branded 286 at work a long time ago.

I will have a look and see if I have this specific RAM laying around. Will report in this thread later. I don't have any IBM's anyway 😀

@ racoonRider Sadly I think those simms are "industry standard" and going by the part numbers, they came out of a 486SX-25. You can double-check with a simple volt meter. Pin 22 is a ground pin. If this is a special simm, pins 24 and 26 should also connect directly to ground. zero-ohms.

I had a look in my little boxes of 30p memory, but I'm sorry to tell I don't have any of the RAM strips you are looking for 🙁

I've been alerted on another forum that this expansion board: http://www.ebay.com/itm/191019336764 Has the memory type required for my system. While I believe it to be a bit overpriced if it 256k simms, I would gain 3mb? of ram. Not exactly how I wanted to occupy one of two expansion slots, but thems the breaks. Also for the record, this board is required for memory beyond 4mb anyway. So there's that.

So if you have some weird sugar-cube memory at home. Even if its not the part numbers I listed, I'm interested.

I am having tons of ram soon from ebay, will have to look if there is something usable in there.

protip: They wont work in any machine but the model 30-286 and related items. thanks for remembering me!
