Try on it for whether you like the feeling of it(it should be very stiff to type). Sell it and get a newer model you like may be a better choice.

Retro things should be sell to those who like retro things at a high price.

BTW, if you really want to keep it then i think LYP will sell the adapter.

Problem is the switches on the keyboard are blacks. Also i wouldn't know how to replace the switch if i could get reds.

Modding them to ghetto red seems doable for my skill.

Your IBM Model M is a buckling spring. It's not nkro so it may do between 2-4KRO. Unless your going to be playing beatmania or o2jam it's not gonna matter. Ibm buckling spring keyboards are rather loud. Some people like them for typing.

You can get more information for the AT to PS2 adapters over at geekhack.

USB to PS2 adapter
http://geekhack.org/showwiki.php?title=PS2-to-USB+adapters
For my vintage keyboard i'm using
5 PIN DIN (M) to 6 pin PS/2 (F)
http://www.amazon.co.uk/Belkin-Pro-Reverse...&sr=8-1-catcorr
With either a
NEWLink USB PS/2 Keyboard Adapter (N01210)
http://www.amazon.co.uk/NEWLink-USB-Keyboa...0/dp/B001GXR72E

and

6 inch Fully Rated USB Extension Cable A-A
http://www.amazon.co.uk/inch-Fully-Rated-E...95895364&sr=8-1
Or
Belkin USB PS/2 Adapter
http://www.amazon.co.uk/Belkin-USB-PS-2-Ad...95725083&sr=1-2
AT and PS2 share the same protocol by the way

You mean you cant find thing like this in Malaysia?

I think LYP will have it . Besides, i have seen it at my hometown(nameless small town) and may be ''Challenger'' too?

BTW, I think we really cant find any blue cube in Malaysia. The only choice that is quite widely available is this.(LYP lots!!!)

if the ps2 to usb adapter isn't either the blue cube or belkin, then i wouldn't recommend it.

There is no knowing if it would work well with old keyboards unless you've done research on it.
@thomadyeoh

If you do find the din5 to ps2 please let me know as well 

Which floor? Going this Friday...

Thx for the info 
Got any pictures ?
Do they have the din5 female to din6 PS/2 male with a metal encasing ??? The plastic encasing is fine, just wondered if they did though. Performance wise i think this one all perform the same. It's only when it comes to PS2 to USB adapter that they all don't perform the same especially when it comes to old vintage keyboards that have a high energy requirement.
