Please help!

Just found an old NMS 8220 MSX2 computer. Only problem is someone took it apart and stashed it away. The keyboard, membrame sheets (like the VG8020 sheets - picture) and some loose springs are not assembled.

Question: in which order do I reassemble the sheets? Which must be above, middle and below? And where do I put the springs?

Thanks, that solves the membrane sheets problem. The springs go under the spacebar?

The connectors are placed under the spacebar.

I know where the connectors go. But there are 5 springs left (sprungfeder). Where to place them?

Yes. The image could be missunterstood.
The upper springs belong to the STP/SELECT/F5/F4 keys.
I paced them seperately to hihlight the orientation of the springs. There is only one spring holded by the springbar.

Thanks again Hamlet. Found this 8220, a guy wanted to trash it. Luckily he was okay with me taking it. Smile

The 8220 works fine. Too bad I have only 5 springs for it. I put them under space,cursor keys and F1. All other keys don't work. Only those with springs. So I need lots of springs. Crying

One other thing that must be fixed are the capslock and power lights. Loooks like somebody ripped the wire off. Where do the colors belong (yelow, white and red)? I can solder them on myself.

The 8220 as I found it:

Where do I solder these?

Assembled it look very nice. :D

You could try with RepairBas (Bas Kornalijnlijper), he got me some springs in the past.

4 yellow
3 white
2 kind of red
The keyboard is exact the same which build in the 8020 (I swapped them several times w/out problems), maybe you can get a cheap and common 8020 you can use for spare parts.
I like the 8220 very much, it´s a compact MSX2 and the colour design is IMHO much better than the 8020 (except Orion70 ones).

Fixed it! Had to put a spring under the CapsLock key to test the LED. Smile

Now to get those springs.
