Perfect! Can you post some pics showing all the bits connected up before you install everything in place? I'm curious to see how it all hangs togerther.

Nice one, and you didn't even need to remove the OEM micro-switches to extend them!!

PS, pic of the back of the new micro-switch board too please?

can't find a suitable plug for the internal VGA OUT connector on the board, so am considering just using the DB15HD connector internally... not really what I wanted to do...

It would give you the same placement flexibility imo - why dont you make 2, one for Miggies using a DB9 (CGA RGB Style) and a second VGA pass thru direct to the VGA input on the GBS?

Used strip-board, as the switches have a common ground, so made things easier...

I bought a second GBS(8220) so I'm not worried if this is a permanent installation in the LCD base that can't be used for anything else.

Nice work, very neat!

PS, is the common ground the red wire/strip?

can't use the DB15HD connector internally, there's not enough clearance between the connector and the case...

good point, can always desolder the connector from the GBS and wire in one direct to the GBS board.

Btw, what do you have the yellow connected to? (or is it not connected, just terminated with heat shrink?)

Its yellow instead of grey, I swapped the wire in the loom a while ago when I was trying the separate H and V sync signals..

Found some plugs with 2mm pitch, not the right plugs, and I had to modify two plugs for the one socket...

Made up the loom to connect from the GBS to the VGA input on the monitor... and on to the pics...















Switches need "fine tuning" as they're held in place by a piece of foam wedged between the PSU and switches, which means if they're off centre, or not straight, buttons accidentally get pressed
