after looking at doing the leds on the switches i was glad the type i got had the opening in the side. one reason was that if the switch goes faulty it's just 2 pins to desolder and replace the switch as led is independent from it ans on the board. just a side note use bright leds. and 3mm not 5mm as they wont fit in the switch.

just a side note to the keyboard.. the stabilizer for space bar goes 180 deg to the others (so the bar is over the top of the switch and not under the switch) as it wont fit otherwise lol

and thank terry.. this one maybe up for sale when finished.. but need it for my case design im doing atm..

ok so the first run of see through MSX1,2,2+ labels.. commercially printed and are scratch / wear resistant so wont rub off easy, also good for the foreign keyboards to make English..

these sell for $2.50 a sheet.

with the mounting to the OMEGA board i found that a 25mm long pin header was just right (i ran out of short headers in the pic and used long and trimmed off the excess)
