Problem found

the PINSEL0 register GPIO0.14 bitpair for the LPC2101,2,3 should be set to

01 where for the LPC2104,5,6 it should be 10 !!!!!!

So MCB2103 users beware !

2 leds on the MCB2103 connected to GPIO 0.17 and 0.18 wont work unless you connect 2 pullup resitors on these outputs . (both outputs are OPEN DRAIN !!)
