On the IIgs, the border color is stored in the LOW-NIBBLE of $C034. When
you set it you should be sure not to disturb the top nibble; do something
like this (assuming native-mode)

LDA $C034
AND #$FFF0
ORA #$000x     <---- x is the color # you want
STA $C034

(8-bit mode)

LDA $C034
AND #$F0
ORA #$0x
STA $C034
