Stupid. Me either. > Since P[7:0] are high-impedance when the chip is in 8-bit mode, I will buy > some thin wire tomorrow and use it to connect P15->P7 ...

Since routing of P[7:0] is went through L3 inside pcb, so I suggest no need to cut traces on P[7:0] or directly soldering. That's a little kind of hard. Take apart the one on pcb first then diretly use a new U21, "raise up" those pins P[7:0] and P[15:8] on IC body first. Then hand soldering the new one on the pcb and use wires to solder. > I am still listing PCB errors and possible improvements here: > http://www.milkymist.org/wiki/index.php?title=RC1_errata Each item of them is reasonable and good for next version, I'll watch this.
