Hi i 'm wondering if you could help me out here - i'd recently bought an X-Mem, PlayCity and Mini-Booster boards from a seller on Ebay and connnected it to a Mother X4 board. However when i'd connected the X-Mem and Mini-Booster boards to my CPC 6128 and connected the USB cable from the Mini-Booster to my PC to transfer a file the CPC crashed and displays an artifact screen (blank multicoloured) and keeps showing this screen every time i boot the CPC. I think its because the red wire was connected on the Mini-Booster board which you shouldn't do as stated on the manual. Do you know why it shows this and what i can do about it? Please could you help me out on this???
milkyway galaxy,
If you connect the min-booster as stated in the manual, does the CPC boot up as expected and the board work as documented?
If this is the case then there is no need to understand why. I could only assume that the red wire may be power related which may cause the CPC to go into an unstable mode.

Try this :-
Just plug in the Mother X4 Board ONLY and Power up.
If that works then Add the X-Mem ONLY
If that works Then add the rest one by one WITHOUT the USB Cable from the PC
Good Luck

I would advise cleaning the contacts on the expansion port first, use an eraser to rub the contacts clean on both sides OR you could clean them with a bit of spit and a tissue as long as you dry it well.
Once it's clean connect the bits as rpalmer has said.
On the X-MEM there are some switches. Make sure one of the switches is set to 6128.
You can stop the X-MEM booting firmware and basic (there is a boot switch for that) or last resort you can disable the rom part of the xmem entirely. There is a link connector under the large chip near the connector. Disconnect that and it prevents the rom being active.
If that makes it work then it's possible the data in the X_MEM needs re-programming.
It may just be that it's reading a bit of garbage data and not starting up, or it could be a dirty connection.

I'd already tried to boot up CPC without even adding the Mother X4 board or any other expansion but it still displays the multi-colour screens. This should indicate that the board is damaged so do you know which board chips should be replaced?
@Milkywaygalaxy
I would like to see some photo's of the Screen
Thanks Ray
