Hi all,
I know that this is a long shot...hoping to locate an MKS 5000 that is available - maybe after someone has done as MKS 6000 upgrade..more details here at the Wanted ad.
It might be long shot but Bisque might have one or two spare boards about.
Although I think I read that a few people in the US were upgrading to Series 6000 boards, so maybe Astromart might be the best place to look for 5000 boards.
