Microbee 'Premium' to 'Premium Plus' upgrade
Our Limited Edition Microbee Premium Plus computers were quickly sold out when first released back in 2012. They are still highly sought after.
Although we will not be manufacturing any more of the Premium Plus kit, you can now upgrade an original Microbee Premium Series computer to the Premium Plus.
This upgrade will only be carried out by Microbee Technology - that is, you will have to send in your working Premium Microbee to us & we will upgrade it. We will fit the new coreboard and do all the neccesary changes to the main board to complete the upgrade. We also provide an SDcard loaded with disk images for normal Z80 Microbee mode and uClinux.
