@jay_s_uk Thanks, i will try

@jay_s_uk I've a modified firmware that are compatible only with the v1.0. I would like to avoid of doing a porting to the new version. I thought that as manufacturers you have some old boards in stock

Hi,
I need to order a Duet 3 Mainboard 6HC V1.0 for my printer . The problem is that i cannot find this version of board. All reseller that i asked have the new version of board 1.0.2a. I've a modified firmware that are not compatible with the new board.
Where can i find this version of board?
Thanks
