In the meantime, I have received new supplies of PCBs, casings, cables etc., so if my previous stock sold out before you got the chance, now is the time. The kits now come with cables that already have plugs mounted on them, which should make assembly much easier as well as increase compatibility with some vintage computers.
The board itself has only had minor changes since the last batch. Remember that as always, this is open source hardware so you are free to have the board printed yourself from the gerber files.
Thank you for all your support!
