Thats interesting because another replica I'd really like to make is an Acorn System 1
I'm still struggling to find the time to finish my MK14, which makes me feel a little guilty given the amount of time and effort others have gone to in helping me. My proms travelled all over Europe from person to person until I got a working pair! So I fully intend to work out a programmer when I have time and publish the design to save others the pain, but at the moment I have other priorities. Also, due to having to use my "lab" as a storeroom for stuff I retrieved from Mums house before we sold it, I can't find my test equipment and can barely get to the bench!!
Still, one day things will be "back to normal" lol....
