I just received the Newton Non-NTI motherboard and listed some motherboard+ "SCC" ACI bare board bundle on ebay for $115 plus shipping. I have around 13 Datanetics KBs which will be shipped with each bundle as gift in first-come-first-serve basis. There are the two designs, one takes both Datanetics and Cherry 3-pin switches with no drilling needed (I've got 3), while the other one only take Cherry MX switches with 5 pin but drilling IS needed (the fab didn't make the holes as unplated; I've got 10). As the big board costs even more than before to make and is slow to move, this should be the last Newton boards but I will sell for less than before. These are not based on the open-source gerbers, but the ones I worked on in 2012. Mostly like this will be the last batch of Newton motherboards to fulfill the more demanding needs.
Like some other folks, I am almost done with eb*y, you can't imagine you can't even find your listing using the "search" function, and I just re-list the bundle almost 24 hours ago, it still doesn't receive a view (0 view at the time of this message), but I pay the promotion adv fee which is supposed to increase visibility. It don't even show up when I click my own store or "see all items".
Here is the link to the listing if someone is interested in the Newton Non-NTI motherboard (aka pre-NTI, or Newton 1) board with the matching SCC ACI and feel more comfortable . I consider this to be the last batch. The more cost effective fabs (eg JLCPCB, PCBmay etc) just don't make the boards as required, well, I know as otherwise that means they can't combine the Newton boards with other customer orders on the same work panels to save costs, but I don't want the Newton boards to be ordinary.
Direct transaction on the board bundle is $95 plus shipping. The free Datanetics KBs are all gone, sorry. I am also going to offer a few sets of hand-assembled Newton with ACI, CMX keyboard and program cassettes, which will be subject to board and component availability. Just PM me.
