In my last update I said if all is well … Well all isn’t well.
The new boards had a flaw in them which I had introduced when trying to sub out one part for another. Once I figured that out, I proceeded to test a modified board and when doing extended tests I started seeing more timing issues. At this point the only model with full stability is my Enhanced IIe.
In an attempt to diagnose the issue, I have found it very difficult to take accurate measurements given the full SMT nature of the board. So I have ordered some new PCB’s with proper test points on them still using all the same components I would plan to use in production.
I will post another update once the new boards are in hand.
Update: Boards are back, stencil arrived today … parts have also arrived.
Update: Test build build to start soon
