While considering my next CPU card design, I decided to first take a look at the Reset circuit design.
My first MECB CPU card faithfully used the same “old school” reset circuit design, as we’d used in the early days. That is, a capacitor, two resistors, and a Schmitt triggered input chip.
Now, there’s nothing wrong with that, but I figured there’s probably a tidier “Retro friendly” solution these days.
Join me, as I present and then test the operation of a “Microprocessor Monitor” based alternative solution.
