Validated design for 1130 core loader (DMA version) sent to fab after testing session

BREADBOARD TESTED NEW DESIGN

I changed the breadboard to the new design I created for the DMA loader circuitry and put it through its paces. Initially I had a problem with switch bounce but a debouncing pushbutton on my Cadet did away with that issue so that I could test with confidence. 

I expanded the test setup to show the state of the control outputs I generate as the state machine operates, to be certain they were correct. I drive both -CS Level 0 Request and -File Data Entry Gate low with open collector chips - temporarily added pull up resistors to be able to see the outputs. I also drive the enable line for the Address and Data words; when a bit of an address or data word is 1, it will pull the output low but only when enabled. 

PCB DESIGN SENT TO JLCPCB

I packaged up the Gerber files and drill information in a zip file and uploaded it to the fab. I chose a blue color for the solder mask with white silkscreen images. It will take 3-4 business days to complete manufacturing, then 3-5 days for shipping. The components are all waiting at the shop for the boards.
