Picking up from 80386 DX Build (rehsdonline.com), I am transitioning my 386 DX build to an EATX form factor, incorporating changes up to this point. This will be a running blog post, so check back for updates.
I start by getting the upper and lower PCBs connected with a pair of EuroDin connections. I also check how the PCBs will fit the EATX chassis that I am using.
Next, I prepare the upper PCB with capacitors, resistors, sockets, and power connectors.
I next populate the sockets.
First power on... no smoke.
Code running successfully, and using the Teensy-based debugger...
Versatile Interface Adapter (VIA) running...
SPI running...
VGA output and CLK2=24 MHz, CLK=12 MHz...
Priority interrupt controller (PIC) and an Arduino Nano to support keyboard and mouse...
IDE controller and FreeDOS loading...
