Apple II

Hello! This is my first post on this forum, and after doing a lot of scouring around for info about the Apple IIe I ordered off of ebay and about some related modern solutions for software, I thought I'd sign up here to share my experience so far and ask some (hopefully educated) questions to shore up what I'm still unsure of. I dug up an old Apple iPod Touch (felt poetic, also I misplaced my usb-c to 3.5mm adapter for my phone) in order to convey MECC-Computer Inspector onto a disk via a .wav "cassette" to run some checks and confirm what I have.

What I'm working with:

I am looking for the files needed to program replacement GAL16V8D chips for my MicroDrive. This is the original version - not the Turbo one. There are three GALs on the board. The board does not have any silk screen indications of the what the parts are, so I will call them left, middle and right with left being the one on the left as you are looking at the component side of he board with the edge connector pointing towards you. The last time I powered ny Apple ][ GS on with this card installed, the GAL on the right decided to release its smoke into the wild.

@here Ok, I'm going to make a plea.

The Apple II FujiNet's smartport interface behaves differently across firmware versions and smartport adapters.

We need help to understand _WHY_ and what we're falling short on.

We need people to help with a $10 USB logic analyzer and a copy of PulseView to compare the Unidisk 3.5 and other SmartPort devices against our firmwares, and see WHERE we are failing, to understand the timing tolerances, so we can figure out where to focus our efforts on the firmware code.

Anyone know where I can find an ethernet adapter for sale? Seems like the recommended ones like uthernet aren't in production anymore.
