It's that time of year again, time for a new clone!
Really I should be working on the LC 475 board but 6 layer boards and desoldering 208pin QFP's is not seeming appealing at the moment so another project was needed
I have been after a Apple II for a while but they go for way more money in the UK than I am prepared to pay so building a clone one seemed like the right way to go, while clones of the original apple PCB are available (and I actually have a few I never finished assembling) building a clone of a clone seems like more fun
Really the idea came while watching a recent Adrian's Digital Basement video on a low cost clone of the apple II during which he produces a unpopulated clone PCB, my immediate thought on seeing the board was "I need to ask for scans of that" but as it tuns out I didn't as he scanned the PCB while troubleshooting and uploaded those scans to archive.org
The board is a pretty simple 2 layer design so shouldn't take too long to redraw in sprint, the only complication being that some areas of the scans are not the clearest but as scans of the accompanying schematic where also uploaded this should not be a big problem.
Current status of the board is this: (Most pads placed, just needs the connectors / trimmers placed before I can start drawing tracks)
once this is all done I will be uploading the design to github for anyone who wants to build their own clone
