For now, I can load games only by listing (hex code) via terminal, but I've designed two ways to load games on my apple-1 replica/baffatari.

If you have an Unocart or old cartridges, you can use the backplane's peripheral port to attach a cartridge expansion. This allows you to run games directly from the cartridge.

But, there is the option to load the games via SDCARD... The SDCard board is based on P-LAB's "Apple-1 microSD storage card".

Both boards will be available soon... Can't wait to post videos showing them working :)
