Video Description

In the early 80s, the Apple II had was selling well but it was expensive. This is where foreign companies stepped in and started making clones. These machines were much cheaper but also illegal due to them using copied ROMs. Here we have one of these clones but this machine is broken, very broken. So let's try to get it working. Small correction: It turns out Franklin did not have a clean-room ROM, and were eventually found to be infringing. There isn't much detail about why Franklin was able to sell computers until 1988. See the pinned comment for more. Part 0: https://youtu.be/31WAE83FPoE (SMMC video featuring this computer) Part 1: This part!
