Back in the hacking days for apple ii you would reprogram the eprom on the Apple II Firmware Card and could pretty much stop the CPU and at any address and hack away. With no internet people hosted BBS sites with slow ass modems to share all these hacks, quite the community over time. Long distance was expensive but that didn't everyone from hacking the phone cards and pretty much dialing for free. What's funny is all this continued on even when the first Mac was introduced, so more cracking to do. I had people buying and sending me program to crack, then share with the community. Cool to see someone document their efforts.
