Afaik, the software mirrors all the CALI requirements even if it circumvents the OE patents. Cali has a spec to use the tamper bit, but there may not be a requirement to reset or update that bit, OR, the programmer could just ignore changing it. Not like it's an EPROM that comes set to '1's that you have to write zeroes and then open the case, zap with a UV light to erase or rewrite.

It's also not that hard to coment out a compiled line of code on a test computer. In Pascal or C++ it's a couple of [], much like the quote or font codes here.
