What Is in It

  • Making PDFs with CutePDF Writer.
  • Upgrading the Einstein's ROM from 1.1 to 1.21 and System5, and the risk of running out of memory.
  • Adding BASIC commands, and the BASIC token table in Einstein Magazine 103.
  • The annotated 1.21 EPROM disassembly that went to Stan Gibbs, and a warning about testing EPROM changes under emulation.
