The author reflects on their employment history at Texas Instruments during the time of the TI Explorer Project, where they worked on one of the last Lisp machines that ran Lisp directly out of the microcode. The author had had extensive memories of those days, including memories of coding in Pascal and Common Lisp, debugging challenging issues, and working with an impressive early email system. The author also reflects on hardware-related memories, including the significant amount of memory used by the machine, and network-related memories that were often dependent on the Austin-Dallas bridge. The author ultimately believes that the machine would never have made money and was eventually sold off.
