For those that are too "new", that was AFAIK, and RCA 1802 with 4k of static ram. Very slow, and very low power. But having experience codeing for it in the later 70's, it was both stable and if the coder did his job, bulletproof. The program I wrote for it was still being used 20+ times a day by the production people at KRCR-tv in Redding CA, in 1996. Considering I wrote it in 1978, that 18 years of non-stop use at a tv station, its like The Simpsons, who just passed Gunsmoke as the longest running program ever. I suspect it was still in use during the day of June 30th 2008, the last day we broadcast in NTSC. For a program that made liberal use of self-modifying code, I'd say that was amazing. Lets also say that the 1802's architecture was also different from every other cpu in the 8/16 bit field then. The TI 9900 was the only simpler one, stripping any internal register that addressed memory directly.
