Intersil Intercept Jr

To Whom it may Concern: What is all this stuff about the Intercept Jr? I was the designer of that little demo computer way back in the 1970s when I was working for Intersil. If anyone get's this message, are there some specific questions you might have? I still have several of the early proto units in my garage along with a lot of the original documentation. I see that someone is asking about getting replacements for the little micro-interpreter chip used in this design. Unfortunately it is not really possible to get new chips because the original was really a mask-programmed CMOS ROM that Intersil was using the Intercept Jr as a demo vehicle for (in addition to the 6100, the CMOS RAMs, and the support chips). There was also a larger version called the Intercept that I designed and we built first which was a full-blown PDP-8/E equivalent with 4K of 12-bit RAM, a full front panel, and a current-loop async serial interface that could be connected to an ASR-33 teletype and would run a full set of Digital diags and 4K-version software. After I left Intersil I believe they continued to develop additional peripherals for the Intercept and the Intercept Jr. including a memory extension controller based on the Digital version, a floppy disk controller, some special Intercept Jr. demo plug-in cards used in various educational settings such as the 6100 training courses that Intersil offered to their customers. I believe eventually the Intercept was capable of running OS/8. That required a 2-bank memory of 8K of 12-bit RAM as I recall. Regards, Jeff Little Menlo Park, Calif. PS: don't forget that the PDP-8 was basically organized around 12-bit words, not bytes.
