Description: About this Listing:This listing is for a very rare new-old-stock Intersil 6100 microprocessor. The 6100 was a very unique microprocessor. It was designed to run the software of the DEC PDP-8E mini-computer. The PDP-8 was one of the first mini-computers, and by far the most popular of the 60's and 70's. Vast libraries of software were developed and were available at little or no cost. Since the 6100 was designed to run the software of a 10 year old architecture, it is often criticized when compared to its peers. However, the 6100, for all its quirks, did implement a mini-computer on a chip. The 6100 adopted the PDP-8's 12-bit architecture and its entire instruction set. The CMOS microprocessor ran at 4Mhz and could address 12KB of memory (4096x12-bits). To run larger applications, the 6100's memory could be extended using a memory bank switching scheme that was created for the PDP-8. The PDP-8 was an extremely popular system. Introduced in 1963, the first PDP-8 was based on transistors. Later versions were based on TTL logic chips. That the PDP 8 was chosen to be the first mini-computer on a chip should be no surprise. By the end of the 70’s over 300,000 had been sold. Interestingly the 6100, and its follow-on the 6120, replaced the logic in some actual PDP-8s. They were used to power some DEC PDP-8 workstations, such as the VT78 and the DECmate series. Also, a number of cloned PDP-8s using the 6100/6120 were made by other companies. The 6100 was Intersil’s first microprocessor. DEC licensed the PDP-8 design to Intersil (and later the PDP-11 to Western Digital). The 6100 is unique among single chip microprocessors because of it’s single chip 12-bit design (the Western Digital PDP-11 is implemented on 3-chips). Because of the 12-bit design the 6100 could only address 12KB of memory. An Intersil 6102 could be used to provide 3 additional addressing bits that extended the 2 chip configuration to 48KB. The 6100 had two 12-bit math registers: an accumulator (AC) and a multiplier/quotient register (MQ) used to assist in multiply and divide operations.The chip offered here is a never used new-old-stock Intersil IM6100A-IPL microprocessor. The chip was made in the 22th week of 1984, over 30 years ago. The 40 leads are tin and the body is black polyresin. View the pictures to see the condition of the chip. This chip would be a great addition to your microprocessor collection.Want to see more AntiqueTech items?
