The MCS-8™ parallel 8-bit microcomputer set is de- signed for efficient handling of large volumes of data. It has interrupt capability, operates synchronously or asynchronously with external memory, and executes subroutines nested up to seven levels. The 8008 CPU, heart of the MCS-8, replaces 125 TTL packs. With it you can easily address up to 16k 8-bit words of ROM, RAM or shift registers. Using bank switching techniques, you can extend its memory indefinitely. The PL/M™ High Level Language is an easy-to-learn, systems oriented language derived from IBM's PL/I by Intel for programming the MCS-8 and future 8-bit micro- computers. It gives the microcomputer programmer the ‘same high level language advantages currently available in mini and large computers. By actual tests, PL/M pro- gramming and debugging requires less than 10% of the time needed for assembly language. The PL/M compiler is written in Fortran IV for time-share, and needs little or no alteration for most general purpose computers. Intellec™8 Development Systems provide flexible, inex- pensive, and simplified methods for OEM product de- velopment. They use RAM for program storage instead ‘of ROM, making program loading and modification easier. The Intellec features are: © Display and Control Console © Standard DMA channel © Standard software package ‘© Expandable memory and 1/0 © TTY interface © PROM programming capability The Intellec contro! panel is used for system monitoring and debugging. These features and the many standard Intellec modules add up to faster turn around and re- duced costs for your product development. And, There’s More. Intel's Microcomputer Systems Group continues to de- velop new design aids that make microcomputer system- building easier. They will provide assistance in every phase of your program development.
