Flip Chip from a DEC KA10, containing 9 transistors, 1971 Quick Latch Memory Bus Terminator, used on KI10, 1973 KL10 Wire-Wrap CPU Backplane. The original PDP-10 processor is the KA10, introduced in 1968. [7] It uses discrete transistors packaged in DEC's Flip-Chip technology, with backplanes wire wrapped via a semi-automated manufacturing process.
Model As used the original PDP-10 memory bus, with external memory modules. The later Model B processors used in the DECSYSTEM-20 used internal memory, mounted in the same cabinet as the CPU. The Model As also had different packaging; they came in the original tall PDP-10 cabinets, rather than the short ones used later on for the DECSYSTEM-20.
The PDP-6 was expensive and complex, and therefore had not sold well. It was not long until it became clear that DEC was once again entering the 36-bit business with what would become the PDP-10. BBN started talks with DEC to get a paging subsystem in the new machine, then known by its CPU name, the KA-10.
The mass storage drawers, in such a case, would be divided between the CPU drawers, with a minimum of one per a CPU drawer. There are two models of mass storage drawers. One model may contain one to four 5.25-inch full-height non-removable, one 5.25-inch full-height removable or non-removable and two 5.25-inch half-height removable devices.
The PDP-10 was widely used in university settings, and thus was the basis of many advances in computing and operating system design during the 1970s. DEC later re-branded all of the models in the 36-bit series as the "DECsystem-10", and PDP-10s are generally referred to by the model of their CPU, starting with the "KA10", soon upgraded to the ...
TOPS-20 was based upon the TENEX operating system, which had been created by Bolt Beranek and Newman for Digital's PDP-10 computer. After Digital started development of the KI-10 version of the PDP-10, an issue arose: by this point TENEX was the most popular customer-written PDP-10 operating systems, but it would not run on the new, faster KI-10s.
The 18-bit PDP-15/40 connected to Massbus peripherals via a PDP-11 front end. An engineering goal was to reduce the need for a new driver per peripheral per operating system per computer family. An engineering goal was to reduce the need for a new driver per peripheral per operating system per computer family.
MACRO-10 is an assembly language with extensive macro facilities for DEC's PDP-10-based Mainframe computer systems, the DECsystem-10 and the DECSYSTEM-20. MACRO-10 is implemented as a two-pass assembler .
