The system featured an oversized cabinet that held up to 16 expansion cards, or could be further expanded to 48 cards with an external expansion cage. Next came the instruction mnemonic, then the parameters. In early , Fred Allard, formerly of Ampex ‘s Memory Core Division, was asked to design a new core memory system for the systems rather than continue purchasing them from Ampex. HP supplied a three-pass assembler for the machine, [56] using a column-delimited format. Modify your browser’s settings to allow Javascript to execute.

Most executed in one memory cycle, or 16 clock cycles, [45] although indirect addressing and the ISZ could use up to 36 cycles. Led by Magleby, the new division completed the design as the A, which was demonstrated 7—10 November at the Joint 2100ppc Conference 21000pc San Francisco.

All of these models were replaced by the HP series in[1] and then again as the 21MX series in when the core was replaced with semiconductor memory.

HP purchased the company in and merged it into their Dymec division. The main difference between the M and E was that the E used clever timing to improve the speed to about twice that of the M.

The Virtual Agent is currently unavailable. This stood for the “M” processor and the “X” memory, as the memory control systems were separated from the CPU in 1200pc to provide flexibility in case the chosen 4k parts were changed during production.


These were about twice as fast as contemporary gp core, and much smaller, allowing 32kword machines to be built in a like form factor. The system featured an oversized cabinet that held up to 16 expansion cards, or could be further expanded to 48 cards with an external expansion cage.

Learning that Westinghouse owned a trademark on that name, in they changed it to Dymec. Physical Specifications – The least significant 10 bits of the register were then placed in front of the original bit displacement to produce a bit address.

Please use the product number and serial numbers of the new product to validate warranty status. Inthe division decided to move to 4kbit SRAM memory chips in place of core.

Some device numbers were used by the system itself. How does HP install software and gather data? This was used starting in the C models. At the time they made this decision, 4kbit SRAMs were not actually available, so experimental machines using the core from a series were used initially, replaced by 1kbit SRAM.
