Two of the finest names in electronics, Heath Company and Digital Equipment Corporation (DEC) combine to bring you the world's first 16-bit computer priced within reach of the general public!
$1295.00
The new Heath/DEC H11 personal computer combines the advanced performance-proven hardware and software of the famous LSI-11 with Heath's expertise in kit design and documentation to bring you a personal computer of almost incredible power and performance. Equivalent commercial versions of the H11 would cost literally $1000's of dollars more!
The LSI-1 bus has 38 high-speed lines containing data, address, control and synchronization lines. Sixteen lines are used for time multiplexing of data and addresses. All data and control lines are bidirectional, asynchronous, open-collector lines providing a maximum parallel data transfer rate of 833K words per second under direct memory access operation.
The fully wired and tested KD11F board contains the CPU with eight general registers which serve as accumulators, index, autoincrement/autodecrement registers or stack pointer; and a 4096x16 MOS semiconductor memory. Additional cards can be added to expand memory up to 20K in the H11 cabinet (32K words total).
The backplane/card guide assembly holds the microcomputer and up to six I/O and memory modules. All LSI-11 bus data control and power connections are routed on the printed circuit backplane to each module location. The backplane/card guides are fully compatible with all standard DEC LSI-11 accessories.
An efficient, well designed power supply provides the required DC voltage for the LSI-11 as well as all accessory modules. The supply features overvoltage and overcurrent/short circuit protection, power fail/automatic restart and a built-in fan for quiet cooling The dual primary power configuration can be connected for 115 V, 60 Hz or 230 V, 50 Hz AC.
Other features of the H11 include single-level, vectored, automatic priority interrupt, real-time clock input, ODT/ASCII console routine/bootstrap resident in microcode. The H11 is supplied with versatile PDP-11 software (described below) which uses the famous PDP 11/40 instruction set with over 400 commands.
The H11 is housed in a rugged metal cabinet with structured foam side panels, 6-1/2" H x 19" W x 17" D. For 110/220 VAC, 50/60 Hz.
Kit H11, Shpg. wt. 43 lbs. ............... 1295.00
PDP-11 software included with the H11 consists of: ED-11 editor; PAL-11S relocatable assembler; LINK-11S link editor; Absolute Loader; ODT-11X debug program; IOX executive program; DUMP AB and DUMP R; BASIC (with strings) and FOCAL (4K and 8K versions). The software requires a minimum of 8K memory with 12 to 16K total recommended for maximum capability. See software License agreement, next page.
Fully Wired and Tested KD11F Circuit Board. The "heart" of the LSI-11 is the standard DEC LSI-11 microcomputer board. The 16-bit CPU functions are contained in 4 silicon gate N-channel MOS LSI integrated circuit chips for high reliability and superior performance. The 4096-by 16 read/write MOS semiconductor memory is composed of LSI 4K dynamic RAM chips for fast access time with low power consumption. The board is fully wired and test to facilitate kit assembly and provide greater reliability and less chance of error.
The compact, efficient power supply uses less power to operate and generates less heat than conventional supplies. Has overvoltage and overcurrent/short-circuit protection, plus automatic power-up and power-down sequencing for high reliability and long life operation. A built-in quiet-running fan provides efficient cooling and prevents heat buildup.
Rugged steel chassis and extra-thick backplane with heavy, solid connectors for added strength.
Card cage swings up for easy access and service even when the H11 is operating.
Accessory boards slid directly into card guide and are held securely in place. All card connectors are supplied for easy expansion.
H11-1 4K Memory Expansion Module. Plugs directly into H11 backplane, adds 4K x 16-bit word capacity to H11 memory. Access time, less than 500 nS. Fully compatible with PDP 11/03 and other LSI-11 backplane machines
