Series 200 Models HP-9816, HP-9826, HP-9836, and HP-9836C

Technical Computers

Hewlett-Packards Series 200 included the HP-9816, HP-9826, HP-9836, and HP-9836C. They were based on the Motorola MC68000 16-bit microprocessor, with 32-bit internal architecture. The HP-9826 was the first model of the series being introduced in late 1981. The HP-9816 was introduced during the latter half of 1982. The HP-9836 was introduced after the HP-9826 during 1982 or 1983.

These computers were standalone units, or instrument system controllers for laboratory automation or production test. With peripherals, they also performed as technical workstations in computer-aided engineering (CAE) design and test applications.

The HP-9816 had a built in 9-inch (229 mm) CRT, a detached keyboard, and memory from 128Kb to 768Kb. External printers, disc drives, and other preipherals could configure it as a standalone workstation; or it could be connected to a Shared Resource Management (SRM) with other HP computers, sharing printers and disc drives. HP-IB and RD-232-C interfaces were built in.

The HP-9826 featured a built-in 7-inch (178 mm) CRT, a built-in 5-1/4 inch flexible disc drive with 264Kb capacity, and up to 2Mb of memory. With a larger base and keyboard than the HP-9816, it could be placed in a rack with other electronic devices and instrumentation. With a built-in HP-IB interface it was suitable for CAT applications, where an integrated system was required.

The HP-9836 featured a full 12-inch (310 mm) CRT, two built-in 5-1/4 inch flexible disc drives, and up to 2Mb of memory. Its larger screen and mass storage capacity (528Kb) tailored it for CAE applications such as engineering design and analysis. It also had a built in HP-IB interface.
