Description:

The 9826 was the first of the Series 200 machines. It came standard with a seven inch screen (300 x 400 dot resolution), 128K RAM and a single 5.25 inch floppy drive. The 9826 also had eight expansion slots. It was commonly used as an instrument controller. The 9826 family was also known as the 200 Series Model 26, 9000 Model 226 and 9000/226

In 1983, HP introduced a detachable keyboard option for the 9826A and 9836. This option (G3) was priced at $300 and only available in Europe.

The 9826A was very successful from the beginning of production. 295 units were sold during the first month (including 113 in Europe), a new record for HP desktop computers.

Collector's Notes:

The museum has found 9826s to be very reliable. As of 2015, 80 percent of units we see have been fully functional, although broken keys are not uncommon. The built-in floppy disc drive often needs some TLC to bring back to functioning order. The grease lubricant used on the mechanical parts of the drive can cause those parts to stick with age. This can be solved by cleaning with alchohol and replacing the grease with silicon oil. The read/write head of the drive often needs cleaning in order to read discs. Clean the heads using a 5.25" head cleaning disc. Some functions of the computer may not work because the unit was dropped, unseating one or more of the internal PCBs. A good first step in refurbishing these computers is to remove the top case and re-seat all internal PCBs. The memory boards for the 9826 are very reliable. These boards all require specific dip switch settings depending on how much memory the machine has, so be sure to check the manual when adding or re-configuring memory.

Some 9826A computers are the only models in the 200 Series that we have seen that contain boot ROMs that precede version 3.0. The pre-3.0 boot ROM machines will only boot from the internal floppy drive (or pluggable ROM O/S) and not from an external HP-IB drive. The start up screen for these early models gives only a memory count and a message about finding (or not) an operating system. The start up screen for boot ROM 3.0 and later also provides information on the self test status of all plug in cards as well as the built-in HP-IB, floppy drive and keyboard.
