Hardware Description

The 9835A was a lower-cost version of the 9845A. It used the same housing as the 9825, with three expansion slots, single tape drive and optional 16-character internal thermal printer. It had the same twelve-inch screen as the 9845, but without graphics capability. The 9835A was program-compatible with the 9845A. The 9835B cost $1200 less than the 9835A and included a single-line LED display instead of the CRT display. ROMs for the 9835 were unique to that machine, and not compatible with the 9845 or 9825.
