IBM System/23 Datamaster: Difference between revisions

The computer presents itself with a pre-Model F keyboard with 83 keys. Internally, it used the very same components than the keyboard of the IBM PC would later. The only difference between them is that the PC uses a serial interface to communicate the peripheral with the computer and the Datamaster has a parallel interface. This change also implies that the code in the 8048 micricontrollermicrocontroller both carry is different. For this reason this was also one of the most common causes of not repairable failures.
