Editing Hi-Tek Series 725 second generation (section)

===AT===
The AT style keyboards had a key layout based on the IBM AT keyboard. The layout is identical to that of the IBM. The case design is also similar to the IBM. Early models lack the status LED panel, instead having the status LEDs integrated into the Num Lock, Scroll Lock and Caps Lock switches and key caps. Later models have a status LED panel very similar to that of the IBM. The AT uses a different PCB design than XT. The PCB also feature anti-ghosting diodes which provides N-key rollover. A large screw near the space bar switch grounds the PCB to the switch plate. This PCB is identical to that of the 1st generation AT keyboards. Curiously, despite having the dedicated status LED panel, the 2nd generation AT keyboards continued to use LED switches for the lock keys.
