6/1/2023 0 Comments Northgate omnikeyBoth protocols transmit a keystroke using a serial data transfer of 9 bits, but IBM has a start bit and Tandy has a stop bit. While the Tandy 1000 and IBM XT keyboard protocols are very similar, they are not the same. The computer type is set by a bank of dipswitches on the keyboard. Northgate indicated that its keyboard was compatible with the Tandy 1000 SX and Tandy 1000 TX computers. The Omnikeys support XT and AT keyboards and even some more exotic machines like the AT&T 6300, the Amstrad computers like the PC-1512 and even the Amiga 2000 & 2500 computers. I have long known that the Northgate Omnikey line of keyboards supported the Tandy 1000s. IBM avoided this issue by assigning the function to Ctrl+Print Screen. Press this key twice and, unless you have a printer attached to your computer, your computer will freeze as it vainly tries to print what you are typing on the screen. However, the really evil key is the Print key. People who do not know or forget how the Hold key works may think their computer has crashed. Both keys are next to important keys like Enter, Alt and Num Lock, The Hold key acts like a true Pause key, everything is frozen until you hit the Hold key again. While it does have F11 and F12, software made during the Tandy 1000 (except by Tandy) lifespan rarely used these keys.įinally, the Tandy 1000 has the dreaded Hold and Print keys. There is no Scroll Lock, and while there is a separate Home key, there is no separate End, Page Up, Page Down, +, -, or * keys. Typing mistakes are frequent with this keyboard. Compared to the IBM PC or IBM PC AT keyboard, it feels cheap. Its layout is cramped and awkward, its keys are mushy and there is no tactile feedback. The 90-key Tandy 1000 keyboard is not exactly a pleasure to use. And finally, the Tandy 1000 keyboard is the same keyboard used in Tandy's MS-DOS (but not IBM PC) compatible Tandy 2000. The Tandy 1000 joystick ports came straight from the Tandy Color Computer. The Tandy 1000 card edge printer port can be traced back to the TRS-80. To save development costs, Tandy imported some of its designs from prior, non-IBM PC compatible computers. The Tandy 1000 computers, more specifically the early Tandy 1000s, had many good features, graphics, sound, expansion, performance, integrated peripherals.
