Improved keyboard controller — ZXNet «hardware.zx»

From Nikolaj Amosov To All 10 November 2004

Greetings, All! I decided to revive the Zone PC keyboard controller. Here I look at the description sheet and see that as an improvement from "freezes and sticking" suggest installing a 430 Ohm resistor and capacitor 300-430 pF. I would like to know exactly what yours is is there a capacitor? Otherwise I put something from this range, which I had, but the keyboard is still buggy. Delivered trimming resistor and went through the range of 430+-100 Ohms, so and not finding a non-buggy state. Even better without a resistor - sometimes it “sticks”. So far only the mouse works...

They decided to kill two birds with one stone - to ensure the performance of both AT and XT keyboards right away. One of the contacts for one of the keys is an input for the other is a way out. Air conditioners with air conditioners are designed to help the situation. Because of this and It's buggy and works differently with different keyboards. I didn’t save the diagram, but if you want, you can determine what is needed there TEAR OFF. XT keyboards will stop working, but AT keyboards will be bug-free work EVERYTHING.

Hello Vlad! Thursday 11 November 2004 20:16:56 Vlad Sotnikov -> Nikolaj Amosov: NA>> I decided to revive the Zone PC keyboard controller. VS> What is better than the native Speck keyboard? :) Well, let it be both. By the way, before I only had PC keyboard, but I installed my own one so that with my friend cut in DBLASTER and CHOPPER DUEL without interfering with each other;) True, I was really upset when I saw that the PC controller blocks the native keyboard when the button on the PC keyboard is pressed :( I don't respect joysticks...
