Hi, I am new to forum. I know there's a lot people that might help me. I have a old XT clone, Ericsson branded, and I have problem with keyboard, because I don't have original one. XT keyboards don't pass POST, saing just "KEYBOARD ERROR". AT keyboards do, but still it's unusable, because compurter not recognizing a pressed keys, but only beeps. I assume, taht Ericsson PC have their own non-standard Keyboard protocol.
Anyone knows something about this? Or how to make Arduino-based converter for AT? (I tried a lot of AT-XT arduino projects, no one works.).
I will be really gratefull for any TIPs.
