Hello everybody,
I'll start by introducing myself. I'm an electronics engineer and I'm trying to develop an XT-protocol keyboard for a customer who wants to use it on his Rosemount DCS system from about 20 years old, sounds strange but apparently those rosemount systems can survive a nuclear attack. It has been installed for about 12 years and the only thing that broke down was a hard disk because someone tried a hammer on it.
Does someone know where I can find the code tables and a firm description on how this XT protocol works. It is different from AT, that I know.
Second question, I would have to test the encoder, the only problem is, what computer do we use for this? The old first IBM PC would do, but is too expensive. Is there a different solution available?
I've been googling for the last few days but I can't filter out anything usefull.
Best regards,
Christof
