I have an old IBM keyboard that was found my step fathers stuff after he passed away, I was wondering if any has any information on what it is or what it's worth? It's part number is 84G6294, I can't seem to find anything online that give much information about it. Is it worth trying to sell? Seems in such good condition for an old keyboard that I can't brig myself to throw away, do you reckon it will be of value to someone out there, I will attach pictures.
