For those that do not know: This is the same keyboard type the old IBM XT/AT came with. Very "stiff" keys, with a very clear "click", very sturdy, heavy. Actually, pretty good keyboards, though I personally perfer to use a keyboard requiring a smaller force to press the keys. The old Cherries with the "click" type of keys were ideal. "Cherry blue" are not quite as reliable as the old series, are somewhat harder and more in the direction of the old "IBM" style keyboards. Still pretty good.
It is amazing the difference a few years make. I remember seeing many of the old IBM 'clicky' keyboards for just a few bucks when they were out of fashion and old-school. Now the prices are high and they are rare, same with all the hardware of the early PCs (try finding a Hercules graphics card, sometime

). Fortunately, they DO work great with a Lyra adapter.
Our Amigas, once plentiful and cheap, are headed the same way.
