Symbolics Space Cadet keyboard review (Honeywell Hall effect 4B3E)

As gumby says, the Space Cadet keyboards, being Microswitch Hall effect-based, were a bit spongy due to the big plastic case, but the switches themselves were dreamy. But the whole experience was still not as satisfying as the original Knight keyboards, I suspect because the Knight boards used the original, larger switches, while the Space Cadets used the smaller. Chyrosran22 on Youtube explains all this ( [link] and [this video] ). By the way, after 40 years of despairing over the loss of Hall effect switches (I nursed a Space Cadet Livermore Labs clone from a group buy for some years into the mid-80's), there are now two keyboards using this technology, and I'm loving the one that's actually available. Steelseries Apex Pro is what's now shipping, and it's a dream. ( [link] ) The Input Club Keystone is still coming, slowly ( [link] ), but I'm also really looking forward to trying it.
