Yep, passing on that one too. Not interesting enough for what my tastes even if they aren't too common.

ITW magnetic valve switches, for those wondering. I've been mulling it over for a little while, I think I'll pass. Neat keyboard though!

Ooooh, that looks like it's the predecessor to my SWA-4300. Even has the same badge. Cool, never knew that model existed.

How to sell a Fujitsu Peerless keyboard for $85

Step 1: Remove keycap and switch top, exposing spring
Step 2: Call it a buckling spring
Step 3: Wait for a sucker

Someone will be sorely disappointed and either realize it's not a bs board or hate vs boards forever.

This may be an ANSI magnetic valve or magnetic reed 'board. Cortron is a promising name...

Cortron are the ones who made ITW's MV switches before they sold the tooling to Devlin, so that might very well be. They still use a type of magnetic switches for their keyboards to this day. AFAIK Cortron never made a flimsy keyboard xD . The packing plastic also looks like like that on my MV Zenith board xD .

Step 2: Call it a buckling spring

To be fair, it is a buckling spring mechanism, just misleading.

The spring buckles? And even if it did, the (catastrophic) buckling is not the mechanism.

As far as I've been able to tell (and the wiki seems to agree), the spring buckles which creates the click. The actual actuation is done by the membrane and domes, but it's really not that much different from IBM buckling spring, despite feeling significantly worse.

I don't think the feel of the unstabilized keys is that bad. There are many that are much worse. The stabilized keys on the other hand are another story. The posts seem to mimic the Model M style but dont work as well. They could be decent if they swapped the location of the switch and stabilizer peg so that the switches were under the in-board portion of the switch.

[Blaise170]

No argument from me there, I've definitely experienced switches that were much worse but comparing only IBM to Peerless, I find Peerless to not be so nice.

Is "buckling" always sideways or can something buckle downwards too? Btw I really don't see how they're clicky, they just don't sound clicky at all xD .

[Blaise170]

A buckle would be any motion outside of the linear motion of the spring. I've had a bunch of Peerless boards and some sound clickier than others.

Well in that case it shouldn't be buckling at all I think because the spring is quite well-retained in the sock and slider well, there's little room for it to move around. Not to mention how hard it is to design a system that actually buckles properly =o .

If you look at the mechanism and the way the spring sits enclosed it cannot "buckle" like in Model M I believe. This is one mystery we don't need to solve IMO. And just like you say Blaise170 my Fujitsu FKB4700 is also erratic in sound and feel across the board. Fujitsu Peerless is such a strange one.

DT wiki:

The mechanism by which the click is achieved is unclear, and may come from the shockwave caused by the dome collapsing under pressure from the cylinder.

Yooo what is THIS? The layout is the EXACT same as one of the old Beamspring keyboards

[Muirium]

That's an XT layout by the look of it. Pretty common, what with the original IBM PC using it.



But you're right that it's a bit beamspringy, having spherical doubleshot caps instead of the XT's cylindrical dyesubs. The stepped keys either side of the spacebar are in keeping with the beamspring style as well.

[OleVoip]

I saw that board in the morning and it gave me an itch the whole day long. I'm glad it's been sold now.

I asked the seller to draw a cap from the Siemens he also offers, and it's a rubberdome one, as already was suggested by the lasered caps, http://www.ebay.de/itm/252388379076

[Dra]

The layout and just everything...
It can't be a coincidence, can it? seller even accepted the 45€ offer.

Flat-topped 3, if I'm not mistaken. Prolly Micro Switch.

Yes I think so too. And a nice one at that.

[Dra]

We shall see! I'm having high hopes, either way everything's a bit 'off', I couldn't find anything on the keyboard except the familiar layout, we got the UOA diaeresis which is off for probably both, Micro Switch and Beamspring boards

[ohaimark]

The number pad keys are hilariously long. Look at that 0.

[Redmaus]

Yeah it would be easy to use without shifting your hand. Looks like someone likes to use the 0 key with their pinkie?

The Heathkit link is broken, but it may be a Stackpole too. I had a 1978 Heathkit once that was stackpole, and it was interesting but long-throw stiff linears are not my cup of tea at all. The beast was awesome, however, with ultra-thick doubleshots in black with multiple-colored legends.

Nice - complete plain PF1-24 upper set!

Wasn't somebody looking for that dual-screen key in the left F5 position?

[Redmaus]

The blue dyesubs are also really nice
