Sanyo MBC-2000 / 3000 keyboard

Nice. Looking at the layout, it should be quite useable with some creative mod placement. And vitally, given those harebrained vertically stacked arrow keys, the HHKB Fn key is present:

I wonder what to do with all those function keys!

no lack of function keys that´s for sure!

The color scheme of this keyboards reminds me of the Sharp MZ series of computer, maybe the same manufacturer; the sound of the keyboard is arousing; the way it differentiates zero and letter O is hilarious...

What a good looking keyboard!

Thanks and welcome to DT! I only found out about a year after I got it which computer it belongs to.

I dig the color scheme and that's a functional keyboard if I ever saw one.

The imprint looks remotely cherry mx compatible but I bet a minute deviation makes that dream evaporate.

I wish my garage sales had rarities like that; it looks in incredibly good state though so my guess is that wasn't a dollar shop haul ^^

It's pretty large and bulky which may not come across in my pictures.

Sorry this has nothing to do with Cherry MX. Here is the Fujitsu Leaf Spring 1st generation switch explained in detail:

It wasn't crazy expensive, obscure ones like this usually aren't.

The functional part was more of a joke relating to the 22 top row keys..! Aha

Nothing to do with Cherry MX regarding the keycaps?



I can see that the switch are as close as black and white, but the cross mount look similar.

OK sorry.

I doubt MX mounts on Fujitsu Leaf Spring 1st generation but I never tried and I'm not about to. If you could see these keycaps in real life you'd agree they have nothing to do with MX.

What I wrote on the wiki:

The keycap mount dimensions are a fraction of a millimetre too large to fit Cherry keycaps; keycap insertion is very stiff. Testing with a modern Signature Keycaps novelty keycap yielded borderline success, while testing with a 2009 Filco keycap resulted in what appeared to be whitening of the plastic from stretching. Attempting to use Cherry MX mount keycaps is liable to lead to split keycap stems.

So, almost, but not quite. However, you may well find that you can harvest the Fujitsu keycaps — I only have NOS switches, not the keycaps to go with them.

Life's always like that. Almost working as expected but totally not exactly quite like the opposite.

Good to know thanks I probably read this and forgot about it. Like I wrote the one thing that struck me is that tiny super sharp metal bit at the very top of the slider, I really wonder what possible function that could have?

I've skimmed through the patent

Figure 4 denotes the skimming metal part as the top of part 15a.



Only mentions are :

Referring to FIG. 2, the drive rod 51 is formed by insert molding of a plate spring element 15. A support-portion 15a of the plate spring element 15, having a shape as shown in FIG. 4, is used as the core of the molded body, and an upper portion 16 is the shaft on which a key top (not shown in FIG. 4) is inserted.

and

The frame 26', having the so-formed plate spring elements 15, is transferred in a direction of arrow E and by a molding machine (not shown) disposed at the position F, drive rods 51 are continuously molded, with the support-portion 15a of the plate spring element 15 being as the core

So my uneducated guess is that the sharp metal is present as a manufacturing requisite and serves no functional purpose. (?) It'd be there to pierce the plastic? Serve as a point to hold the piece during a molding around it?

Hmm interesting. I'll have to get the Sanyo out the basement and have another look it's been in storage for well over a year. I clearly remember pulling the keycaps required some effort but if that metal tip has anything to do with that...
