Mini DIN 8pin. It uses async serial 19200bps with odd parity. I wrote firmware to hook up to USB.

That is a variant of the M-system layout. It is a Japanese phonetic layout.
M-system keyboards are so sexy... I would love to have one.

Looks similar to a PrinsValium's symmetric stagger layout and the key caps are labeled as messy as NEO or BEPO.
Did you find out the difference between the yellow and grey switches?
Is there any logical pattern?

That's a great vintage ergonomic/symmetric keyboard.

Doh .... another grey Alps CM switch, this time linear-LED type. Surprising how many colours exist in linear with the LED recess. Might be a stiffer spring version, to avoid accidental keypresses, same as the MX Super Black.7bit wrote:Did you find out the difference between the yellow and grey switches?

In the SIIG MiniTouch, the top row switches differ in that the slider blocks (that stop the slider going down too far) are 1 mm taller, reducing the travel by 1 mm, from 4 mm to 3 mm. Plus the spring is longer and more tightly coiled.

yellow needs 60g to actuate while grey needs around 120g. Popular green Alps goes with 50g and Cherry red with 40g for comparison.
I found very very heavy Alps on PC-8801 keyboard before, IIRC it required around 230g But it's being lost on messy desktop now

Cool.
Now 230 g is heavy, but this weekend I measured the Honeywell hall effect switches to almost 300 g with a force gauge.

Nah, different Hall Effect Switches. The normal weighting on the keypads (78g) http://deskthority.net/wiki/Honeywell_Hall_Effect.
I don't have an official weighting on the lighter and heavy versions of the switches.

Just a heads up for anyone that has yellow alps:
If they feel gritty just open the switch up and use compressed air to blow all the dirt out. I think the LED recess causes them to get dirty easily.
It will feel buttery smooth after.
