Mega ST keyboard, which Cherry MX Black type?

[pixelpusher]

Hi all,

I was looking into replacing a broken Cherry MX Black switch on a Mega ST keyboard. Browsing Cherry's key offerings I saw that there are two switches that could match: One with 3.7 mm travel (MX 3A-11nn), one with 4mm travel (MX 1A-11nn).

As I can't find a type code on the original switch, I tried measuring the key travel - it's somewhere in between those offerings.

Does anybody know which exact type was used by ATARI?

Do you know if both types existed in 1987 or so?

Good hint - turns out of those only the MX 1A existed in 1987.

I replaced mine with cherry browns and they're absolutely beautiful.

Did you do the whole keyboard? Just wondering how much that cost and how long it took.

I just need to replace one switch, but if you're interested in replacing more:

For 50-99 pcs the price is around 0.53 EUR per switch, 0,44 EUR per switch for >= 100 switches.

There are also two so called "Developer kits" for MX Silet Red and MX Speed Silver switches which cost 40 EUR and include 110 switches.

Best regards,
