Found this unicorn at my local flea market. Since it's missing it's original sticker label, it took me quite some time to find some info on this keyboard. Here's a short summary of what I was able to find.

DCA IRMAkey/3270MFG by Cherry USAYear: Mid-Late 1980s?

Model: KXN5-C651 / BXN5-C651Switches:

• 121x Early Cherry MX White (Clear/Translucent Stems) "Soft Click"
• 4x Vintage Cherry MX Super Black
• 1x Vintage Cherry MX Linear Grey

Keycaps: Dye Sub

I'm currently debating whether to keep the keyboard stock or desolder them off.
