Below is a Cherry B70 Pro keyboard. The keyboard mechanism model number is B70-05AB. According to the 1979 Cherry Catalog, the clear anodized aluminum and walnut keyboard housing is model number B99-18AF. The description of the keyboard on page 21 of the catalog states:

“A versatile, reliable PROfessional style keyboard. Ideal for personal computer and hobbyist applications. Modifiable to add total obsolescence protection. Versatile enough to grow as your system grows.”

This ASCII keyboard is more fully documented in the “Meet the Pro” Cherry brochure with schematics and feature descriptions. For it’s day, this would have been the “Cadillac” of Cherry keyboards complete with Cherry manufactured housing. Much like I consider the Alps AKB-3420 keyboard as a “reference” keyboard, I consider this Cherry B70 Pro as a “reference” keyboard as well. It is a classic example.

Here are some pictures:
