NMB RT-8700 series keyboard

History

RT-8700 is a series of full-sized keyboards manufactured by NMB in the mid-’90s. They came with the fifth generation Hi-Tek series 725 switches, which is the last generation of its type.

Unlike the 4th generation boards, these have a smaller footprint and thinner bezels. Here is the original Ad for these boards.

NMB used to market them as the “Right Touch” keyboard, and these were the alternatives of the venerable IBM Model M and Northgate Omnikey 101s, among others.

Acquisition

I was lucky enough to get into the largest vintage computer keyboard group-buy in history. Inoznez used his parent’s farm to store the boards and slowly shipped them out all over the world.

Initially, I wasn’t aware of this, but I got an entry when another buyer had to drop out of the deal for some reason. I got ‘10’ boards for myself and helped proxy some more for the local keyboard enthusiasts.

There were many layouts, such as German, Swedish, Norwegian, etc and I got one from each. This board is the one with a Danish layout.

Build and Features

The case is probably made of thin ABS and it’s very poorly made. The whole thing creaks a lot, even with a minor flex. The keycaps however, are made of thick PBT with dye sublimated legends.

This particular model has clicky Hi-Tek series 725 switches(black). These switches are colloquially known as space invader switches due to their resemblance with the 8-bit space invader arcade game characters.

The switches feel a bit stiffer and aren’t as smooth as the white space invader switches I got a few weeks back.

I got 6 of these boards, and I have planned to harvest the switches and caps from one keyboard and build a custom 60% board using the PCB and Plates from the latest group buy.

Restoration

These boards didn’t need any restoration, because they are practically new. I got an active PS/2 port to USB converter, and it worked with my computer.
