Finally an ALPSaver of my very own. I was very lucky to find it randomly on the Yahoo! Japan Auctions site. It has buttery smooth Alps SKCC cream switches.

This one is fairly unique with it's industrial gray case and extra circuitry designed for use with a radio transceiver. The keyboard supports two modes: CW (Continuous Wave) and RTTY (Radio Teletype).

I was even able to find the manual for this keyboard: YK-901 Manual

Alpsavers are indeed tres boss. The Kishsaver of the east! And I’ve got to say that picture of radio gear with one in action is way nerdier than the mundane bank jobs the ‘lil IBMs were made for.

Are these guys converted yet? Or are they at the same tantalising stage the 4704 was at when I got my paws on mine?

I hadn't heard that one before.

Well zrrion converted his but I don't know the details and my board looks a bit different so I'll have to dig into things.

Mine wasn't converted it was hand wired (I damaged the PCB like a dunce, making conversion impossible)
