Royal / Triumph Adler Alphatronic PC

[snuci]

Here is a Royal / Triumph Adler Alphatronic PC from 1984. I wish this was a better keyboard example because you can clearly see rust on the switch plate but I am considering restoring this plate and re-painting it. This is a fairly rare computer with a low profile keyboard with Futaba low profile linear switches.

Here are some pics:

Cool stuff as usual snuci, I just stumbled over this official TA Triumph-Adler page about the history of the alphatronic series.

I think the design idea of the circle around the number with the orange F-keys is interesting and aesthetically pleasing. I am assuming those would function as F-keys anyway.

I agree with you. I like that idea. It's hard to see but there is also a small "channel" above the function keys. Looks like a plastic label holder might have fit there to define what the keys do. I've seen this idea done with overlays on other keyboards of the era so those keys could be labelled anything. There is a cartridge slot hidden at the top right (there is currently a Micro Text cartridge in it). No labels were with it though.

It's unusual another keyboard having this switch!
Could you mind solder the switch to see which having the Futaba logo on the base?
My keyboard having the clone of it(black lock tab, original Futaba low-profile linear is the white lock tab)

Hi Terrycherry,

Sorry, couldn't get to it yesterday. Here's a pic. No logo.

A couple of more pics here (I am terrible at these internal pics) but this does seem different than the current one in the Wiki. This one has two leaf pieces where the wiki version seems to only have one. This also was fused together where the hole was at the bottom and was kinda difficult to pull apart. You can see some debris on both sides.

Note: the leads also unscrewed and looked like the leads in the Wiki so I didn't take a picture of those.

Switch internals and close ups are though to shoot, good work!

I see a face, two thumbs up and blowing a raspberry! Sorry, couldn't resist.

Thanks your switch internal photos. I got to see my switch later.
