Royal / Triumph-Adler Alphatronic PC

This is probably one of the more unusual machines of my collection. According to Old Computers, Triumph-Adler was the merger company of the 2 typewriter manufacturers which later merged with yet another American typewriter company named Royal. The company produced a few computers with limited success and the Alphatronic was apparently their play into the home computer market. According to what I read it mostly sold in Europe (you can sometimes find some Alphatronics for sale on eBay Germany) but it was actually manufactured in Japan.

I picked up this machine and its original amber mono monitor for a bargain. I was really expecting a non-working computer but amazingly everything worked perfectly! I just had to clean it (quite a bit) and at the end the computer and monitor are in excellent shape. Basic loads from ROM and as you can see it works just fine:

The one part missing on this setup is the disk drive. The computer does have a cassette output connector but the pinout is not compatible with any cable I have. Info about this computer is extremelly scarce so if you have any please let me know!

    Great post! These were the machines we used in computer class at Yarmouk University Model School in Irbid, Jordan (GE: 32°31’59.74″N 35°51’17.73″E), where I went to prep and high school ca. 1984. The displays weren’t amber, though; they were white on black. IIRC, the versions we used had 16kb ROM, if there was ever such a version, and only the teacher’s machine had 32kb. Then the school set up a new, bigger lab after a third floor was added to the building ca. 1985, and the old TAs were all replaced with NSX-based Sakhr machines that were assembled in Kuwait!

    Sorry about the typo… that is, MSX.
