Epson HC-20 / HX-20 - Scans of Japanese magazines?

[Martin Hepperle]

Recently, I learned that there were a few issuses of a Japanese Magazine "Oh!HC" which was obviously promoted by Epson.

Unfortunately I was not able to find any scans of these issues.

Do we have some Japanese readers in this Forum who could provide links or scans of these issues?

Even if we cannot read the Japanese text, translation machines help and BASIC and assembler programs are an international language.

One of the cover images I found looks very promising

Ouf... Sorry for not being helpful. I have just now learned of the existence of this book. I think this book is very rare in Japan, never seen it in auctions...

I presume you have already asked the curator of the online museums that show issues for further leads.

Dentaku museum has an image of 5 issues stacked together.

I tried to obtain scans of these books but was not successful.
People in Japan seem to honor Copyright more than people in other parts of the world.
Legally this is fine and honorable, but causes such material, which has low or zero commercial value today, to vanish forever.

I did not try to contact the Dentaku museum.

I thought that maybe someone living in Japan and using local internet forums might have a better chance to obtain copies or scans of such material.
For me, the only source of a few HX-20 related programs (including mixed machine language/BASIC programs) was the I/O Magazine, which can partially be found on archive.org.
The focus of this magazine lies on Japanese systems like FM-8, PC-6001, MZ-80B, PC-8001 and articles for the HX-20 only appears in three or four issues, though.

A few additional pictures of the last issues of the Oh!HC magazine - unfortunately only pictures from the internet.
Maybe someone from Japan wants to have a look...
