The Philips models with NEC marked PCB's are from Kyocera.

Where does this information come from?

Don't know if Kyocera third-partied only the PCBs manufacture or the all assembly to NEC.

If the boards are branded NEC and sold in Philips machines, it could only have been Philips who ordered them from NEC. I don't see what Kyocera would do there. By cons maybe Kyocera would have assembled the rest but we need proof to confirm it.

The fact that the PCBs have NEC printed on them would in my view mean that they were designed by NEC, not just made-by.

Possible but the only confirmed MSX produced by Kyocera is the Yashica YC-64.

ヤシカの事業を引き継いだ京セラ光学機器事業本部は合併後も高級機のコンタックス、低価格機のヤシカの各ブランドでカメラ生産を続けていたが、国内向けの普及機については1986年発売開始のオートフォーカスコンパクトカメラ「京セラTD」から京セラブランドで生産を開始した。しかし海外市場を重視した旧ヤシカの戦略で海外における「YASHICA」ブランドの知名度が高かったため、海外向けの低価格機は引き続きヤシカブランドで販売された。また合併翌年の1984年にはヤシカブランドの京セラ製MSXコンピュータ「YC-64(オランダ語版)」が海外向けに発売された。

It is even indicated under the machine.

Even if there are some similarities Yashica PCB does not have the white squares around most of the components like those of Philips 8020, 8220, 8230, 8235, 8245.

I think several Japanese manufacturers have participated in the manufacturing of these philips models (Mitsubishi for the power supply, Mitsumi for the video board, then maybe Kyocera, Nec and probably more because some mainboards are very different).

You are right, there is no NEC logo inside the YC!

I think you must be getting old (just kidding you know), but have a look at that big chip that forms a T together with the Z80 Wink

But it is uncanny how similar that YC64 looks to the VG8020, sisters for sure...

Perhaps Kyocera sold a part of its business to NEC, which included the MSX... That would explain why later Philips PCB's have the NEC logo.

Looking around, I actually found a news release from 2013 that Kyocera acquires 100% of Shares in NEC Toppan Circuit Solutions. This is too new since it was established in 2002, but perhaps they had something earlier already. In any case it lists Japanese factories in Niigata and Toyama.

Looking further, I find that "NEC Toppan Circuit Solutions" was established in 2002 by both NEC and Toppan,

About MSX-DOS and the Japanese Sony HB-F500. Let me just repeat myself as what I wrote on the Wiki has been reworded to mean something else. The HB-F500 according to my research shipped with ONE disk, 漢字MEMO (Kanji MEMO). This disk does NOT contain MSX-DOS. There is no second disk.

The Kanji Memo disk contains various other small apps like a calculator, clock, calendar, etc.

I checked all Japanese MSX Magazines of the era and there is even a review of 漢字MEMO in issue 1986-02 on page 186. There is no MSX-DOS included, at least not with the original revision. And I don't think they changed it for the 2nd revision either, or at least there is no evidence for it.

Check other applications provided on system disk, like Video Graphics, they run under MSX-DOS 1 (included on the disk). So deleting what I've added is simply stupid, as I don't speak about an non-existing second disk.

For those who want to know which text has been deleted, here it is:

"Note about the Japanese Sony HB-F500 computer: MSX-DOS 1 does not seem to have been provided with this computer on an apart disk, but probably the application disk includes it (as most system disks provided with MSX computers actually run under MSX-DOS 1). Of course, it needs to be checked.'

All the words have their importance, especially 'probably' and 'Of course, it needs to be checked."

Who was speaking about deleting without trying to understand? I leave the other MRC users the role to appreciate this deletion.

There was NO second disk, there was NO video graphics included with the Japanese HB-F500.

There were 2 different programs named video graphics, one included with the NMS 8280
https://www.generation-msx.nl/software/a-koene/video-graphic...

And the other published by National
https://www.generation-msx.nl/software/matsushita-electric-i...

If Sony would have included a graphics program it would have been something like Halos
https://www.generation-msx.nl/software/hal-laboratory/graphi...
Which was included with the later HB-F700 models.

And all your doing is speculating. While I have actually checked the magazines of the era.

Show in my text where I am speaking of a second disk! A real challenge for you!

Show in my text where I say that Sony has added a video graphic progam. Another real challenge for you!

You don't have even checked the files of the Philips Video Graphis disk. The two first files are MSX-DOS 1!

Why would it not possible for the Sony HB-F500 application disk? Of course, we need a dump of this disk, but I say that precisely at the end of my text.

You read selectively and in your head, my text is so different from what I've written!
