You are right ! When I modified the program I wanted to put X=X MOD 8 to replace the conditions but I forgot to do so. However X AND 7 has the same effect and is better to put it directly in the bit calculation.

Great; I'm glad we got this sorted out! Thanks for updating the Wiki page.

The page for KUN COMPILER should have additional info..
Also for converted machines (MK PUBLIC) to have enable KUN COMPILER you do not have to use additional software.
My SONY 2 to 2+ has this option..
It is like SANYO, just use _BC and after that you can use _ (CALL) TURBOON and other instructions

@gdx: can you take a look at this page:
https://pikabu.ru/story/a_chto_vnutri_msx2_sanyo_2300_8612623 ?

According this Russian review, there's a 32kB MSX-AUDIO rom in this machine... It seems me strange...
Maybe it's actually the rom with the firmware for the LAN? And the 8kB ROM would be an incomplete dump?

Note: the SVI-709 ROM has been recently dumped, it's a 16kB ROM.

They also mention a DiskROM but there is no diskdrive and no Y8950.

They seemed to have used a Maxiol C2 and that of course has a DiskROM and an MSX-Music ROM (The FM-PAC ROM). I think they mistook those as being on board ROMs.

Putting the MSX-AUDIO and Disk-ROM Roms without a drive or Y8950 doesn't make sense in my opinion. sdsnatcher73 is probably right.

In addition, looking at the photo of the bottom board, pins 1 and 2 of the first two Roms and pin 1 of the third don't seem to be connected. So I deduce that there are 2 Roms of 16kB and one of 32kB. The wiki says that the 3 Roms contain the main-Rom, the sub-Rom and the communication-Rom (name I had found before for the firmware). Which is consistent with my guess but it's not 100% sure because even though it doesn't the case for Roms, it may have tracks on the other side.

I guess therefore that the content of the firmware ROM is probably repeated, what happens sometimes with 8kB software in a 16kB ROM.

@gdx: The last MSX released by Sanno (Sanno PHC-SPC) is not a Casio clone, but a Sanyo clone. I don't think the warning for Casio products can be applied on a Sanyo product.

I just added the remark for the Casio which was missing. Nothing prevented you from adding this exception.
