Yes, but it's still a useful dump to examine the initial RAM contents.

So, what is the serial number of this Sony HB-F700S?

Some notes:
- the BASIC/BIOS ROM can also be found in the HB-F9S
- the sub ROM can also be found in the Spanish Mitsubishi ML-G1 and G3.
- the disk ROM can also be found in the Sony HB-F700P

I believe you have a memory mapper in slot 3-3 not a ROM Wink

If the HB-F700S has one internally yes, but not an external one Wink

With this, the OpenMSX team could already emulate the HB-F700S? Thus the XML would be available to use the machine with the emulator.

Is the HB-F700S keyboard matrix known?

Hi gdx, I executed KEYMATR.BAS and posted the result of pressing SHIFT+GRAPH+0 and the Key "1" in the numeric keyboard. If you need something else let me know Tongue

This method seems insufficient to me to know precisely the matrix.
