Help ascertaining Megadrive board version

[PeterWar]

Hello,

I have the possibility to buy a perfect condition asian Mega Drive MODEL No.: HA-2510 withe Serial No. A20862961 Made in Japan. This particular console has an EXT port but
it has no AV Intelligent Terminal/High Grade Multipurpose Use engraving.

Do you think it has TMSS? what board VA version would it have?

Thanks in advance for your feedback.

That sounds like it could be a VA6 or VA6.8 model which would most definitely have TMSS. There is the slight possibility it could be a VA7 since the Japanese/Asian version of the VA7 board retained the EXT port.
