Standard ROM MSX2+ from BlueMSX package does not work on this computer. Works well ROM from Sony F1-XV.

Probably because the F4 device is different (Normal on Sony MSX2+, Inverted on boosted MSX2+, actually based on Panasonic machines).

Maybe useful for someone transplanting Russian key layout into the new ROM: Russian key matrix

As I have created the msxsyssrc project I will be able to create a rom for
any country lay-out. @DJs3000: I assume you do not have option rom adresspace as you are upgrading an msx2? 2

zeilemaker54 I do not understand the question Smile
Rework the text to make it easier. Do you want to know all the details of the upgrade?

PS. I use a translator (English-Russian).

This MSX2 was made in Japan for Soviet school. In Russia, these machines sold a lot for the price $ 67-97 depending on the state. I do not sell, I collect Smile you can contact one of the many people who sell. For example in this topic.
