Hi Artrag,
One question, I´ve been playing Uridium in TrSt, 8245, Mitsubishi ML-G1, 8250, Hb-F9 and the game works fine.
But this morning I wanted to play in my Sony HB-20P and the cartridge reboot constantly the computer.

On other web-site they said it have only 32K.

To be sure, switch on your HB20 and let go to Basic. If Basic Memory is 28800 bytes free it's a 64K computer.

The MSX of 32KB display too 28800 bytes free.

HB-20P has 64KB in Slot 3.

Heya.

An HB-20P double user here. Yeh, I have a pair of them. Both with 64ks of RAM. As it says at its own manual. That's why it can load cassette games that required 64ks.
64ks is also the amount of RAM it will show if you perform a RAM Search routine properly. 64Ks as it can load MSX-DOS. Then, again, from DOS you can easily see/check that you have RAM on page0, on page1, on page2 and on page3.

I think I can't be more clear Big smile The only proof left is to open it and take pics from the RAM IC's. Maybe you can see something on those pics (I can't!) http://old8bits.blogspot.com.es/2010/04/comenzando-con-dos-h...

And yeh, my two 20P have the almighty Toshiba VDP :P
