Topic: Belarussian БАЙТ (BYTE) & DivMMC

Hello,

I am trying to get DivMMC to work on the Байт (Byte) clone of the ZX Spectrum.  I've designed a converter board to convert the BYTE's 96-pin Soviet-era expansion connector (СНП59-96) to a Speccy's usual edge connector.

With some additional patching, it is *almost* working.  The BYTE has two modes - one is supposedly "ZX Spectrum compatibility" - so this is the one I'm trying. 

It tries to boot but fails with:

Loading ESXDOS.SYS...   [ERROR]

ESXDOS.SYS error

I have freshly formatted a 16GB SDHC card using the official SD Formatter (I'm using a Mac) and copied contents of 0.8.8 release across.

Any suggestion?

Thanks, Brett.

Нужно смотреть в сторону тактирования. Я ставил кварцевый генератор на 4mhz.

Can this Belarussian Clone run with original Sinclair 48k ROM?
