It's an M8192-YB.
That one should be OK. Sorry, there was a typo in my post; I should
have written -YB not -YA. -YC is a -YB with an accelerator factory-fitted.
There is a 40-pin
socket on the board though, that I am given to understand is for the
accelerator.
All the M8192 boards have that; it doesn't necessarily mean it works :-)
