Earl,

I see that there are some different ranking systems. I use the BT2630 test and
if i take into account the mentioned scores you gave :
>1) Tasc R30 King 2.2 with a mean rating of 2498
>2) Mephisto Genius 68030 with a mean rating of 2476
>3) Meph. Risc 2 (1 Meg) with a mean rating of 2471
>4) Mephisto Vanc.(36 MHz) 68030 with a mean rating of 2453 also a (CRA) game
>   in 30 min. 2491
>5) Meph Lyon 68030 with a mean rating of 2453
>6) M.Berlin Pro 68020 with a mean rating of 2443

I would calculate my modul at 2661 based on a average conversion factor from the
given machines.

The BT2630 test give
>1) Tasc R30 King 2.2 with a mean rating of 2306
>2) Mephisto Genius 68030 with a mean rating of 2227
>3) Meph. Risc 2 (1 Meg) with a mean rating of 2203
>6) M.Berlin Pro 68020 with a mean rating of 2255

My modul performs 2433 on this test.

Greetings,

Ruud
