what may be two firsts...

Post by MikeB »

We now have 6 man syzygy tablebases loaded on a DGT-PI chess computer ( using a 256 GB micro SD card) and my friend Alan Cooper has a working copy of Leela Chess Zero working on a DGI-Pi Chess computer. The DGT-PI chess computer can be hooked up to either a DGT eboard or DGT smart board or to a Revelation board.

Some terminal commands (Note: McBrain has special non UCI shortcut commands in addition to the UCI commands):

Code: Select all

xx@PicoChess:/opt/picochess/tablebases/syzygy $ du -sh /opt/picochess/tablebases/syzygy
151G    /opt/picochess/tablebases/syzygy
xx@PicoChess:/opt/picochess/engines/armv7l $ ./McBrain-92

info string Found 510 tablebases

Hi Michael,

.... or should that say ‘what may be three firsts...’

With your McBrain Engine also on our DGT Pi’s.

LCZero is an intriguing prospect for a future Picochess / DGT Pi Engine though.

I’m glad I can help ..

Yes indeed , we have three firsts - all of which are directly attributable to Al’s expert help and guidance . I can also confirm that , with the expert guidance from Al, I also have the Leela Zero chess engine working on the DGT-Pi.
