After many more cycles on my Nexus One, Group D has just finished a complete thirty seconds-per-move tournament in Chess for Android , played from both sides of all positions in the Nunn opening suite under the conditions described earlier. Quite a shuffle-up in the results this time compared to the qualification tournament. Congratulations to Aaron Becker for Daydreamer's promotion to Group C.

The Micro-KIM arrived today! I did some initial experimentation with my 6502 cross-assembler and was happy that the paper tape format l recently added could be uploaded to the device without any problems. What better first program to write than "HELLO WORLD" (except only HELLO fits on the display)? It was fun figuring out how to control the display using low level 6502 programming.

I have extended my cross-assembler with a built-in disassembler that can directly read from paper tape format (and a few other formats). For example, the following test assembly program       .org $0200       ldx #100 loop  dex       bne loop       brk is, under option -P, assembled into paper tape format (text representation): ;060200A264CAD0FD0003A5 ;0000010001 Option -dP activates the disassembler on paper tape format represented as text, which disassembles the format above back to: $0200 a2 64  ldx #$64 $0202 ca     dex $0203 d0 fd  bne $0202 $0205 00     brk
