Black bishop on white square graphics error #6

The code you have is .BYTE 80,0A0,00,80 ; Black Bishop on White square The 00 should be 80 (I checked against a scan of the book).

The book also has an least one error!

You may also wish to compare against the disassembled TRS-80 version, I used it as my standard.

Thanks for your efforts (also phillipeaton for his awesome work in particular). I was concentrating on getting move generation and just did enough with the graphics and user interface to get it to assemble, no more. I have an open project that I haven't published on github yet where I polish up the Z80 code with a view to running it on a vanilla CP/M emulation with ASCII graphics. I will tidy this issue up when I get back into that work sometime early in 2022.
