Update Content 23/7, 6502 Assembly

This morning, before I left my home, I had updated Register Transfer Operations session of the 6502 instruction set manual.

There are totally six commands have been updated:

  1. TAX
  2. TAY
  3. TXA
  4. TYA
  5. TSX
  6. TXS

I have found out and removed some strange links generated from google site.  These were caused by links consisting different fonts setting.  That’s why some strange page have been found from google search on my website. Another problem is that, when I use IE 8 to edition the 6502 website, I found I cannot scroll down when I have click the view HTML button in the google site interface.  So, I had to edit the page using Firefox this morning.

Happy Programming,
