# How to Back Your Way Into Learning Z80 Assembly

A bunch of years ago, in the process of building timexsinclair.com, I added some disassemblies of the Timex/Sinclair 2068 ROMs to the site. I was never too happy with them because there were whole passages without comments.

A few years later, I added some new disassemblies, one by [Bob Orrfelt](http://localhost/indiv/bob-orrfelt/), the other by [Lloyd Dreger](http://localhost/indiv/lloyd-dreger/). Neither was perfect and both had some odd issues, but having them in hand led me to re-examine the 2068 disassemblies.
