The Z88 Development Team reverse-engineered the V4.0 ROM into source code in 2003 and has since then done substantial re-organisation and optimisation of the existing OZ code base, now fulfilled many of the original end-user wishes expressed in the independent end-user "Z88 EPROM" publishing made available in the early nineties.
Per Svensson - a dedicated Z88 user - did all the OCR scanning of the printed 4th edition and converted it to HTML. With his permission, we continued the process, replaced all screenshots with live snapshot from the Z88 emulator and finally converted it all into this wiki.
