This disc contains Z80 source code for a number of well-known programs, for apprentice programmers to study and learn from.
All of the files are in Protext format and were written for Arnor's excellent Maxam 1.5 assembler. You won't be able to use them with Turbo Assembler (at least, not the current version), so don't bother trying.
Although the source code is not intended to be reused verbatim or reassembled - indeed, some programs (such as the BTL 3 intro and PowerSpell) require additional resources before they will work properly - you are welcome to write for permission should you find a routine you can't live without. Side B of the disc also contains several subroutines that you are free to use in your own programs.
Standard "Almost PD" conditions apply to all software on this disc: it may not be distributed commercially or semi-commercially without written permission from the author, and although you are welcome to copy it on an individual basis, you should copy the whole disc rather than just individual files.
Happy hacking!
