MYZ80 - READ.1ST MYZ80 is a Z80 emulator package for IBM AT (and better) computers. It creates a virtual Z80 computer on which you can run CP/M 2.2, CP/M 3.0 and other Z80 programs. It is a high performance emulator giving great speed, reliability and compatibility to your Z80 and CP/M programs. Read MYZ80.DOC for more detailed information. This archive contains the demonstration version of the MYZ80 package. You MUST read all of the following before using any part of this package. The files in this package are copyright Simeon Cran 1991,1992,1993 but are being distributed to demonstrate the MYZ80 package. You are hereby provided with a LIMITED LICENCE to use the MYZ80 package. Details of the limitations are provided in this document. The files supplied are: myz80.doc ....quick documentation for MYZ80. cpm.exe ......the MYZ80 program file. boot.cpm .....a boot file containg a CP/M compatible system. a.dsk ........an example disk file containing the MYZ80 utilities. history.txt ..information regarding the modification history of MYZ80. install.not ..how to install over an earlier version of MYZ80. read.1st .....the file you are now reading. order.frm ....an easy order form to help you to register MYZ80. MYZ80, as supplied here, is fully functional. The only functional differences between the demonstration version and the registered version (as of this release) are extra screens of information which slow down the booting process somewhat and require keypresses after a delay of two seconds to clear them. This is done to encourage you to register the software. When you do register, it is likely that improvements will have been made to MYZ80, and you will receive an improved version of the program. Registration does not get you a printed manual. The registration fee is so small that this would not be economical. Besides this, the program is very simple to operate, and the MYZ80 utilities have online help messages. Registered users may request information about MYZ80 which is not provided with the package. Requests of this sort made by unregistered users will be ignored unless it is considered that the information would be generally of use to registered users as well. Registered users will also be given priority when it comes to sorting out any problems they might be having in adapting MYZ80 to their needs. Registered users will receive one free upgrade from the version that they receive when they initially register. The registered user can request this whenever they feel the upgrade is worthwhile. This policy does not allow for major upgrades (e.g. version 1.xx to version 2.xx would require re- registration, however version 1.05 to version 1.90 is allowable as the free upgrade). Upgrades beyond the first free upgrade but not including major upgrades are available for $10. With regard to the suitability of the MYZ80 package to any purpose, no guarantees are being made. Every reasonable effort will be made to assist registered users in getting the most from this package, but no guarantees are being made nor implied. If you are going to use MYZ80 for profit, you MUST register it first. What constitutes the use of MYZ80 for profit? Any use of the program which brings direct or indirect economic returns to you. This includes the following uses (and may include others): Using MYZ80 in any way to develop software. Using MYZ80 to demonstrate other software or a computer system. Using MYZ80 to run software which is being used for business purposes. Using MYZ80 as a teaching tool. The demonstration version of the MYZ80 package exists to demonstrate what the registered version is capable of, not to help you make a living. If in doubt, register. If you fail to do so and breach the limitations of this LIMITED LICENCE you may have legal action brought against you. Any use of the MYZ80 package which may directly or indirectly further any war effort or which directly or indirectly promotes or assists the cause of capital punishment or any specific capital punishment, is a breach of the LIMITED LICENCE. This includes (amongst other things) using MYZ80 to run an editor program to write a pro-war or pro-capital punishment letter. The MYZ80 package must not be used to destroy humanity. You are hereby given the right to make multiple copies of this demonstration version of the MYZ80 package as long as the package remains complete. For convenience, the form of the archive (.ZIP, .ARJ, .LZH etc) may be changed as long as the contents are not changed and are all included. Phew!.... but you get the idea: I'm not about to just throw away the thousands of hours of work that have gone into creating MYZ80. MYZ80 is the BEST Z80 and CP/M emulator for IBM AT (and better) compatible computers, or at least I think so. If you don't agree, you are free to remove its code from your disks. If however you do agree (and I think you will), then please register and become part of the growing community of happy MYZ80 users who are keeping CP/M and Z80 code alive.
