English version is just being translated from Hungarian, please be patient!

Introduction

The EP32 and the EP128emu Enterprise emulators exist for PC. EP32 is the work of Béla Vincze (Egzo) and can be run only in Windows operating systems. It has somehow more modest capabilities than EP128Emu but it is easy to configure and anyone can learn using it easily. It can be downloaded here: http://web.axelero.hu/egzo/ep/ep32-120.zip After downloading it doesn't need to be installed, it can be run at once.


Some essential information

After starting the emulator, first an emulated memory-test of some seconds can be seen (like in the real Enterprise computers) and an ENTERPRISE inscription appears flashing in different colours. You can go on by pressing any key and you enter the BASIC as default where basic commands can be given. You can read about these commands in the Enterprise Programming Guide (available here in PDF format: http://ep.homeserver.hu/PDF/Enterprise_Programming_Guide.pdf ).


Loading Enterprise programs into the emulator

Beginners mostly would like to try the programs downloaded from the net. The easiest way to do this is to emulate an Enterprise computer with a cassette tape recorder.


Emulation of a machine with a cassette tape recorder

In the beginning the programmes could be loaded into the Enterprise using a tape recorder, the floppy disk and drive spreaded only later. When emulating a machine with cassette tape recorder the emulator reads files from the hard drive of PC. To emulate a machine with cassette tape recorder you have to do the following:

1. Copy the program to be tried into a certain directory, with all its files of course. (Having downloaded a rar or zip file it has to be unpacked first.)

2. Using the emulator choose Hardware menu and load memory config then choose original EP with tape. (Thus you can emulate an Enterprise with a single cassette tape recorder.)

3. In the File menu choose Select directory for tape and point the directory where the desired files have beed copied previously into (see the first step here).

Attention! Putting the different files of the desired program into sub-directories within the chosen directory, the emulator cannot load the program!Copy all the files into this directory and don't create another directory within it with this purpose.


Thus if you give the START command (in BASIC) (or press 1 on numeric keyboard) after starting the emulator, a window will appear where you can select the file you want to load. When loading a game this file should be one with COM extension because it is either a stand-alone program or a loader which loads e.g. PRG, SCR files. These last mentioned file types cannot be run in themselves. (Do not be confused by the fact that PC DOS programs also have the extension COM.)

Besides the COM files you can directly load files with TRN (game with eternal life), BAS (basic programs) and EXT (system extension) extensions.


Emulating a machine with cassette tape recorder saving files is unfortunately not possible. So do not write programs this way because you cannot save them! Furthermore the programmes which run only with a machine with floppy drive do not work this way (there are only a few programs like that). If you want to save using the emulator (e.g. a basic program) you have to emulate a machine with floppy drive because the emulator cannot save files into the PC's hard drive (into "cassette tape"), files can be saved only to a floppy disk.

Emulation of a machine with a floppy drive

You have to have a floppy drive in your PC even if it is a more and more out-of-fashion device. To emulate a machine with a floppy drive you have to do the following:

1. Using the emulator choose Hardware menu and load memory config, then select any of the configurations differing from the original EP with tape (all of them emulate a machine with a floppy drive excepting this one).

2. In File menu at configure disk drives you can set, hogy a PC-s floppymeghajtó(k) mely Enterprise meghajtó(k)nak feleljen(ek) meg. Meghajtó helyett beállíthatunk floppy image fájlt, melynek használata gyorsabb, de erre sem tudunk menteni.

Ha lemezes gépet emulálunk, természetesen a használni kívánt program fájljait a lemezre kell előbb másolnunk. Fontos, hogy lemezes gép emulálásának megkezdése előtt zárjunk be minden olyan Windows-programot, ami a floppyt használhatja, még az Intézőben se legyen megnyitva a floppy! Csak ezután indítsuk el az emulátort! Ellenkező esetben az emulátor nem lesz hajlandó beolvasni a floppylemezről semmit.

Így elmentett fájljaink megjelennek a floppylemezen. Ha Windows Intézőből akarjuk megnézni, mit hozott létre a lemezen az emulátor, akkor előbb be kell zárnunk az emulátort, mert különben a Windows nem fogja megtalálni az új fájlt a lemezen. Az emulátor a lemezmeghajtót teljesen zárolja, így közben ahhoz más programmal nem férhetünk hozzá.


A floppy használatáról bővebben az Enterprise EXDOS felhasználói kézikönyvben olvashatunk.


Using a floppy image

Floppy image készítéséhez a DOS alatt működő CPDRead programra van szükségünk (Innen letölthető).

Az emulátorban a File menüben a configure disk drives menüpontot választva beállíthatjuk, hogy milyen betűjelű meghajtóként szeretnénk az image fájlt használni. A drive a:, drive b:, drive c:, drive d: valamelyike alatt jelöljük be az use disk image-t, és az insert gombbal keressünk rá az elmentett image fájlra! A remove gombbal eltávolíthatjuk virtuális meghajtónkból az image fájlt.

Ismét megjegyeznénk, hogy ha floppy image fájlt használunk, nincs lehetőségünk elmenteni az emulátorral a fájlokon végzett módosításainkat az image fájlba.
