- Euphoric is an Oric1/Atmos emulator. This version is not a definitive one,
- but it is good enough to be widely distributed and it will surely make Oric
- enthusiasts feel a lot of nostalgia, and I hope it will be a favorable factor
- for them to meet again.
-
- The up-to-date version will always be on a web server, URL :
- http://www.ensica.fr/LOCAL/ORIC/euphoric.html
- There you will also find the latest information, tools and programs for the
- Oric.
-
- Euphoric runs on PCs only for now, but you can chose between DOS and Linux.
- The DOS version is expected to be soon fully DPMI compatible and runnable
- under the DOS boxes of Windows 3.1, OS/2, and Windows NT 3.5.
- A multi-platform Unix version is also in stage, thanks to O.Balet's help.
-
- Before asking any question, you must be aware that you need an Oric rom image
- to run euphoric. So, you must be a real Oric user to use euphoric; you can
- read your oric rom with an eprom programmer, use a tape transfer utility, a
- parallel link utility, or delegate me this task through the web server if you
- don't want to open your box or risk the life of your Oric.

- Questions and Answers
-
- Q1: How to contact me and get some help, or just tell me a program works or
- does not work...
- Q2: It doesn't work : I get "svgalib: Cannot get I/O permissions"
- Q3: It doesn't work : I get "Not running in graphics-capable virtual console"
- Q4: It doesn't work : I get "Oric.ROM not found"
- Q5: I used readtape to get my ROM : it is more than 16384 bytes...
- Q6: CLOAD doesn't work...
- Q7: I've got multi-part programs or protected programs...
- Q8: My protected program doesn't load, help!
- Q9: My program loads but then the emulator crashes...
- Q10: How to quit Euphoric ?
-
- R1: Send me a mail at frances@ensica.fr
-
- R2: Euphoric needs the right to access VGA physical IO ports. It uses some
- routines of the svgalib library. As every other application using svgalib,
- the program must be 'setuid root'. Become root, verify that root owns the
- program and set the setuid bit ("chmod u+s euphoric") then quit super-user
- mode, you should start the emulator.
-
- R3: Euphoric uses svgalib. This library allows to develop graphical applications
- while not using X-Window. It doesn't work under X11 (it doesn't have to), you
- must start the emulator under a virtual console.
-
- R4: Euphoric reads a ROM from the file Oric.ROM (Unix users, take note of the
- case) in the current directory. You can use an Oric 1 rom, an Atmos rom, or
- every rom you write. If an Oric 1 or Atmos rom is detected (address of the reset
- vector), it will be patched accordingly to allow tape commands.
-
- R5: You need to get rid of the file header. If you saved the ROM on tape without
- a name (ie. CSAVE "",A#C000,E#FFFF), it should be 16398 bytes. Just use the
- unix command :
- dd if=oric.old of=Oric.ROM bs=1 skip=14
- If you are a DOS user, load the file with debug, then :
- -R CX
- 4000
- -W10E
- -Q
-
- R6: The name you specify in a CLOAD command is taken without modification under
- the host operating system. With Unix, lowercase et uppercase is meaningfull,
- so if you ask for CLOAD "MYPROG", uppercase name MYPROG has to be a file name
- in current directory. You can use a path with CLOAD, eg. CLOAD"FILES/MYPROG"
- with Unix or CLOAD"D:\FILES\MYPROG" with Dos, but be careful since the Oric
- cuts the file name and keeps only 16 character.
-
- R7: readtape reads only the first file found in the wave file. When recording,
- sample each program in a different file, or cut the file with your graphical
- utility (find the pauses). Rename the files with the original name found by
- readtape, if needed. If it doesn't work, it might be that a multi-part program
- don't use names since the tape is sequential. If you cannot hack into the
- program to introduce names, use the following : concatenate the parts in a file
- named "Tape" (note the uppercase under unix). Under the emulator, just use
- CLOAD"" (the "Tape" file will be used for the first loading omitting the file
- name, and for every next loading, without "rewinding" the file). Just use cat
- under Unix to catenate files. With Dos, use the command :
- COPY FILE1+FILE2+...+FILEN /B TAPE
-
- R8: The format chosen for programs should accomodate the most used protections
- (change of the header during loading, different synchro characters, etc). The
- "Tape" file will evolve in next versions to a bit file very close to the
- contents of the tape, without a strong penalty in file size (13 bits for 8).
- If it is not enough, I will introduce another format keeping track of the
- length of bits.
-
- R9: There is still missing code in this emulator, I need to complete my VIA
- emulation, eg. the two timers keep running at 100 Hz. I need to emulate
- undocumented opcodes, too, some programs may use them. Send me your program
- so I could diagnose the problem. If a program works, tell me too, I will
- maintain a list of good/partial/bad compatibility.
-
- R10: Key F10 exits the emulator cleanly. I currently have a problem under Linux
- with key Ctrl-C since svgalib gets it before me, and exits the emulator.
