You speak :
We need you to add flags !
Contribute to the Oric Project, choose a project and join its development !
Cross-developments tools (the lcc compiler and the cross-assembler) have been
moved to the Euphoric page.
The Oric Project : we want you !
Here you will find some developments in progress : if you are interested in
contributing to one (or several) of them, use the form below.
The list is not exhaustive and you may enter with your own project, let us know
your intentions !
Ok, a progress indicator now :
Yeah, it has been done since the starting of this page !
It's a work in progress, and it should be GREAT !
Too bad, an Oric fanatic took it, you should have been faster !
[none] Mr. X shall start it tomorrow !
SEDORIC 3 !
A great work from André Chéramy ! Sedoric 3 is compatible with both versions 1
and 2 (which were mutually incompatible when using machine code programs
accessing system calls), new commands available, and all known v1&2 bugs fixed !
Sedoric 3 is THE OS to use on Atmos/Microdisc !
SEDORIC has evolved to handle 80 tracks disks. What about a new hierarchical
file system and unformatted files ?
Sedoric has been improved from Fabrice Broche's 1.0 version to 2.1 by Ray McLaughlin,
and is currently 3.0 thanks to André Chéramy.
Files in Sedoric are always formatted (i.e typed) files: each element is either
an integer, a real, or a string. This is very useful when building database
applications, but very annoying when building system tools (archivers, compress,
editing ascii files...). Maybe it's just a matter of re-using some low-level
routines of sedoric, but adding unformatted files (streams of bytes or chars)
would be great !
IEEE floating-point routines for the lcc65 ANSI C compiler !
Ok, I've done a first release with single precision
Standard input/output routines interfaced to Sedoric for the C library !
Vaggelis Blathras and Alexios Chouchoulas have already
written many routines for Oric graphics and sound, and even a first interface to
We need someone knowing well the internals of Sedoric to provide standard C
A linker for lcc65 !
Now you may develop separated objects with the lcc65
compiler, and link them with libraries with Vaggelis' linker. Your executable
will only include the needed libraries, and it's easy to mix C and assembly
You may also engage in a new port of lcc65 with 8 bits integers,
leading to the fastest language on Oric platforms (except machine code) !
I have developed a new back end for the 6502
(with 16 bits integers), following the lcc's code generation interface (I have
not finished to implement floating point, though).
It is much better than the previous one (emulating a 32 bits VAX with a 6502 is not
the fastest thing...).
If you want to produce the fastest code, really designed for the 8-bit 6502
processor (it needs modifications in lcc's front end this time), quick ! or I
will put a here ! Miam... ;-)
When the above standard input/output routines will be available, it will be
time for the first NATIVE C compiler on Oric platforms !
You can start it now, it's a problem of clever splitting the code to have each
part fit in oric's 48k ram. As above, contact me for the source.
For the FUN, you may then be interested by a port of a Mini-Unix !
Andy Tannenbaum made Minix' kernel fit in less than 64k.
Xinu from Douglas Comer was about 4K in its first release.
And there's also a 6502 multitasking OS documented in Peter's hardware page.
What about a real-time micro-kernel ?
It's not a joke, there are commercial micro-kernels running in 4 K ! The oric
may be used as an embedded system : it has IO ports, timers, interrupts, and
even keyboard and display ! So, what are you waiting for ?
OricLisp released !
Not really a new project, I wrote it in 1986... but
the manual came in 1995 ! Try it in the archive page, enjoy recursivity, and
build problem solvers easy !
Oric terminal on the Internet !
Connect to a Unix, VMS, OS/2,... workstation with
your Oric and communicate ! Thanks to Vaggelis Blathras' incredible color VT100
emulator featuring 80 columns, you can use your Oric to read and send mail or
news, or talk to someone else, or whatever you enjoy !!
Oric really ON the Internet !
Take it today or tomorrow will be too late ! Porting a SLIP (Serial Line
Internet Protocol) or PPP package along with a TCP/IP stack will launch the Oric
in the 3rd millenium !
You need an RS232 interface ? It's available, ask for it on the oric list !
You think it's impossible ? You're wrong, just do it and you will have the
Animation, Sound, Games, Educational software
First link game !
Challenge a friend over a modem link and play
Tea for Two Blitz Chess ! Will your brain be fast enough ?
You can chat and play with your friend at the same time !
And the C source is given with the C compiler package.
An 8-bit computer without new games is a dead computer !
Let other people enjoy your creations ! Oric is not an obsolete machine for
games ! Have you seen the games running on a 120 MHz Windows machine ? Board
games, very few animations... you can do at least the same things, surely better !
What about adventure games ? Very few people still use tapes, it seems quite
masochist now. Today's oric users use a disk drive (if you don't have one and
are interested in, you should know that you can buy a controler for a standard
(PC) 3"1/2 disk drives at about $80).
So what about a multi-file adventure game running with Sedoric,
do you think 680 K will be sufficient, or do you want to make a multi-disks
program ? We are waiting for your own King Quest series...
Or you lack THE idea making your game a Hit ? Not a problem, what about
porting one of the best Apple II or C64 program ?
Start a new generation of flicker-free arcade games!
Have you seen Jonathan Bristow's new game ? "Magnetix" specifications (parallax
scrolling on 75% of the screen, sonix music...) prove that you can push the
limits ! (Magnetix is available through OUM).
Have you tried the small routine below ?
It changes the background color from
red to green and green to red, BUT, it is synchronized with your TV, and you
can see this materialized !
Enter the program on a real Oric1 or Atmos (it should work on the
TeleStrat too), but not on an emulator. Save it on tape or disk, then RUN.
Use F key to raise the frequency of the timer, S key to slow it down, and Q to
It brings the detail Oric missed : an interrupt signaling the vertical screen
retrace. So, think about what you can do with a 50 frames/s
animation, or a double-buffered technique...
Just add a small routine like this one in your program asking the user to
graphically calibrate the timer at the top or bottom of the screen, and you
will never seen again those flickering sprites !
The Atari ST has the sound generator of the Oric !
Do you think it has been used at its maximum on the Oric ? Have you ever seen
a soundtracker on your favorite computer, a MODule player ?
I would love to do it, but there are so many other things...
Oops, have a look at Sonix from Jonathan
Bristow ! (available from OUM)
Design the second Oric generation !
Wouldn't it be nice to design a new Oric computer, upward compatible ?
Of course, there's no hope to compete with the PC standard, so what about a single
ISA card (or PCI) featuring a 65816 processor (not so updated, it is used in
some consoles, like Atari's portable one), you would have an Oric card in
your PC, sharing the display and the keyboard !
We could first write a software simulator of this, and then, why not, build
a real one !
If you have some skills in this domain, you're welcome !
