Re: Are there any english Oric mags left?

Where is Scotland are you from? There used to be a West Lothian User Group. (Long since folded.) I'm currently in Elgin (north Scotland), but I'm originally from the south of England. I was in Devon when I first bought an Atmos. Oric User Monthly was the longest running UK magazine. There were a fe...

Simple multiplication

Just checking I have understood things. I have written, what I hope is a simple multiplication routine to multiply 2 bytes, returning a word. This could obviously be very useful for calculating screen addresses. Just want to check that what I have come up with is as efficient as possible, so I would...

The bird is the only one I could really think of.

Did Oric ever have a mascot?

I was thinking about this today, and I can't seem to think of a single character, from a game, that could possibly be described as a mascot for the Oric. On the Spectrum, there was, at first, Hungry Horace, then they had Miner Willy, followed by Sabre Man, and finally Egghead... each of which could ...

Are there any english Oric mags left?

Title says it all really.

Is anyone still producing anything (printed or electronic) for the Oric?

Re: Creating Oric software on OS X

No need to be optimizing the number of messages. It's not like you were spaming crap on all the forum :) As long as it's interesting and does not propagate false information it's good to have that on the forum, if only because it will later appear in the google results if somebody is searching for ...

Re: Creating Oric software on OS X

Last post on this subject...honestly :-) By using an include and some very simple conditional compiling, I have now worked out a way to make it even simpler: I have an include file called "header.s" : //Header .byt $16,$16,$16,$24,$00,$00,$80 #ifdef AUTOSTART .byt $c7 #else .byt $00 #endif .byt >_fi...

Re: Creating Oric software on OS X

Just to expand on what you said DBug, I have had a little play and come up with this: //Header .byt $16,$16,$16,$24,$00,$00,$80 .byt $00 // $80=BASIC Autostart $C7=Assembly autostart .byt >finish,<finish,>start,<start,$00 //Program name .asc "TEST" .byt $00 *=$400 start lda #65 sta $a101 rts finish ...

Re: Creating Oric software on OS X

I feel like an idiot. Can't believe I didn't think of that myself.

What I can also do is write a quick and dirty console app for OS X that will attach the header for me, including the End Address which can be easily calculated.

Thank you DBug, you are a star!

Re: Creating Oric software on OS X

Ok, time to show my complete ignorance of things assembly. I have a very simple program: *=$400 lda $65 sta $a101 rts I use the following command for XA xa -o orictest.o orictest.asm A hex dump of the resulting binary is: 0000: A5 65 8D 01 A1 60 I understand that this is exactly the assembled code, ...

Re: Creating Oric software on OS X

You'll have to excuse my ignorance. But, am I right in thinking that, for a single source file project, alI need to do is call

Code: Select all

xa source
or

Code: Select all

xa -o ouput source
to create an executable that I can then convert to a TAP file to load into the Oric emulator?

Re: Creating Oric software on OS X

Take a look at the OSDK in http://osdk.defence-force.org/ . In the "bin/make.bat" file is the list of all tools being called to build an Oric program, including the XA parameters. The source code of the OSDK components is available on the SVN server: http://miniserve.defence-force.org/svn/public/pc...

Creating Oric software on OS X

I've been teaching myself 6502 assembly, using an Atari 800XL emulator, but I would also like to do some dev for Oric. I am using OS X and have recompiled ATASM and MADS for my Atari development, but I would like to know which cross assembler people here would recommend for developing software for t...

Re: 2013 - Oric is 30 years old!

After using my fathers Spectrum, I bought my Oric Atmos in early 1985 (I think). It definitely opened up a new world to me.
Since then, I have gone through Atari 8-bits, Atari ST, PC and Mac, but it was the Atmos that really gave me the programming bug.
