Yep, so far there is not much things to do with it, but at least it works :)

I guess we could also probably try to find a way to draw nice window borders instead of + = and | :lol:

And yes, with 28 usable lines the Oric is definitively one of the machines that can display the most things.

You can also probably use #defines to do that, something like:

Code: Select all

 #define txy .byt $42

Loading and Saving from tape

I decided to reply to the post in Contiki http://forum.defence-force.org/viewtopic.php?t=29&highlight= here to keep it a bit more focused. Here are the (crapy) routines I used in my first demo (1997) and that I reused in ULA paint for loading and saving pictures... Basicaly it does the same thing th...

Re: XA and undocumented/illegal opcodes

I read the XA assembler doc, and to me, it doesn't support any illegal/undocumented 6502 opcodes. In the source code of XA is the following table: /* 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 imm */ { -1, 0x65,0x75,-1,0x172,0x61,0x71,0x469,0x6d,0x7d,0x79,-1, -1, -1, -1, -1, -1,0...

Re: Contiki on Oric Atmos?

From my experience with the VIC-20 port, it appears that about 40K of available RAM is the least required to get Contiki running with a basic window system and network support. Can Contiki works purely in a 40x28 characters video text mode ? If yes, then well that's easy, all the memory from $500 t...

Je rajoute que je n'est pas encore attaque la programmation du sons sur Oric, donc malheureusement cette demo est muette. Je pense que sur la prochaine il y auras du sons.

I guess we identified two main needs: 1) A more evolved operating system that would be closely compatible to something that exist on other machines in order to ease the communication between Oric and other machines (ex: MS-DOS compatibility to make it easy to read and write from a PC), while also ha...

It would be nice also that you indicate what are the characteristics of your disc system (Jasmin 1 or 2, single head or double head, 3" or 3.5" or 5.25", number of drives you have, etc...) This is why I voted "other", because "Microdisc connected to a Telestrat" seemed to refer to a 3" drive, but I...

Poll: Which is the storage system you do use ?

Ok, there's been some talkings recently about the representation of the various kind of oric hardware, and I guess it is kind of important to know who has what, and who uses what. Typicaly I would tend to say that a significative number of English people never cared about the Telestrat or Jasmin dri...

I guess we could say distinguish between ROM 1.0 and ROM 1.1.
Also for this to works, overlay memory has to be disabled, as well as additional eproms of disc drives.

Obviously, building a new (even mini-) OS is a big task. So I would suggest it should not only ease the task of developing demoes/games/applications, but also improve the transfers between the Oric and the other main platforms. I agree that being able to read on the oric something written on a PC, ...
