Re: Need help fixing Oric 1

I suspect I can hack the ROM for NTSC. There must be two places to change. One for TEXT and one for HIRES. Exactly 2 places need to be changed $1E->$1C and $1A->$18. Here is why (from Dbug's Oric graphics in detail ): 24 or 25 Switch to TEXT mode (60 Hz) 26 or 27 Switch to TEXT mode (50 Hz) 28 or 2...

Re: Need help fixing Oric 1

Does anyone know if it's feasible to remove all 8 dram chips and replace it with one SRam chip like 62256. No it's faster and cheaper. I think we can use Ras to latch address. Speaking technically - yes, it's possible such replacement - you'll need 2x 'LS374, 2x 62256, 1/3 'LS04 and lot of enthusia...

Re: Is BD-DOS lost to time?

About using a PC, the only solution I've seen so far is Greaseweazle . @Chema : Thanks for the link. I didn't know about this nice project - it looks great. I've created something similar based on Arduino but it's in early stage, so Greaseweazle will save my time for something else :). Cumana rebor...

Re: Need help fixing Oric 1

Maybe this is a clue. When the prompt is up (before it goes blank), it says "47870 BYTES FREE". I thought it's supposed to be "37631 BYTES FREE" where's the extra coming from? The number is consistent. 47870 BYTES FREE are absolutely OK - simply you have BASIC ROM ver.: 1.0 3763...

Re: IJK-egoist new joystick interface by [raxiss]

In any case, using a joystick to control a cursor is horrible (keyboard is too, I know). The interesting thing is that using joystick in Blake's-7 is not so bad, actually is very smooth and cursor is very responsible. About the vertical movement: current state is: push - cursor moves down, pull - c...

Re: Need help fixing Oric 1

I need to concatenate the binary to fit the space. Is that true, if so can some one tell me how to concatenate it? in windows that is. Use command prompt and type: copy /b diag.rom + diag.rom diag32k.rom In Oric pin1 is connected to VCC, so A14 will be always HIGH which means only the second half o...

Re: IJK-egoist new joystick interface by [raxiss]

Here are answers to all questions from above : :) I love the design and how it fits on the back of the Oric. What worries me most is the mechanical stress on the connector... something to worry about? I don't think that should be a problem really, I've seen issues with the connections to the flat c...

This is actually very true! In most cases with merge conflicts this the best practice to resolve them quickly. :)

@SteveM : Thanks for all your BD-500 scanned docs.

Re: IJK-egoist new joystick interface by [raxiss]

Games often use only one joysticks, if you add the IJK code for all games, this interface will be a revolution in the Oric world! :shock: 8) Thanks, @ kenneth ! Your words are like nice spoiler for my software surprise: all games adapted by Micropuce for PASE interface (i.e. JOYSTICK ADAPTER I &...

Re: New Spanish text adventure!!!!

Congrats! This is really impressive art work and this is how nowadays all new production for our Oric should look like.
And I already know what ¡Ayuda! means, so it's not too difficult to learn Spanish :lol:

Re: IJK-egoist new joystick interface by [raxiss]

... can anybody test if the IJK detection and joystick managing routines in Blake's 7 work? Definitely, I'll check it asap! But looking in sources there should be no problem, even more - the code for right joystick is commented out - cool! :D About the multiple choices: there will be more... ;) and...
