Tape / WAV testers please
Hi all, I need your help for a few quick tests! :D If your Atmos is out and ready to load (through the tape port) WAV files played by your computer! Warning: ROM 1.1 required . The goal is to have statistics on how Orics precisely read some tape signals, to try and make a fast load routine as reliab...

Re: New tape loading speed - testers needed!
I've updated the tool, changing the waveform so the signal is smoother for the 6522 (I think the previous version was not that good).
If you ever failed to load, you can download and try again!

Re: Experimental very fast tape loading
I would be curious to see side by side with the "normal" way of working. Routines loading excluded : Very fast : 3.2 seconds Tap2CD : 6 seconds Standard : 57 seconds :lol: (ok, with synchro) For the network part I think that using the audio card is not a good idea, it would be better and ...

Re: Experimental very fast tape loading
Congrats! The speed is really impressive. I think you can extend the idea and create kind of networking trough the tape port ;). Thanks ! Networking PC and Oric through the tape port is an idea I've explored for yeaaars, but needed to improve skills on various sides: - how to allow the Oric to be i...

Experimental very fast tape loading
It's all there !

Sadly can't seem to be that fast and work on any machine. As soon as I change, I have to (very painfully) set up again several parameters.

Re: Invert Carry
Indeed! Thanks for your help guys, sorry I didn't come back on this in detail but it certainly helped me carrying on the project I'm focued on. Significant progress but the hardest part is there: - complicated code and (very) complicated testing to finish - back to work soon so no more spare time ag...

You're right!Dbug wrote:You really need to use a standard notation for the values
My problem is that I use Assembler so sparsely, that each time I go back to it, I forgot and mix with the Basic standard of # for hexadecmial notation

Re: Invert Carry
Okay, another option...
Am I wrong saying that I also can ROR in 2F the C values as they are, and once done do this:
LDA 2F
EOR FF
?
This is not exactly the topic questions but I just realise this is much more efficient...

Re: Invert Carry
Still trying to find if the double SBC is OK - seems to be the shortest way (in time) to do it. It seems that when the result of the 1st SBC is done (replacing the CMP), the 2nd SBC inverts C correctly - but this is strictly theoretical. Edit : too bad, actually I'm not sure C is always =1 before th...

Re: Invert Carry
Thanks for the replies - amazing to see so may ways to achive something ;) Here's another try, which I'm not sure yet if it works anytime: Hint: I know for sure C=1 when I begin this code (that helps, I should have told you but I only noticed it because I needed it for this attempt...) SBC#$A4 2 cyl...

Re: Invert Carry
Because yes, CMP update the C flag, you want to ROR your data and put the reverse of the current C value that's right? Yes that's it, I'm RORing a byte in memory (not the accumulator). Here's exactly what I'm doing right now: ADR Cycl Hex Code Comment 04B7 2 C9 A4 CMP #A4 Sets C 04B9 2/3 B0 04 BCS ...

Invert Carry
Hi, I need help ! Is there a fast trick to invert the value of C (carry) without having to test it and use CLC/SEC ? What I'm trying to do: I'm doing a CMP XX which sets: - C to 1 if the accumulator is superior to XX - C to 0 if the accumulatore is inferior to XX But then I would like to ROR in memo...
