Re: Next Cumulus batch

Hehe thanks, I'm working on the CPLD for the Cumulus 2, and will probably do a run of prototype in January :) It going to take about 2 weeks for making the PCB so even if I order now, I will not be able to work do anything with it before next year.. So I take my time to be sure that I'm going to mak...

Re: Yet Another

Interesting :) Regarding timers, I wrote some benchmarking code few years ago which allowed us to notice discrepancies between real Orics, Oricutron and Euphoric, so when you have something that can run code, we should be able to help with your timings. Where can we find that code? I would be inter...

Re: Announcing... the AtmoStrat !

Two video pages? And since it's reading the video memory that refresh the DRAM how this is handled? Because I'm sure that if we switch the pages, the ULA will no longer be able to access the main ram, so.. ?

No worries, it will be on eBay sonner than later, it's not collection, but speculation here, especially when it goes that high.

Re: Oric's 8912 volume scale

On the topic, there's some interesting details about sound on Gunstick's presentation: https://www.youtube.com/watch?v=yLDtiTS4JLg Around the 34th minute there are some Audacity sample output of the three channels, and discussion of the shape on emulators vs real machine.

Re: Experimental very fast tape loading

I would be curious to see side by side with the "normal" way of working.

For the network part I think that using the audio card is not a good idea, it would be better and more reliable to use a small microcontroller, probably connected to the PC via USB

Re: Invert Carry

EDIT : sorry I'm not very familiar with ASM syntax (I code in machine code directly !), and I notice I have probably confused some of you with #A4 , which is actually the VALUE #A4, not the content of the memory in #A4. So I should probably have writtent somthing like #$A4 ? Sorry it's me, reading ...

Re: Invert Carry

I'm not sure about DBug solution (It's a bit early.. ;)) But before I see his answer I came to that: CMP $A4 ; Compare value from A4 | 3 cycles (zeropage) ROR $2F ; Do the ROR into 2F | 5 cycles (zeropage) PHA ; Save A (if needed) | 3 cycles LDA #$80 ; Going to reverse bit 7 | 2 cycles (direct mode)...

Re: 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 mem...

Re: Dungeon Demo source code

For the tools, DigitalMars C++ can do a really good job at compiling that, and of course if you are using a 64bit Windows, DOSBox would be perfect! :)

Thanks for sharing that!
