Re: Oricutron - windows issue?

I tried in Oricutron 1.2 windows version and one dev version I have around (Oricutron_win64-20181004 including sdl and sdl2) and it does not boot.

Re: The BIKE Atmos system.

My point was just: more older sticker means more pain by removing :). I don't actually agree with that, many of the stickers I had on retro computers stuff, either on cardboard boxes, tapes, computers themselves, etc... are generally trivial to remove (undamaged) with a hair drier because the glue ...

Re: Space Cowboy - Demo [raxiss]

Also, I regularly mention it, but in "normal LORES 1" you only have 64 available characters, but the 96 of them are fully available, it's just that this conflicts with the few first lines of the TEXT screen, which can be solved by having the start of the screen in HIRES; which allows you to display...

Re: Space Cowboy - Demo [raxiss]

I still can't imagine a good mix of the two modes lores0 and lores1. I change the charset between lores 0 and lores 1 every other line so that I could have the two charsets available for my tiles. Many graphic element designs have tiles which are exclusively used in odd/even rows. That makes sense ...

Re: Oric V23 Modem

¡¡Please, STOP connecting the interface to RS232 port on your PC. Your PC is sending +12V, -12V pulses to a TTL input (+5V, 0V)!! Maybe the 7404 or the 6551 ACIA are already fried. :-( Quite a sensible advice! That is why I asked some posts ago about the voltages. Checking this is important. Howeve...

Re: Oric V23 Modem

By the way, an oscilloscope or signal analyser would do wonders debugging this... You can check the actual signal values when sending/receiving a byte and see what is going wrong whenever you get receiving errors.

Re: Oric V23 Modem

Should I just get this +5 signal from somewhere to CTS and or DSR as suggested by Chema? I really don't understand this idea ?! If this is to permanently activate (for instance) CTS - you should feed minus 5V relative to GND and disconnect the other side which sends RTS Could be nonsense, really. I...

You should try on Facebook groups or on ebay. The nova is quite rare and should sell easily.

Re: Oric V23 Modem

In null modem you don't need flow control, but I am not sure at all about how the serial interface behaves... What I can tell is that you can wire an cross rts/cts signals in null modem and select rts/acts as flow control and it works if both equipment support that, for instance two PCs. The fact th...

Re: Oricutron HFE

My emulator supports both CPC-style [e]DSK and HFE This is really nice! I think that eDSK is quite similar (albeit more powerful?) to the Oric DSK, so conversion/migration should not be that difficult. I know it could be a nightmare to convert all our games in all the repos, but if the emulator sup...

Re: Cumana Reborn DSK support

With 2A there should be no problem, imho. Dbug, does the Oric which does not like the Cumana work with Cumulus? I still think the bus signal problems (mainly MAP, which is precisely what is usually adjusted with a potentiometer) are to blame. iss wrote he found a solution by pure chance, but I am no...

Re: Oric V23 Modem

Back to the topic and to my post :)

I am sure you tried, but it makes no harm to ask... Did you try to feed +5 or -5 volts (to set mark or space) into CTS (and/or DSR)? It might be just a problem with the Oric side not signaling that the other side can transmit data...
