Re: Cumulus Issues

Thats correct, but with one caveat, high rated power supplies can have problems maintaining the advertised voltage if they are under-loaded, but I don't think it really applies here :-)

Re: Stuttering Atmos

Clearly the 6502 is executing the ROM correctly (and also must be reading/writing RAM correctly), and the ULA is reading the char ram correctly, but is reading the screen ram with bit 0 stuck at 0.

So it looks very much like a busted ULA.

Re: Stuttering Atmos

Never saw that :) Interestingly, the characters are duplicated but not the pixels inside the characters, so that's probably not a bus access issue. It is reading all the even RAM addresses, so it does appear to be an address bit 0 issue. It could be between the ULA and RAM, but not between ULA and ...

Re: Stuttering Atmos

I think you mean ULA :) To change the ALU he'd have to cut open the 6502 and remove and replace a section of the die! It looks like the bit 0 address line to the ULA is stuck. Edit: Which means the problem could be on the PCB trace to the ULA, or inside the ULA. An oscilloscope on that pin of the UL...

Re: Oric ROMs

I still think a good idea for a future revision of the cumulus would be to map in a rom image from SD when software de-asserts romdis.

Re: How Opening SNA files made with Oricutron ?

Open the menu, select "Load snapshot", select the snapshot file... and thats it.

Note that oricutron snapshots are not compatible with euphoric snapshots.

Re: Oricutron patches for Mac OS X

as I recall, its not as simple as enabling sdl keyboard translation, otherwise I would have done it. the problem is modifier keys like shift or ctrl. If you let sdl map keys for you, you won't know what keys were pressed to give you the ascii code. What if the user is playing a game where shift and ...
