Well, I never understood why to use CPRs instead of ROMs directly. A CPR file has no advantage (or has it one?), but just fills in some bytes for no gain. What do you think?

Suggesting to move to read ROM content in general! 

Advantage, you can gainz some bytes on a 16 cores / 64Gb RAM machine with 32TB HDD ...

I have now fixed and re-checked all comparator pins, they are all fine now. I have been able to do this without having to remove the capacitors. However, the CPC image was still black after that.

So I soldered each THT hole from above and filled solder into each hole. People in another forum wrote that they had the same problem when the hole wasn't entirely "filled". I don't know what's special about this PCB, because there is definitely a via on each hole.

Anyway, after that there was some progress. At least I am now seeing something: 



The bright green lines are text lines that are not displayed properly (and they are vertically a little off towards the bottom). When I type something, I see a new line appearing.

Any hints what could be missing when the picture looks like this?

And CPR contains information about how the ROMs need to fit into slots, which pure binary ROMs require the user to understand.

And it's much much easier to handle one single CPR instead of dealing with 8, 16, 32 or what ever number of single 16K ROM files.

IMO You are viewing this from a developer's perspective.

From a user's point of view, it makes perfect sense to me to have a dedicated file format for cartridges.

One for tapes, one for discs, one for cartridges, one for ROMs.. all good.

Oh, that looks dodgy. Have you removed all the socketed IC's and cleaned their pins?

Bryce.

I did not try that. However, I did try and press all of them to make sure they were secured in place. My oscilloscope will arrive today or tomorrow so there is much to do next weekend.

Hello,

any news since the November 2024 version ? Once again something I didn't write about it on my web site, I will  correct this tonight.

Does anybody here know how to use 2 disk faces on M4 ? I'm still unable to play it on real hardware.
