Last post by Rabs - Yesterday at 21:39Quote from: hatman72 on Yesterday at 20:53That does look very similar, and I have seen mine produce the pattern in different colours occasionally, especially if the cassette deck is plugged in. It does look like a sensible thing to check.Either way I would follow the advice by @Bryce.

Quote from: GUNHED on 11:46, 10 July 25But the M4 is a "black box" for us programmers.Seems, that it should still stay a blackbox when reading this answer.
Quote from: GUNHED on Yesterday at 18:43The problem is more complex and shows only up when reading a DIR entry name. It's solved, so everything is fine.The
C_READDIR
command has to have the ROM visible as well. What is "complex" about this?
I am not using the highlevel features, where the Z80 is not used for filesystem handling at all, but everything is handled by the external ARM M4Board CPU, moving all the intelligence from the CPC to the M4Board. But...
It would be still interesting, what bug you mentioned here, as you are talking about reading, not writing:
Quote from: GUNHED on 11:46, 10 July 25The M4 has a bug: You can't switch ROMs during data transferDid you inform Duke about the bug (whatever it should be?) and will he update the m4info.txt?

to me..this is just silly...
slapping the commodore name on a system doesnt make it a commodore... even if ya have all the licencing...
...and the price is absolutely outrageous

In this video there is a similar screen pattern, sometimes, but also the usual grey screen black border RAM problem display.
You cannot view this attachment.
In this GadgetUK finds that IC112 74LS32 Quad OR is faulty. Not quite sure how the floating output he finds relates to the issue as pin 11 selects the printer latch but pin 8 does select the data latch (by the way I made pin 8 float on my test board and I get the usual grey screen RAM problem symptoms).
No idea if this is the same as your problem but saw it and thought I would share.

I first heard about this a few weeks ago (7.6.) when Christian (Perifractic) posted his idea of buying Commodore on his channel. At first, I thought it was a silly joke, but then it happened very quickly, so it was probably planned for a while.
Christian 'Peri Fractic' Simpson is a nice guy; I wrote with him a few years ago when he did an episode about SymbOS for the Amstrad PCW.
I have no idea how this will end, but for a start, it sounds very nice that an enthusiastic person like him is now a leading part of the new "Commodore Company" team
I wish we could have the same for Amstrad, but I'm not sure how enthusiastic Lord A.M.S. is about the CPC spirit. At least it's very cool and an honor to have the CPC as the title screen of his new website.

If it is the real Ultimate64 (from Gideon) under that case (maybe an older batch, not the Elite I/II), then the price is pretty nice.

What's new?
- File names are now only displayed up to 27 characters long; the remaining characters are hidden because otherwise they would overflow (see Dodogildos post before). I wasn't expecting such long (DSK) names at first.
- Hotkeys are implemented in all three windows. They are the same as in the OS, except for I and O. They are displayed at the bottom of the screen. There are also U for Untag, which untags all file names, and A for retagging ALL previously used files. See: https://www.cpcwiki.eu/forum/programming/futureos-corner/msg250713/#msg250713
- Information help-text at the lower part of the screen.
PDT: The problem is more complex and shows only up when reading a DIR entry name. It's solved, so everything is fine. But thanks for caring.

Quote from: Dmanu78 on 16:47, 06 July 25@andycadley : I'm very curious about your test code. Don't hesitate to let me know if you notice any differences. This will help me improve the emulation.It doesn't seem to like my scan line doubling code:
GX4000 scan line doubling
Haven't really dug into why though. My poor old laptop struggles running the emulation, so it might be time to think about getting a new one.
