09:29 PM Bug #74: Mounted disks don't always load: Implemented using sio clock out as the zpu clock input. Should mean it can listen to whatever speed. Though of course... foft

09:38 PM Bug #74: Mounted disks don't always load: I'd added a 2ms delay temporarily to stop some fast/slow flip flopping. That actually breaks USB keyboard when in tha... foft

09:31 AM Bug #74: Mounted disks don't always load: Ok good. That’s as I hoped. I still need to make switching from slow to fast sio and back more reliable, I just fixed... foft

10:01 PM Bug #74: Mounted disks don't always load: It doesn't seem to be happening as much although I did run into some weirdness a couple of times that might be relate... Farb
09:53 PM Bug #74: Mounted disks don't always load: Farb, are you still running into this with the latest builds? foft
10:00 PM Feature #73: Implement ATX disk image support: Ok, I just checked in a couple more changes. Your patch file should get pretty small now :-D Farb
09:37 PM Feature #73: Implement ATX disk image support: So this is what I ended up with as a patch to atx.c.
I'm updating gTrackInfo on every disk change or access to dif... foft
09:44 PM Core v28: * atx support, thanks to Farb
* fixed disk change sio ack bug (swap file read before ack led to failed reads on disk... foft

04:40 PM Feature #73: Implement ATX disk image support: That's great, thanks. foft
04:09 PM Feature #73: Implement ATX disk image support: Ok, done and checked into v09 branch. Farb
01:44 PM Feature #73: Implement ATX disk image support: Could it be changed somehow like this? i.e. move the avr parts to another file and add byte swapping? foft

11:08 PM Feature #73: Implement ATX disk image support: Oh, and let me know if there are things I can do in the atx.h/c code to make it easier for you to consume :-) Farb
11:07 PM Feature #73: Implement ATX disk image support: I just updated to atxv5 and confirmed that 107 all passes and the few games I tested worked great. Fantastic work!! Farb
09:47 PM Feature #73: Implement ATX disk image support: I put this up as atxv5.
So 107 all passes, but 107 track35 seems to have a lot of NOKs... foft
09:39 PM Feature #73: Implement ATX disk image support: Updated to the v9 code.
I need to split out the eclaireXL changes to make this easier to update. I was going to m... foft

09:45 PM Bug #74: Mounted disks don't always load: Added more structure to the command handling (common ack/nak etc) and looking much better. More to do though... foft
09:57 AM Bug #74: Mounted disks don't always load: I guess a disk revolution at 288rpm is 200ms, so it must be ok timing wise to do the ack first. foft

09:34 PM Bug #74: Mounted disks don't always load: The time spent on iii is in pf_open, the fat file system open. I guess this must do some work.
Perhaps if I ack fi... foft
09:22 PM Bug #74: Mounted disks don't always load: So 3 problems...
i) Sometimes bad checksum, must be a sync issue with pokey clock I guess.
ii) Flip flopping betwee... foft

09:41 PM Bug #74: Mounted disks don't always load: Hmmm, gets a failed checksum on the first sector read and switches to high speed sio. Then takes a while to resync.
... foft
08:45 PM Bug #74: Mounted disks don't always load: Setting up the logic analyser to check the cause of the first few fails on the scanalyzer... foft
08:51 AM Feature #73: Implement ATX disk image support: Thanks. It loaded more on the 400/800 rom (but not that far) and stopped early on the XL/XE. I think I have the patch... foft

06:00 PM Feature #73: Implement ATX disk image support: I just tried it with SDrive Max and Eclaire in XL/XE mode. It loaded and I got to the point that the plane was on the... Farb
05:31 PM Feature #73: Implement ATX disk image support: Hmm, will check the timing some more.
Does flight sim II work on the max? I remember that being time sensitive and... foft
03:58 PM Feature #73: Implement ATX disk image support: I just tested Bandits with SDrive Max and Eclaire XL in 800 mode. It works fine. You need to wait until the full game... Farb
08:41 AM Feature #73: Implement ATX disk image support: Hmm, Bandits just worked with no change. Perhaps related to the other sector error issue. foft
08:31 AM Feature #73: Implement ATX disk image support: I'll put it up as atxv4 shortly.
Tested the few you sent. They all seem to work, except Bandits still does not pla... foft
12:02 AM Feature #73: Implement ATX disk image support: Fantastic! :-D Farb

09:42 PM Feature #73: Implement ATX disk image support: Now M.U.L.E. works:-) + Bruce Lee. foft
09:41 PM Feature #73: Implement ATX disk image support: Ooops, had the subtraction backwards in waitForAngularPosition, doh. foft

08:40 PM Bug #74: Mounted disks don't always load: Probably about time I fix this, might be impacting some atx loading too. foft

12:56 PM Feature #73: Implement ATX disk image support: Here's further info about those two disks:

12:55 PM Feature #73: Implement ATX disk image support: I believe phantom and duplicate sector are synonymous. Yes, multiple sectors with the same number on a track. Both Ag... Farb
12:50 PM Feature #73: Implement ATX disk image support: What is a phantom sector? Same sector number and valid/crc error/weak on same track? Do you have examples for one on ... foft
08:50 AM Feature #73: Implement ATX disk image support: I quickly confirmed that changing $F7 to $EF didn't break any of the images I ran the Scanalyzer test and it returns ... Farb
07:19 AM Feature #73: Implement ATX disk image support: Hmm, good point. The status bits are active low which would make $F7=11110111 and $EF=11101111. Bit 4 represents reco... Farb
07:03 AM Feature #73: Implement ATX disk image support: Why does the code default to 0xf7? It says that means ‘data crc or weak sector’ in the hardware manual. The comment i... foft
06:22 AM Feature #73: Implement ATX disk image support: As you have already surmised, the status byte returned from loadAtxSector contains the FDC status bits. Are you takin... Farb
