FO 09:55 PM Bug #74 (Closed): Mounted disks don't always load
Closing as I think this is fixed in v29. Reopen if problems still seen! foft
FO 09:54 PM Core v29
More in-built sdrive improvements...
* Upgrade to latest ATX code
* Fixed SIO high speed selector in menu
* Uses Atari SIO output clock for receiving data
* Replies using same divisor

FO 10:08 PM Bug #74: Mounted disks don't always load
In the end I chose to use the SIO clock for receiving command packets. I also count the rate. Then I reply using the same rate, creating my own clock.
I also fixed the divisor selection, it was not using the valid from the menu!
Wi...

FO 11:48 PM Bug #74: Mounted disks don't always load
Except I need to send start bit from zpu to start that clock. Probably a fairly simple state machine change, but getting too late now! foft
FO 10:53 PM Bug #74: Mounted disks don't always load
On second thoughts, why guess when I know. Pokey is already outputting the serial input anyway (even in input mode, since its oe/in/out which is then connected to the pin). Then I can remove all the divisor guessing logic and code. foft

FO 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 there is still the question of what speed to reply at. Of course I do know what the pokey divisor is but it feels like ... foft

FO 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 that state. Decreased it to 100us for now, though really I need to get to the bottom of what is going on.
I have a cartr...

FO 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 something that made it enter that state too often. foft

FA 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 related so I'll keep an eye on it. Farb

Farb, are you still running into this with the latest builds? foft
FA 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
FO 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 different drive, to save space.
I think I had issues with not being able to change globals if I assigned a value, so I r...

FO 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 swap)

FO 04:40 PM Feature #73: Implement ATX disk image support
That's great, thanks. foft
FA 04:09 PM Feature #73: Implement ATX disk image support
Ok, done and checked into v09 branch. Farb
FO 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

FA 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
FA 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
FO 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...

FO 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 make a diff from v8 and apply with patch, but I don't see v8 any more? Anyway merged and don't think I missed anything si...

FO 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
FO 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
