OK, have to call it a day for today. I'll put up v3 with the latest anyway, though I suspect not much really helped y... foft

09:15 PM EclaireXL Feature #73: Implement ATX disk image support

OK, can reproduce the same results in the linux sim... Which is good. So its not a missed byte swap (there is no byte... foft

09:05 PM EclaireXL Feature #73: Implement ATX disk image support

Yeah I wired status up right after building atxv2. I am getting back 0xf7 though. Its not finding the sector in the l... foft

08:33 PM EclaireXL Feature #73: Implement ATX disk image support

OK, little better. Now getting 247 on 19,20,... and 28,32. Investigating why the status is not 239 now. foft

08:26 PM EclaireXL Feature #73: Implement ATX disk image support

I think the first few errors may be related to the bug 74 you raised.
I do see failure on those sectors though I w... foft

If it’s that broken I wonder why air strike, Bruce Lee and lode runner work.
I’ll try that tool... foft

An aside, but noticed I seem to have a bunch of hexdumps still in this code. Better remove them since I'm sure they t... foft

09:51 PM EclaireXL Feature #73: Implement ATX disk image support

Nope, still seems to hang on most things. Hmmm. foft

09:50 PM EclaireXL Feature #73: Implement ATX disk image support

Trying to hook up sector status to 0x53 to see if that helps foft

09:34 PM EclaireXL Feature #73: Implement ATX disk image support

Fixed that and put it up as atxv2.
Load a bit quicker, but still only a few things seems to work (baker street and... foft

09:09 PM EclaireXL Feature #73: Implement ATX disk image support

Seems that it was just a + vs - issue when calculating the wait on rotation. Doh. foft

06:31 PM EclaireXL Feature #73: Implement ATX disk image support

I think something might be wrong with track step or something. Since its loads slow, slow slow, then occasional fast.... foft

06:30 PM EclaireXL Feature #73: Implement ATX disk image support

I've put the rpd there now. foft

Oh, forgot to copy that! Will do that this evening.
I was thinking a test suite would be great. On an atx that boo... foft

Farb, I've put the latest test version here. Can you give it a try please since you are more familiar with how the be... foft

08:44 PM EclaireXL Feature #73: Implement ATX disk image support

Added byte swapping and changed the wait_us delays to be in us. For some reason wait_us(3.22*1000) was hanging rather... foft

09:33 PM EclaireXL Feature #73: Implement ATX disk image support

If I comment loadAtxSector it does not hang, so must be something stuck in a loop in there. Will instrument and print... foft

09:27 PM EclaireXL Feature #73: Implement ATX disk image support

Now the core is working again in general: USB, atr, xex. I can insert atx disks, but they fail to load - firmware han... foft

I got the core building but I've broken it enough that usb no longer works... ooops, will have to debug another day. foft

10:02 PM EclaireXL Feature #73: Implement ATX disk image support

There are the default (original) sdrive delays in us iirc. If an ack is sent too soon it can arrive before the sio co... foft

Closed. Working fine with my Veronica clone and no feedback received from tester. foft

10:01 PM EclaireXL Bug #64 (Closed): Pokey pdm timing incorrect

Found the issue when doing the pokeymax work - I'd lost some changes by accident. foft

OK, so for all intents and purposes I think its the same. At least until we add the split bus for the 800... I added ... foft

Great! Going to close this until I decide to add 2 bus support or you find a bug in it:-)

Did you load the original OS B or use the one off the jic? I think the one I included on the jic is patched. I should... foft

07:46 AM EclaireXL Feature #68: Implement stock Atari 800 mode

I’d better wire up the atx code so I can try it myself:) foft

Fixed the beep on reset. Will build as v26. Not sure whether floating data bus if worth it. Looks like it wasn't even... foft

09:23 PM EclaireXL Feature #68: Implement stock Atari 800 mode

That worked... Now for that horrible beep on reset. foft

09:17 PM EclaireXL Feature #68: Implement stock Atari 800 mode

This is due to a brk being hit when it jumps to the cart to initialize it. Making the bus 0xff when no ram present wh... foft

Built as v25 anyway in case anyone wants to play, but definitely more to do on this... foft

09:48 PM EclaireXL Feature #68: Implement stock Atari 800 mode

Squashed several bugs, but struggling with 16k and 32k mode for some reason, not booting. foft
