- 09:10 PM Feature #84: Add SID
- Attaching some of the octave files from investigating this for reference + the wave files + other useful bits I found...
- 09:07 PM Feature #84: Add SID
- Did some research over the weekend. Generating these isn't a terribly trivial problem!
I tried for some time to ge...

- 10:19 PM Feature #84: Add SID
- It sounds good to me, but not sure what it is meant to sound like!!
- 10:19 PM Feature #84: Add SID
- Also wondering if the clk frequency is important (not enable), I see some state table increment on every clock, which...
- 10:18 PM Feature #84: Add SID
- Wondering about some kind of bit map of unpopulated locations (reducing locations) or a 2nd lookup layer (reducing bi...
- 10:04 PM Feature #84: Add SID
- I loaded the tables in to octave to take a look.
Observations...
* Not a simple curve
* Lots of zeros, >80% in ... - 10:02 PM Feature #84: Add SID
- Actually the issue with fitting in v2 is block ram, not ALMs. Though its always good to save ALMs!
The sid tables ... - 09:05 AM Core v37 released again!
- EclaireXL/A4: SID frequency was too fast, made it closer to 1MHz (still approx, but better than 1.77MHz).
xxl kind...

- 04:59 PM Revision 959 (repo2): Fix nmi when freezer debug disabled
- 10:05 AM Feature #84: Add SID
- Also got this potential USB sharing, that'd save 750 ALMS. Each request/reply is host initiated, so no reason can't s...
- 10:03 AM Feature #84: Add SID
- 600 alms each, will use mono sid I guess. Or make it a generic and enable on the larger boards?
- 10:00 AM Feature #84: Add SID
- Logic utilization (in ALMs) 9,808 / 9,430 ( 104 % )
- 09:56 AM Feature #84: Add SID
- Have a dual 8250 working, though it doesn't fit in the smaller boards. Investigating why, memory or logic...
- 09:56 AM Feature #84 (New): Add SID
- Agreed to try adding a SID to the pokeymax.
Eclaire is a good test bed for this, so starting out with that - 10:00 AM Bug #69: Some TVs confused by hdmi audio
- Hias had some clever approaches, capturing the digital audio out from the tv etc
- 09:59 AM Bug #69: Some TVs confused by hdmi audio
- I dug into this a bit with Hias. It turned out the issue for him was noise from the dac, so distinct issue. Though I ...
- 09:58 AM Feature #32: option to connect the original ATARI XL keyboard to ExclairXL
- Panos kindly sent me the boards he designed. I put together the bom on mouser and digikey. will order some parts and ...
- 09:55 AM Feature #51: Debug port
- Now I have the saleae I figure I can stream this more reliably to the PC. Will have a go at this soon... Perhaps I wr...
- 09:54 AM Feature #82: Setting for mono pokey
- With adding sid should probably allow that to be on/off too.
pokey 1/2
sid 0/1
2 bits? - 09:44 AM Bug #83: Many USB hubs do not work
- Just did a bit more testing. Two hubs, two keyboards and a joystick. Fiddled with unplugging/re-plugging etc and all ...

- 10:58 PM Bug #83 (Closed): Many USB hubs do not work
- 10:57 PM Bug #83 (Resolved): Many USB hubs do not work
- 10:54 PM Bug #83: Many USB hubs do not work
- Got it, I needed to set the line control earlier on. It was set to 'NORMAL' after the reset and this leads to the SET...
- 10:53 PM Revision 958 (repo2): Set line control earlier on. Otherwise hubs reject the set_address, since it comes too soon.
- 07:39 PM Revision 957 (repo2): Removed non-trunk!

- 10:53 PM Bug #83: Many USB hubs do not work
- This setup is so much better for debugging than on the Eclaire. I have gdb on linux to debug the binary, I can printf...
- 10:49 PM Bug #83: Many USB hubs do not work
- The hub is detected as connected, then it tries to set the address and fails.
So, the keyboards I'm using are low ... - 10:07 PM Bug #83: Many USB hubs do not work
- OK, circuit build and wired up. I can type on the sockit.
Now to get some debugging in place and try the hub.
