- FO 10:19 PM Delays
- We received an update from the PCB company. Unfortunately it wasn't to say 'shipping' as we'd hoped.
Instead they requested some more information for their machine setup, so apparently they have not started assembly yet as promised!

- FO 10:07 PM Feature #13 (In Progress): 32x speed cpu without wait states
- Trying simply feeding in the clock at twice the speed to see if it passes timing!

In all the cases we need to connect the sync pin of dac on a I/O of fpga?

- FO 08:08 PM Feature #13 (New): 32x speed cpu without wait states
- The whole system is clocked at 32*original clock. However the 6502 turbo is limited to 16x due to the ram speed, since a block ram access cycle takes 2 cycles. Try to clock the block ram at 64* original clock as a quick win to get 32x tu...

- FO 09:37 PM Feature #2 (In Progress): PBI support
- FO 08:57 PM Feature #12 (In Progress): Set up redmine backups!
- Adding svn backups too while at it.
Need to do these to the raid instead of to another local disk though really...
- FO 08:41 PM Feature #12: Set up redmine backups!
- Added file backups
Both these are as crons under postgres_backup user - FO 08:23 PM Feature #12: Set up redmine backups!
- Added postgres backups.
TODO: verify it runs from cron ok - FO 07:53 PM Bug #9 (Rejected): Fix svn repository
- Decided to just disable this - its complicated enough anyway an the svn can already be checked out or browsed.
- FO 07:45 PM Feature #10 (Closed): Set up email in redmine
- Found password, set up config and tested ok.
- FO 06:59 PM Parts arriving monday
- Sent on:9:04 amFrom:Eric Wu
hi Panos
THE COMPONENTS WILL COME HERE ON MONDAY
THEN START to fabricate
about 3-4days to ship out

- FO 09:11 PM Bug #9 (Rejected): Fix svn repository
- Repository is not working
- AD 09:08 PM Feature #8 (Closed): Implement 4 channel ADC
- The one channel ADC on the v1 board is replaced by a four channel one on the v2 board.
Modify the implementation to support this - AD 09:07 PM Feature #7 (New): Implement I2C vga/hdmi support
- Try the I2C support on the new board.
Initially for presence detection
Latest for checking modes
Its via a mux chip so we can independently address both ports - AD 09:06 PM Bug #6 (Closed): HDMI audio poor quality
- I removed a low division in the audio output to meet timing. I suspect this should be replaced with a proper low pass filter.
- AD 09:05 PM Bug #5 (Closed): SIDE2 does not work
- SIDE1 works fine, but SIDE2 does not work. I contacted Sebastian and he kindly send me some details. Need to look into this. Suspect its down to dynamic RD4/RD5.
- FO 08:51 PM Bug #4 (Closed): Galaxian flickers on scrolling - when using real cartridge
- Galaxian flickers on scrolling when using a real cartridge. This does not happen when using the virtual cartridge.

- DMACTL bit 5 is normally playfield dma on.
In the core bit 6 is also supported to allow
10 - 2x colour clock - allowing 640x240 - or gtia 160x240
11 - 4x colour clock - allowing 1280x240 - or gtia 320x240

- Implement PBI support:
Done:
PBI_A
PBI_D
PBI_CLK
PBI_RW_N
PBI_IRQ_N
PBI_RST_N
High priority:
PBI_EXTSEL_N
PBI_MPD_N
PBI_REF_N (including turbo freezer hack)
These are tricky because they are sampled at different ... - FO 08:30 PM Feature #1: Svideo sync line support
- A comment
- AD 08:20 PM Feature #1 (Closed): Svideo sync line support
- Doesn't look too hard to change. In the svideo component they do this for luma:
luma = (84*R+164*G+32*B + 58880)/512 (i.e. 115-255 on dac)
luma (sync) = 0 (i.e. 0 on dac during sync peri... - AD 08:24 PM Board ordered
- We've ordered the boards from the PCB manufacturer!
