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... foft

Adding svn backups too while at it.
Need to do these to the raid instead of to another local disk though really...

Added postgres backups.
TODO: verify it runs from cron ok foft

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. foft

FO 07:45 PM Feature #10 (Closed): Set up email in redmine

Found password, set up config and tested ok. foft

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 admin

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 admin

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. admin

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. admin

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... admin
