09:25 PM Feature #13: 32x speed cpu without wait states: Nope, this is not going to be so simple... Massive timing violations. foft

08:27 PM Missing parts: Panos is waiting for the last few remaining parts to arrive. Most notably the FT232 USB chip. We're expecting they wi... foft

10:15 PM Feature #14: Svideo core for first prototype: Debugged in isim to get lots of overflow/underflow/blanking/burst incorrect cases!
Added colour bars and asserts for... foft
06:40 AM Feature #14: Svideo core for first prototype: Scaled luma with 64 space for chroma - when in composite mode only. No point throwing away svideo brightness.
Adde... foft
06:38 AM Sub PCB - now populated!: !sub-board-pop.jpg! foft

09:06 PM Sub-board: Here is the first picture of a sub-board, which also arrived in Greece. None completed yet but all the parts fit - an... foft
09:01 PM Video DAC regulator patch: Here is a picture of the patch Panos has skillfully applied to the boards.
!patch.jpg! foft
08:58 PM Boards received: The boards arrived in Greece. Panos is in the process of adding some final parts and trying them out.
Some good n... foft

08:54 PM Feature #14: Svideo core for first prototype: Setting this up in the simulator so I can understand chroma better.
The problem seems to be that I've used all the... foft
08:51 PM Feature #13: 32x speed cpu without wait states: I have something working on the simulator - alone. Now need to plug it into the core proper to see if it works. Will ... foft

10:14 PM Feature #14: Svideo core for first prototype: Should add that this should not be done for direct chroma output for svideo... Since that is still on a 0-0.7V DAC ou... foft
10:14 PM Feature #14: Svideo core for first prototype: Panos tried out a new core with composite only - on green using the sync pin. Looks brighter but just black and white... foft
07:58 PM Feature #14 (Closed): Svideo core for first prototype: Waiting the Chinese sun to rising, I decide to proceed with the "video mod" of our v 1.0 board. So I desolder the "vs... foft
07:56 PM Pictures!: The PCB company sent us an initial picture!

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... foft

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! foft

09:46 PM Feature #1: Svideo sync line support: admin wrote:

08:35 PM Feature #1 (Resolved): Svideo sync line support: Implemented in test core, probably will need some debugging... foft

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, sinc... foft

09:37 PM Feature #2 (In Progress): PBI support: foft
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...
foft
08:41 PM Feature #12: Set up redmine backups!: Added file backups
Both these are as crons under postgres_backup user foft
08:23 PM Feature #12: Set up redmine backups!: Added postgres backups.
TODO: verify it runs from cron ok foft
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
07:45 PM Feature #10 (Closed): Set up email in redmine: Found password, set up config and tested ok. foft

hi Panos
THE COMPONENTS WILL COME HERE ON MONDAY
THEN START to fabricate
