Ok folks here is the TF1260 Rev 1.. Am just working on the silkscreen a bit because ... lets face it. I suck at silkscreens. So i'll put some insulting messages in there for people to find.
Major changes..

1. Dimensions shrunk 5 - 6mm everywhere (hopefully fits in the case this time)
2. The clock multiplier has been decoupled to high hell AND we now use differential clock signals from it to the CPLD.
3. On board data bus is has series termination.
4. TIP + a few more missing signals are now sent to the RAMCPLD.
5. 50% more CPU decoupling caps.
6. Software switchable FAN.
7. Reset lines fixed.
8. Test point on the board for the PLL output channel 1. (we now use channel 2 - differential).

-- and things i forgot..

9. Therm header.

Do not underestimate the work for #1 here. it took longer to do that than the original routing.

Awesome stuff, and great that you put a THERM header on it <3

Those caps will be the death of me. But it's a small price to pay to make this card available. I wonder what are the chances we could get caps preassembled by the board house?

Very probably... I'd be happy to ask them to do all the low cost items.

Free SMT assembly with PCB orders at JLCPCB until 12th Jan. Only pay for the components used - caps count as standard items. Restricted to one side only.

Bit more work for you to create the appropriate pick and place file.

That is rather odd.

They claim to do both 2 and 4 layer now in their "Assembly Capabilities" section.

If they dont... I have a contact that can do the assembly in Scotland.. Probably not as cheap as JLCPCB.. but since he was my Best Man maybe i'll get a good rate (probably have to do the setup myself).
