The last TF534 is here

Looking good TF.

So visually I can see a different cpld on the top and then ic10 is new when compared to the 530.

For those who don't follow YouTube etc, what's the main aim / difference between this and the 530 etc?

1. more RAM
2. put the ram in the Z3 space so other Z2 ram boards dont clash with it.
3. It has a bus buffer for stability.
4. Completely redesigned clock.
5. 44pin IDE.
6. Serial flash ROM onboard (unmapped yet).
7. Its 4 layer so its much more stable.
8. More capacitors for stability.

Once this is out I'm not going to sell the TF530 anymore.

Sounds good. And this is the one you are aiming also at the ST? With your TFBoard right?

Not got my 530 working yet but already interested in the 534.

The TF534 has been a PITA. But hopefully it will be out soon.

The TFBoard is for any 68000 system. Its not really paired to work with the 534 specifically.

Thank you :dualthumbup:

Of course being a dumbass I forgot I didnt have all the parts i needed for this board anymore.. RS order placed.

Excellent, looking forward to ordering two of these boards when they hit EBay. So that's a XC9572XL for bus and XC95144XL for ram? What ram and buffer chips should I be on the tentative look out for or has the BOM already been put up/discussed somewhere?

Cheers for all your hard work!

Also Stephen, if you're doing a video on building one of these latest revision boards or Readme update could you include a minimum component list and build order to get the essential components on the board to just allow programming of the CPLDs?

That would help a lot as I'm somewhat lacking in the diagnostic equipment dept!

Cheers.

The BOM will be published when the board is released.

With all my boards you simply need to put all the CPLDs on and the 3.3v regulator to program the CPLDs. You then need to apply 5V to the 5v rail somehow and program away.
