Re: Redhawk668's TF534 build.

So, removed most of the parts of my failed TF534 board and soldered them on a new board. Went allright, only the large CPLD did not come off properly :(, had to order a new one + passives, resistors, etc.

Re: Redhawk668's TF534 build.

It seems that I f*cked up my TF534 build. After finishing it and testing it, it did boot into DiagROM but not in Kickstart 3.1 so went back to the workbench to reflow the CPLD's. That didn't went as planned, two pads lifted while reflowing :( the 144 pin RAM CPLD... Luckily, I have a hot air station...

Made some more progress:

Missing one 1206 0.1uF capacitor on the underside and I have to wait for the PGA128 socket.

Re: Redhawk668's TF534 build.

Done some more soldering, memory, transceiver chip and schmitt-trigger buffers soldered on. I've also soldered the SPI flash chip on the board, I know it isn't used by now, but it's nice to have it already on the board.

I've started the build:

Both CPLD's soldered on + 3.3 volt regulator

First signs of life, both CPLD's are found:

Redhawk668's TF534 build.

As I've received my TF534 PCB's and already ordered all of the needed components in one go, I think it's a nice idea to put my progress here too. Little picture of the PCB: https://i.imgur.com/fgpXHER.jpg Now waiting for all the stuff to arrive. I've ordered most stuff from Digikey, so that will arr...

Re: kludge’s TF530 build

I had the same problem with my TF530, it wouldn’t boot. No clock signal. Turned out to be a short on the BUS CPLD. I reflowed it and my Amiga booted with the TF530 at 50 mhz.
