Re: Hello - I'm a Commodore user in an Atari world here ;-)

:welcomewave: I was an all time Sinclair and Atari user, but I now own Atari and Commodore stuff. That rivalry of which is the best computer is something of the past, now it's childish.... So, being a Commodore user in an Atari world shouldn't be something weird, isn't it? ;)

Re: Redhawk668's TF534 build.

I am getting back in this project, I've put it on hold for a while, but with new PCB's and some new components I will build a new one. I will use the 68030/68882 combo from my TF530. This time it will result in a working TF534.

Re: REV H1 information and interest

I've been following this for some time and I would like to contribute to this project too, so could you put me on the list for one board?

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.

Re: Redhawk668's TF534 build.

I've started the build:

Both CPLD's soldered on + 3.3 volt regulator

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