I think a good soldering station/hot air is a good investment for these kind of projects .

This morining I did a reflow on the S-RAM ,after that the Ram Issue are now gone ,

I have a TS100 iron that I like very much. I think I even like it better than the new one still, but we’ll see.

Yeah, depending on the result I get with the test firmware I can see some reflowing in my future

MBRTest-2, is it any good? Can’t seem to find a download while googling

Mbr test , will do actually the same as SYStest ,but with SYStest to get out you have to reboot your machine ,in that I like to use MBRtest for workbench.
I received a utility disk when I bought an a1200 expansion from Microbotics a long time a go ,but you can still find it here :

I have good hope you get your TF534 up and running as well, would be real fun to see the TF534 running on an A600

8 Bit Dreams got an adapter from me and has the TF534 running on the A600. A bit unstable, but still

Also, I’m not considering myself to be either stupid or really bad at soldering, so I think it’s a bit unfair how much problems I’ve had with building both the TF530 and the TF534

this will make the fastram low priority and not get code run in there . You should then be able to load systest from a cli.

So... With the test firmware I could boot AmigaTestKit and add the TF534 RAM with low priority.

Running the memory scan gives me errors. Looks like one of the chips isn’t good at all. Bad GND or VCC connection maybe? Or bad chip? IC8, right?

OMG. Seems to work now. I think it was either a bad ground connection or chip select or something. Reflowed the RAM chip and now it seems ok.

To be continued

The IDE might be the next thing giving me problems, but I will try a couple more cards before I start complaining again

Reflowed the RAM CPLD, again, and now I was able to install OS 3.1.4 to a CF card. I will prep a ClassicWB card tomorrow and load it with some games and demos, but it feels like I'm soon ready to build another one. I need to master this
