PLCC to DIP adaptor - TF536 on A600

[Lemaru]

Yes, the internal floppy works as soon as you plug in a 68000 cpu but stops working with the 536. Oddly enough the external floppy always works.

I had a little time to test this today. And with my TF536 fitted in my A600 with KS3.1, I have no issues with my internal floppy. I can read disks in Workbench, and can boot off them fine.

Only one disk didn't boot and that was my backup Workbench disk that I used to use and has been heavily abused. Doesn't boot but can be read in Workbench fine when booted from another disk or HDD. Original workbench 2.05 disks, AMOS, DPaint, Octamed and various magazine disks all boot as expected from DF0

Huh, that's peculiar. I even tried replacing the floppy drive with a different one but same behaviour. As soon as I remove the 536, they both go back to working.

What firmware were you both using?

What firmware were you both using?

The one you can find in the Firmware thread.

[Lemaru]

Very strange. I'm using the firmware @alenppc emailed me a while ago. If I open it in a text editor, the date of it is "Mon Jul 20 20:45:09 2020"

Rev 1.5 A600, with a 1MB ChipRAM expansion, kickstart 3.1. So nothing special about my setup

[bprepared]

I note that Lemaru is using KS3.1, not 3.1.4 so which I think ties up with what you were saying Alen about it only being a 3.1.4 issue?

[alenppc]

The board won't boot at all with 3.1.4. If the kickstart 3.1.4 chip is used, you'll get a black screen after the flashing colour bars. If you load it with a Kick 3.1 chip, it loads until the LOADMODULE ROMUPDATE after which it turns into a black screen.

For the floppy, I may eventually try it on a different A600 (this one is also a rev 1.5). But I am a bit sick of the A600 right now so I won't do it right away.

It may be detecting ram at C00000.. do you have a slow ram card you can add?

I will try and find time to sort the files out a little better once I'm on my next off shift from work and get them up online. I'll stick the link up here when done.

Any progress, or have you put the project to bed?

I haven't had much time recently to be honest. I still have to tweak the design a little, then I'll probably get some more boards made.

I would of stuck the files up already, but have had people requesting the Gerbers, which implies they just want to sell them (probably at a stupid markup). So as this first version was just a test to see how it works and fits, I would rather release it in a more finalised state.

I may have a spare board of the test batch if you wanted to test one.
