Blindguy - got latest firmware in the CPLD?

I think so. tf536_2020_08_02_RC2.zip

I'm using a Megachip clone, some home made thing I bought from a guy on Amibay. It's using a 2MB Agnus from an A600. It's working fine with the TF536.

Mine is working with a Megachip Clone also, using latest software.

Same here, did a quick test, with a PLCC plug-in type Megachip clone (Agnus 2MB 8375 318069-10)
Amiga 2000 Rev 6.2 MB
TF536 in co-processor slot using Matze's A2000 CPU adapter board.
August 2020 firmware on 536.
Works well for myself.

Thanks for the notes guy, I'm going to work on getting a CPU adapter board and retry with that.

Good Afternoon everyone, hope all is well.

So i have tested the TF on a PAL A500 and it works fine so I know the card is good.

I got a riser board for the A2000 and I pulled out the MB cpu and when it boots I can see the rainbow splash screen and I can hear the floppy click once and the screen then goes grey and that is it.
i pulled ALL cards out of the A2000 except for the 2meg agnus mod, I dont have another agnus to swap it out to test.
any assistance is appreciated.

running 3.1.4 roms. ver 4.4 MB NTSC

maybe when I ran it on the A500 it remember some stuff?
Anyway to reset everything or jumpers, caches i need to flip?

There is no nonvolatile settings on the card. There are known issues on rev 4 MB that need patched for cards to work. I only ever tested on a rev 6 motherboard with 3.1 OS.

Success of a bit!!

I switched to digirom and I was able to get it to boot and i can see the cpu and ram in digirom but I still can't get her to boot with the 3.1.4 roms.

I'm going to see if I can try and test other stuff.
I have a 2meg chip ram card thing so its very tight putting the card direct on the MB so I using the riser but as I said, DIGIrom sees the card fine so I dont think it is the slot card or the card it self.

Thanks for all the thougths and I'll let everyone know if I ever figure it out.

I'l also do a bit more reading and see if I cant these patches in place.

Love the work, have a great day.

I have sold to a couple of A2000 owners with no reported problems.
Both required the IDE buffers, although I cant see not having them being an issue.

@alenppc

I've since sold at least another 3
