Ok! I've read somewhere that it is sometimes necessary to daisy-chain autoconfig-out to the autoconfig-in of any following device. Is this only relevant if there are several devices on the bus and you wish to set the order of their configuration?
I've explained this many times.. The Amiga doesnt see the autoconfig requests until the TF card is configured. So nothing like that is needed. possibly You might have an issue with the mem68k board and trapdoor expansions at the same time... but the TF doesnt get involved in that.
Yeah, sorry.. I suspected it would work like that but could not remember reading it anywhere.
Isn't the trapdoor memory kind of "scanned" at boot though? Anything connected to the side connector I can imagine might clash right now, but the trapdoor should be ok?

Thank you for checking this.

Just wanted to share my experience with Mem68k...

It works fine with my A2000 setup - TF534 + Buddha IDE + ZZ9000 + Mem68k
It's a great little inexpensive memory board.

I got my set from eBay, but I can see that he had only 2x2 set available ( 2x ram68k and 2x ide). Still good value for money imho if your can get ram chips : https://rover.ebay.com/rover/0/0/0?mpre ... 3057602622

Unfortunately I can't see "part sets" (ram+ some caps, led etc.)

He had them ready built as well few days ago.

I purchased mine from mkl who sells them on Amibay.
The thread is called 'A500 IDE adapters, PS/2 mouse adapter, A600 CF adapter'

He was also selling them on Ebay up until a few days ago. It's possible that he has no more to sell.

I have noticed that with this setup, I can't overclock 33mhz cpu even to 40mhz. It is not a big deal, as I am not after speed, but it took me whole day to figure this out. I thought that I had connection issues, as tf534 on its own behaved very well, but with memory started crashing.

Yes, because these 8MB are 16Bit wide, and 4MB on TF card are 32Bit wide, so this 8MB (or any additional) card acts like a handbrake for whole system, it runs slow as stock 7Mhz CPU then..
Just be patient and wait till TF536 arrives, im sure this day will come..
